PURPOSE OF THE STUDY: The authors present the outcomes of more than ten-year clinical follow-up of patients who underwent surgical treatment of deep chondral defect of the knee (medial or lateral condyle). The method of treatment was the implantation of autologous cultured chondrocytes in the form of a solid chondral graft. The aim was also to compare the mid-term and long-term outcomes and to evaluate how the knee condition affects the everyday life and sports activities more than 10 years after surgery. MATERIAL AND METHODS Thirty patients of the total of 56 patients (26 patients dropped out of the long-term follow-up) operated in the period between 2001 and 2012 were available for retrospective evaluation of the clinical condition before surgery, at 1, 2, 5 years after surgery and at 10+ years after surgery. The mean follow-up period of patients was 14.5 years (10 - 20.5 years) after surgery. The clinical evaluation was performed using the Lysholm Knee Scoring Scale and the Tegner Activity Scale. RESULTS The mean preoperative Lysholm score of the followed-up study population was 37.5. During the fi rst two years, improvement was achieved to the maximum value of 83.1. At 5 years and subsequently also at more than 10 years after surgery, a slight decline was reported to the mean value of 78.6. When comparing the outcomes at 5 years and at more than 10 years after surgery, the decline in the value was statistically non-signifi cant. The mean value of the Tegner Activity Scale at more than 10 years after surgery was 4.5 points out of 10 points. DISCUSSION Management of a chondral defect especially in younger patients constitutes a common challenge in everyday orthopaedic practice. There are multiple methods at hand, all of which have their pros and cons. The size of the chondral lesion appears to be the limiting and decisive factor. The greatest pitfall are large chondral lesions (>4cm2 ), where many methods fail to yield satisfactory outcomes. One of the suitable options is the autologous chondrocyte implantation method. CONCLUSIONS The clinical outcomes of patients followed-up for more than 10 years after surgery do not show a statistically signifi cant decline compared to the mid-term outcomes. Based on the data obtained, we continue to consider the autologous chondrocyte implantation as an effective method to manage deep chondral defects in the knee. The patients were mostly able to get back to normal life, including their sports activities, with a signifi cant improvement of its quality compared to that before surgery. KEY WORDS: knee joint, chondrocytes, autologous cartilage implantation, long-term.

The authors present the cases of monozygotic male twins with right-sided Legg-Calvé-Perthes disease (LCPD) with different formation of the lumbosacral junction. This is likely the fi rst description of a lumbosacral junction formation disorder associated with identical twins who were both treated for LCPD as children. The disease began at 6 and 9 years of age and during treatment as well as in adulthood signifi cantly different bone formation of the lumbosacral transitional vertebra, was observed in both brothers. Twin A has a unilateral right-sided fusion of the enlarged L5 transverse process with the ipsilateral sacral ala, twin B has a complete sacralization of the fi fth lumbar vertebra. The LCPD treatment outcomes in the twins were consistent with the results from large studies, i.e., age at the time of LCPD onset is the main factor infl uencing the prognosis, however the morphological difference in the transitional vertebrae in these monozygotic twins was signifi cantly. Key words: lumbosacral transitional vertebra, lumbosacral junction formation, sacralization of lumbar vertebra, megatransverse of vertebra L5.

PURPOSE OF THE STUDY The competence of the anterior translation of tibia (ATT), posterior cruciate ligament angle (PCLA), and femorotibial rotation angle (FTRA) measured on MR images in predicting anterior cruciate ligament (ACL) injury was evaluated in this study. MATERIAL AND METHODS 266 patients who underwent diagnostic arthroscopy between 2015-2020 were included in this study. Age, gender, radiological fi ndings included ATT, PCLA, and FTRA were measured on preoperative MR images of all patients. RESULTS ACL tear was detected in 143 of patients and most of them were younger males. In ACL-R group, the ATT was 7 mm (-4-17 mm), PCLA value was 110º (52º-157º), and FTRA value was 5.8º (-5º-18º), while in ACL-I group, the ATT was approximately 5 mm (-4-12 mm), PCLA value was 122º (82º-162º) and FTRA value was 1.6º (-10.9º-10º) (p<0.001). ROCCurve test results showed that if ATT value was >6.05 mm (63% sensitivity, 65% specifi city) if PCLA value was <116.5º (65% sensitivity, 70% specifi city) and if FTRA value was >3.45º (73% sensitivity, 72% specifi city), these parameters could predict the probability of ACL tear, preoperatively. The Logistic Regression test results revealed that the PCLA and FTRA values could be the best markers to predict the probability of ACL tear, preoperatively. CONCLUSIONS This study results showed that the ATT, PCLA, and FTRA values could be used as predictive markers in diagnosis of ACL tear, preoperatively. Among these three values, it was concluded that the FTRA could have the highest sensitivity and specifi city ratios and the best predictive value. Key words: anterior cruciate ligament tear, magnetic resonance imaging, arthroscopy, rotational instability, femorotibial rotation angle, anterior translation of the tibia, posterior cruciate ligament angle.

PURPOSE OF THE STUDY Femoroacetabular impingement syndrome is a complex, often post-traumatically developing impairment of the hip joint, characterized by ambiguous symptomatology, which makes early diagnosis diffi cult, especially in the early stages. Experimental retrospective study was carried out to evaluate the usability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. MATERIAL AND METHODS 92 patients were included in the retrospective study, and 62 completed the investigation. All patients signed informed consent. A gyroscopic sensor was placed on the right side of the pelvis above the hip joint, and the patients walked approximately 15 steps. Furthermore, an evaluation of the data during stair climbing and a complete clinical examination of the dynamics and physiological movements in the joint was carried out. Data measured with a gyroscopic sensor were processed using differential geometry methods and then evaluated using spectral analysis and neural networks. The proposed technique of diagnosing FAI using gyroscope measurement is a fast, easy-to-perform method. RESULTS Our approach in processing gyroscopic signals used to detect the stage of arthrosis and post-traumatically developing FAI could lead to more accurate early detection and capture in the early stages. CONCLUSIONS The obtained data are easily evaluated, interpretable and benefi cial in diagnosing the early stages of FAI. The results of the conducted research showed this approach to more accurate early detection of arthrosis and post-traumatically developing FAI.

PURPOSE OF THE STUDY The study aimed to propose an optimal based fl ap creation with the view to ensure long-term survival of the interposition arthroplasty. MATERIAL AND METHODS A total of 28 dorsal wrist capsules were collected from 16 cadavers (with age range at death 18 to 80 years, with no visible wrist pathology). Altogether 112 histological specimens were obtained from these 28 samples. Post-hoc Dunn's tests were used to analyse the percentage of vascularisation of individual sides of the dorsal capsule (circumference and area) at the 0.05 level of signifi cance. Spearmann's correlation analysis was used to assess the effect of age on vascularization of the dorsal wrist capsule. In cadavers in whom both capsules were collected, the limbs were compared. For the sake of comparison, the Wilcoxon matched pairs test was used. RESULTS Regarding statistical signifi cance, the largest share of the total circumference and area of the measured vessels of the dorsal capsule is constituted by the distal side (35.2% of the circumference and 30.9% of the area). The blood supply of the dorsal capsule received on the ulnar side is the lowest (12.9% of the circumference and 17.6% of the area). There was no signifi cant effect of age on vascularization of the dorsal wrist capsule confi rmed. Also, the comparison of vascularization of both limbs from a single cadaver did not yield any statistically signifi cant results. DISCUSSION Proximal row carpectomy is a long-established surgical technique used to manage the degenerative changes in the wrist. Our results showed the best vascularization on the distal and radial sides of the dorsal wrist capsule. In this light, the distally-based fl ap or the fl ap described by Berger, which respects the clinically important ligaments, appear to be the least invasive and help maintain the future stability of the wrist. CONCLUSIONS In clinical practice, we advise that a radially-based fl ap according to Berger is created and the distal side of the dorsal capsule, the most vascularized portion based on our results, is preserved as much as possible. The fl ap created in this manner also preserves the important carpal ligaments and appears to the authors of this study to be the most benefi cial, also with respect to the presence of the largest arteries, contrary to the distal side. Another option is to use a distally-based fl ap for interposition arthroplasty. Key words: interposition arthroplasty, proximal row carpectomy, vascularization, degenerative changes, wrist.

PURPOSE OF THE STUDY Extended lateral approach to calcaneus fractures is associated with a high risk of infection. Such risk can be reduced by using mini-invasive approaches. The sinus tarsi approach provides a good overview of the posterior joint facet of the calcaneus and can also be done as a mini-invasive procedure. The authors present their fi rst experience with osteosynthesis of joint depression calcaneal fractures using the anterolateral locking plate inserted through the sinus tarsi approach. MATERIAL AND METHODS During the period from 1 February 2020 to 31 January 2022, 18 patients were treated by the anterolateral locking plate in the authors' department (3 women, 15 men). Eleven fractures were classifi ed according to Sanders as IInd grade, fi ve as IIIrd grade and two fractures were classifi ed as tongue-type (as described by Essex-Lopresti). The fractures were treated by open reduction through the sinus tarsi approach and osteosynthesis by the anterolateral locking plate combined with headless screws. The following factors were examined: time from injury, duration of surgery, quality of reduction (post-op control with multiplanar CT scans), wound and technical complications, loss of reduction after treatment, substance abuse and comorbidities. The follow-up was 12-36 months (median 17). At one year after surgery, the functional outcomes were evaluated using the AOFAS Hindfoot score. RESULTS The most common negative predispositions for successful healing were smoking (9 cases), alcohol abuse, drug abuse, mild mental retardation, personality disorder, insulin-dependent diabetes and epilepsy (1 case each), hypothyreodism and bronchial asthma (2 cases each). The time from injury to surgery and duration of surgery surgery were measured. The quality of reduction was excellent in 12 patients (dislocation less than 1 mm), good in 6 patients (dislocation less than 2 mm), dislocation more than 2 mm was not present in the group. In one case, a revision surgery was performed because of screw malposition into the subtalar joint, delayed wound healing was observed in two cases. There was no case of deep surgical site infection or loss of reduction. The mean AOFAS score after one year was 85 points. The most common complaints were scar pain or discomfort. DISCUSSION The current studies on osteosynthesis of calcaneal fractures favor the sinus tarsi approach for its lower risk of wound-related complications compared to the extended lateral approach. The sinus tarsi approach requires the use of different osteosynthetic material than the conventional calcaneal plate. If a conventional locking plate is to be used, the surgical approach has to be modifi ed. In 2021, Wang et al. published an intermediate step leading to the reduction of early complications and the use of conventional locking calcaneal plate inserted through the sinus tarsi approach, with an additional incision. The sinus tarsi approach is used also when intramedullary nailing is performed, which is preferred by biomechanical studies evaluating the rigidity of osteosynthesis. However, when comparing nails and locking plates, the differences are insignifi cant. The use of anterolateral locking plates was presented by Xie et al., with results similar to those of our own group of patients. CONCLUSIONS The results of the followed-up group of patients confi rm low complication rate of the sinus tarsi approach as reported by current literature. At the same time, it provides good options for reduction even in complicated fractures. For successful osteosynthesis, the anterolateral locking plate with headless screws may be used. The incidence of post-operative complications is low even in high-risk patients. Adhesions of peroneal tendons can be treated with material removal and tissue release. They could be prevented by good physiotherapy. Key words: calcaneus, osteosynthesis, anterolateral plate, peroneal tendons, sinus tarsi approach.

PURPOSE OF THE STUDY This study aims to analyse a subpopulation of patients with severe haemorrhagic shock and a concurrent unstable pelvic ring fracture. MATERIAL AND METHODS This manuscript is a retrospective study of prospectively collected data on trauma patients over a period of 10 years, namely between 2010 and 2019. These patients, primarily (after injury) referred to the trauma centre of the University Hospital Hradec Králové, were diagnosed with an unstable pelvic ring fracture as a part of multiple injuries. RESULTS The total number of patients with a pelvic ring fracture and concurrent acute phase of decompensated haemorrhagic shock in the period from 2010 to 2019 was 112. After excluding 25 patients with AIS 4 and 5 (Abbreviated Injury Scale) severe head trauma and another two patients who died of late-stage SIRS (systemic infl ammatory response syndrome) complications, the group consisted of 85 patients. Subsequently, the subpopulation of patients "in extremis" evaluated by the study included a total of 22 patients with the baseline systolic pressure below 70 mm Hg and/or baseline haemoglobin level below 80 g/l. CONCLUSIONS Prior to the evaluation of this study population, our department had no single algorithm developed to treat such patients. Slow blood circulation stabilisation or death were usually associated with inadequate haemostatic algorithm. The patients leaving the operating room and being handed over to the ICU presented the signs of a decompensated shock. Oftentimes, the pelvis was merely stabilised, with no further intervention to stop the bleeding. The extraperitoneal pelvic packing was performed in very few cases only. The extravasation of contrast media during the initial CT scan does not necessarily have to be detected due to vasospasm or hypotension with reduced blood fl ow. In such cases, only the size of haematoma is a sign of arterial bleeding. It is also risky to rely solely on vasography when stopping the bleeding which will certainly fail to stop venous bleeding. However, venous bleeding always accompanies arterial bleeding. Stabilisation of both segments of the pelvis is essential to stop bleeding in haemodynamically unstable patients with a pelvic ring injury. It is followed by extraperitoneal pelvic packing and in the case of continuing haemodynamic instability also vasography, namely even if there is a negative fi nding of the initial CT scan or if no initial CT scan was performed. This procedure has become the core of our single haemostatic algorithm. Key words: pelvic ring injury, patients in extremis, haemostatic algorithm.

PURPOSE OF THE STUDY The purpose of this study was to minimize tourniquet-induced ischemia-reperfusion injury (IRI) in total knee arthroplasty (TKA) surgery using the remote ischemic preconditioning (RIPC) model, as well as to assess antioxidant balance with thioldisulfi de homeostasis (TDH). The secondary goal is to evaluate the impact of RIPC on TKA clinical outcomes. MATERIAL AND METHODS Patients in the ASA I-III group who underwent elective TKA were enrolled in this prospective, randomized, double-blind clinical research. TDH parameters were measured individually in groups with (Group I) and without (Group K) RIPC at the following times: preoperative (T0), right before the pneumatic tourniquet was opened (T1), 1 (T2), 6 (T3), and 24 (T4) hours after it was opened. In addition, at 3-hour intervals, the postoperative pain level was assessed using a visual analog scale (VAS). RESULTS This study included 60 cases (Group K; n=30, Group I; n=30). Both groups had equal native thiol, total thiol, disulfi de levels, disulfi de/native thiol, disulfi de/total thiol, and native thiol/total thiol ratios (p>0.05 for each). The change in native thiol, total thiol, and disulfi de values at T0 and T4 periods, however, was not statistically signifi cant for Group K (p=0.049, p=0.047, p=0.037, and p=0.217, p=0.191, p=0.220, respectively). At the 15th hour, VAS values in group I were considerably lower than in Group K (p=0.002). DISCUSSION This prospective, randomized, controlled trial examined how RIPC affected tourniquet-induced IRI-induced oxidative stress in TKA surgery. Lower native, total, and disulfi de levels at each postoperative time point were signifi cant. RIPC may reduce tourniquet-induced IRI-induced oxidative stress and TDH in TKA surgery. RIPC also reduced postoperative discomfort. CONCLUSIONS Our fi ndings suggest that RIPC may protect against the oxidative stress caused by IRI during limb surgery with a tourniquet and improve postoperative clinical outcomes. Key words: remote ischemic preconditioning, ischemia-reperfusion injury, thiol-disulfi de balance, oxidative stress, total knee arthroplasty.

PURPOSE OF THE STUDY Different techniques have been reported to reconstruct the defi cient acetabulum during total hip arthroplasty (THA). The purpose of this study was to compare the biomechanical features of the bulk bone graft (BBG) technique (Harris acetabular plasty) and the Roof Step Cut (RSC) technique using fi nite element analysis. MATERIAL AND METHODS Based on a female patient's dysplastic hip CT scan, 3D models were assembled according to the two techniques. For the Harris technique, an irregular BBG was sculpted from a solid sphere, while for the RSC technique, the graft was sculpted into a step-cut shape with a similar size. Each graft was fi xed with two compression screws at two different angles (0° and 45°). Four fi nite element models were used to compare the von Mises stress distribution and total deformation of the grafts and the screws. The pressure and sliding distances of the contacts between the bone graft, metal cup and acetabular host bone were also analyzed. RESULTS For both of the bone grafts and the screws, compared to the Harris models, the maximum stress of the RSC models was signifi cantly lower (16.56 MPa, 25.50 MPa vs 97.13 MPa, 112.72 MPa) and the total deformation was signifi cantly smaller (0.0096 mm, 0.0089 mm vs 0.022 mm, 0.018 mm). 45° inserted screws generated higher stress at the end of the screws and on the outside of the bone graft. In case of 0° inserted screws, the maximum value was mainly located in the middle of the screws, inside the screw channel as well as at the contact area between the graft and the host bone. At all analyzed contacts, the RSC technique shows signifi cantly lower pressure and sliding distances, irrelevant to the screw's insertion angle. In comparison, the model of BBG with 45° screws showed a signifi cant sliding effect and higher contact pressure. CONCLUSIONS Compared with the BBG technique, the step-shaped graft of the RSC technique could signifi cantly reduce the maximum stress and deformation of the graft and the screws, and decrease the pressure and sliding distance between the bone graft, metal cup and the acetabular host bone. The angle of screw placement affects the location of stress and deformation. Key words: developmental dysplasia of the hip, total hip arthroplasty, acetabular reconstruction, bone graft, fi nite element analysis.

The spleen is one of the most commonly injured organ in blunt traumas to the chest and abdomen. Splenic injury can be a serious complication of fracture of the left 9th to 11th rib. The authors present a case report of a 65-year-old male patient with a blunt trauma to the left chest and abdomen, diagnosed with multiple left rib fractures, left hemothorax and splenic injury with a small subcapsular hematoma with no signs of active splenic bleeding. Due to hemodynamic instability and a large volume of blood loss via the chest drain, the patient was indicated for emergency left thoracotomy. A perforation in the lower lobe of the left lung caused by rib fractures was found, which was treated with sutures. Furthermore, the diaphragm was examined, two ruptures were identified from which blood was coming out, and thus a phrenotomy was performed. The bleeding central splenic rupture came as a big surprise. A spleen preserving surgery was impossible, therefore a splenectomy had to be performed, followed by chest wall stabilization with splints. Transthoracic approach to manage the splenic injury through phrenotomy should not be used as a standard. In a selected group of patients with concomitant chest and upper abdominal organ injuries, the use of this surgical approach appears to be highly beneficial. Key words: splenic injury, splenectomy, thoracotomy, rib fractures, diaphragmatic rupture.

Acute traumatic intervertebral disc herniation of the thoracic spine is a rather rare injury with only a few reported cases to date. In this manuscript, we present a case of a 58-year-old male patient who sustained a car accident-related high-energy trauma, resulting in a disc herniation of the thoracic spine. Furthermore, we also discuss the possible implications of late diagnosis of such condition. The patient was initially referred from the Emergency Department as a case of head contusion with a left upper limb paresis. Due to only minimal bony trauma visible on the initial spine CT scan, the neurological deficit was attributed to the cranial trauma. The diagnosis of a traumatic disc herniation was therefore established only after the rapid onset of paraparesis, which gradually progressed into paraplegia, and a following spine MRI scan. Despite the subsequent urgent spinal decompression, the neurological functions of the lower limbs were not restored. This manuscript addresses the indications for performing MRI scans in polytrauma patients with a CT-verified spine trauma. Although it may be complicated to perform routine MRI scans in all such patients in daily practice, it can certainly help diagnose such injuries earlier and thus prevent potential permanent neurological damage to the patients. Key word: spine injury, traumatic disc herniation, thoracic spine, spine surgery.

PURPOSE OF THE STUDY Rhizarthrosis, a degenerative condition of the carpometacarpal joint of the thumb, affects mainly women. Surgical treatment is indicated once the non-operative treatment fails. Thumb carpometacarpal joint total arthroplasty constitutes one of the surgical treatment options. This study aims to evaluate the short-term functional and radiological outcomes of Touch® prosthesis with a minimum follow-up period, namely two years after surgery. MATERIAL AND METHODS The study presents the outcomes of a group of 56 endoprostheses implanted in 48 patients. The dual mobility Touch® prosthesis is evaluated. The group consisted of 41 women and 7 men, with the median age of the patients being 62 years. The patients were indicated for surgery after the non-operative treatment had failed. All of them suffered from stage II - IV osteoarthritis according to the Eaton-Littler classification. The range of motion - the opposition was assessed using the Kapandji score. The function and the pain were evaluated with the DASH questionnaire preoperatively and at 3 months, 6 months, 1 year and 2 years postoperatively. RESULTS After 24 months, 91.1% (51 patients) were satisfied with the surgical outcome. Altogether 8.9% of patients (5 patients) experienced postoperative exercise-induced pain, limitation of movement of the CMC joint or hand weakness. No dislocation or endoprosthetic loosening occurred in the evaluated group. Primary wound healing was reported in all patients and no superficial or deep infection was observed. The mean DASH score was 65.3 points preoperatively; at the 2-year follow-up, the mean score decreased to 10.8 points. The pain assessed in question 24 of the DASH questionnaire decreased from the mean value of 4.45 points to 1.2 points. After two years, the range of motion of all patients was X/X according to Kapandji. DISCUSSION There are plenty of surgical techniques to manage rhizarthrosis. All types of surgery have their pros and cons. Most endoprostheses used nowadays show good short-term, mid-term, and some of them even long-term outcomes in terms of survival. The Touch® prosthesis, characterized by dual mobility, is the 3rd generation thumb CMC prosthesis and in our study achives comparable short-term outcomes to those reported by international literature. The use of the dual mobility design appears to be effective in reducing the dislocation rate. CONCLUSIONS The Touch® thumb CMC prosthesis achieves very good short-term functional and radiological outcomes. We can recommend the prosthesis provided the patients are followed-up for more than two years after surgery. Key words: rhizarthrosis, osteoarthritis, endoprosthesis of the carpometacarpal joint, dual mobility, Touch®.

PURPOSE OF THE STUDY Articular cartilage injury is a common disease in daily life, with a high incidence. The aim of this study was to investigate the effect and mechanism of miRNA-140-3p in bone mesenchymal stem cells (BMSCs)-derived exosomes under hypoxia on inflammatory articular chondrocytes. MATERIAL AND METHODS To simulate the pathological status of arthritis, rat chondrocytes were used to establish the osteoarthritis (OA) model by IL-1β (10 μg/ml) as a modulating in vitro, and exosomes were isolated by differential ultra-high speed centrifugation. The cell counting kit-8, wound healing and flow cytometry assays were utilized to assess proliferation, migration and apoptosis of chondrocytes, respectively. Lipogenic and chondrogenic differentiation of chondrocytes were detected by oil red O staining and toluidine blue staining individually. The expressions of miR-140-3p and chondrocyte-specific gene mRNA were investigated using qRT-PCR. Western blot was applied to assess chondrocyte associated proteins and BMSC-Exo surface protein markers, and immunohistochemistry was adopted to detect the staining of collagen I and II. RESULTS Under scanning electronic microscope, the shape of exosomes was almost round. Exosome treatment prominently impaired the inhibition of chondrocytes' proliferative and migrative ability by IL-1β. It was found hypoxia had a more marked impact on proliferation, expression of collagen II and apoptosis in OA chondrocytes than normoxia, as well as a stronger effect on weakening adipose differentiation and enhancing chondrogenic differentiation in inflammatory chondrocytes. Furthermore, incubation with BMSC-Exo overexpressing miR-140-3p can remarkably increase the survival rate and migration in inflammatory chondrocytes. In addition, overexpression of miR-140-3p was found to enhance the chondrogenic differentiation of inflammatory chondrocytes. Furthermore, we found that the healing effect of exosomes on inflammatory chondrocytes under hypoxic conditions was produced by a rise in miR-140-3p expression within them and that hypoxia-mediated upregulation of miR-140-3p expression occurred through HIF-1α. CONCLUSIONS Under hypoxia, BMSC-Exo enhanced the chondrogenic phenotype, increased the viability of inflammatory chondrocytes. The overexpression of miR-140-3p in BMSC-Exo is beneficial to protect joints and delaying the pathogenesis in OA. Key words: HIF-1α, apoptosis, lipogenic differentiation, chondrogenic differentiation.

PURPOSE OF THE STUDY The current study aimed to investigate the intra- and inter-observer reliability of the Ellman classification system in partialthickness rotator cuff tears through magnetic resonance imaging (MRI) scans instead of arthroscopic views. MATERIAL AND METHODS Pre-operative MRI scans of 45 patients, with confirmed partial-thickness rotator cuff rupture in previous arthroscopic surgeries (performed by the senior author), were obtained from Picture Archiving and Communication Systems records. The observers (n=8) were asked to categorize MRI scans according to Ellman's classification of location and grade. There were four orthopedic surgeons less experienced in rotator cuff operations in the first group and four more experienced orthopedic surgeons in the second group. They were asked to re-evaluate the MRI scans six weeks later, without access to their previous answers. Reliability evaluation was performed within and among the groups. It was also evaluated if the surgeon's experience increased the reliability of the classification. Fleiss kappa coefficient was used for the inter-observer reliability and Cohen kappa coefficient for the intra-observer reliability, and post hoc analysis was performed. RESULTS When all observers were examined in the inter-observer evaluation, it was seen that there was moderate agreement in the first location evaluation (κ=0.414); however, there was fair agreement in all other evaluations in both groups (κ=0.339- 0.383-0.337, respectively). When all observers were examined in the mean intra-observer evaluation, it was seen that there was substantial agreement in both evaluations (κ=0.795-0.721, respectively). DISCUSSION A classification system must be valid, reliable, and reproducible. It should establish a standard terminology for both surgeons and researchers. The correct identification of the tear configuration is crucial for selecting the correct repair technique. In our study, in which we evaluated the Ellman classification, which is frequently used in arthroscopic diagnosis, we investigated its intra-observer and inter-observer reliability on MRI scans. Although the mean intra-observer evaluation results were substantial agreement (κ=0.795-0.721, respectively), inter-observer evaluation results were fair agreement (κ=0.339- 0.383-0.337, respectively) except for the first location evaluation (κ=0.414). CONCLUSIONS Although intra-observer reliability was satisfactory, the Ellman system used in the classification of partial-thickness rotator cuff tears was not found to be useful by using only MRI views because of fair inter-observer reliability except for the first location evaluation, which was moderate agreement. Key words: partial, rotator cuff, tear, Ellman classification, reliability, validity.

PURPOSE OF THE STUDY Total arthroplasty of the first metatarsophalangeal joint is one of the surgical treatment options for patients with advanced hallux rigidus. This study evaluates the pressure changes in the propulsion phase of the gait cycle using dynamic pedobarography after the total arthroplasty of the first metatarsophalangeal joint by Medin PH-Flex and their comparison with the control groups of patients with hallux rigidus and with asymptomatic patients. MATERIAL AND METHODS Dynamic pedobarograph was used to evaluate 15 first MTP joint replacements by Medin PH-Flex implants in 12 female patients, the average time since joint replacement was 3.5 years (1.5 to 5.5 years). The control group consisted of 13 forefeet in 12 patients with hallux rigidus of Grade 3 and Grade 4 according to the Coughlin classification and 17 healthy patients with no clear foot deformity, i.e. of a total of 34 forefeet. A zone for each metatarsal (M1-M5) and the big toe area (T1) were defined with the use of an integrated software. The difference between the pressure under the big toe area and the first metatarsal bone - hallux stiffness (T1-M1) and the forefoot balance parameter, i.e. the difference between the pressures under the medial and lateral half of the forefoot ((M1+M2)-(M3+M4+M5)), was obtained. The parameters were evaluated for each group during the propulsion phase of the gait, i.e. from 55% to 100% of the stance phase and from 75% to 100% of the stance phase, i.e. that part of propulsion when the greatest pressure is exerted on the big toe. RESULTS For the HS parameter (T1-M1) in 55% to 100% of the stance phase, the median value was -0.66 ± 1.22 (-1.90 to 1.45) in the control group, -0.85 ± 1.94 (-1.40 to 3.80) in patients with hallux rigidus, and -0.10 ± 1.48 (-1.30 to 2.40) in patients after the first MTP joint replacement. The median forefoot balance parameter from 55% of the stance phase was -3.48 ± 2.45 (-6.90 to 0.68) in healthy patients and -4.43 ± 2.72 (-6.98 to 0.23) in hallux rigidus patients. In patients after the joint replacement, the value was -3.00 ± 2.46 (-6.20 to 0.40). The data were statistically analysed by the Dunnett's and Tukey's multiple comparison tests. The hallux stiffness parameter showed a significant improvement after the joint replacement compared to patients with hallux rigidus (p<0.0001). No statistical significance was confirmed when comparing the joint replacement cases and the healthy patients from the control group (p=0.0007 and p=0.0010, respectively). As concerns the forefoot balance parameter, a significant difference was reported in patients with joint replacement compared to healthy patients from the control group and patients with hallux rigidus (p <0.0001). DISCUSSION The published pedobarographic studies differ in terms of the methodology used, the patient population and the parameters examined. The pedobarographic studies after the replacement of the first MTP joint or after its arthrodesis present inconclusive outcomes. According to the available literature, the joint replacement has the potential to improve mediolateral forefoot loading and to partially restore the weight-bearing function of the first ray. Our analysis of the HS parameter suggests that the MTP joint replacement can improve the big toe function compared to patients with hallux rigidus but fails to achieve the functional outcomes of healthy patients. When evaluating the forefoot balance (FB) parameter, we can observe less loading on the lateral half of the forefoot in the propulsion phase compared to hallux rigidus. Nonetheless, the joint replacement is unable to restore the physiological loading of the foot. CONCLUSIONS The first MTP joint replacement has the potential to improve forefoot function and to bring it closer to that of a healthy person, even though achieving physiological loading of the forefoot is unrealistic. Additional studies will be needed to confirm that the indication for the first MTP joint replacement is justified in hallux rigidus in terms of the effect on forefoot biomechanics. Key words: hallux rigidus, total replacement of the first MTP joint, dynamic pedobarography, footscan.

PURPOSE OF THE STUDY Dislocation is one of the most common early complications of total hip arthroplasty (THA). In this manuscript, 20 years of experience with the management of this complication are presented, particularly in relation to the type of instability. MATERIAL AND METHODS In the period between January 1999 and December 2020, at least one dislocation occurred in 157 of 8 286 (1.9%) THA patients, of which 117 dislocations (1.6%) in primary and 40 (3.4%) in revision THAs. Almost all patients were operated on from the anterolateral approach during the follow-up period. The type of dislocation was evaluated using the modified Dorr classification. In the first dislocations, conservative approach was usually opted for, except for cases with a clear malposition, irreducible or unstable hips after the reduction. The minimum follow-up period was 18 months (18-240). The success rate of the chosen treatment approach was assessed by means of standard statistical methods. RESULTS The total dislocation rate in the follow-up period was 1.6% for primary THAs and 3.4% for revision THAs. The dislocation rate was slightly higher between 1999 and 2009 compared to the following decade (2.1% versus 1.3% for primary THAs; p=0.009). The most common type of dislocation was the positional dislocation (62%), followed by dislocations due to a combination of causes (17%) and component malposition (11%). Treatment of dislocation was successful in a total of 130 patients (130/157; 83%). Even though a stable hip was achieved in 21 patients (13%), the functional outcome was unsatisfactory, and in 6 patients (4%) we failed to achieve a stable hip. In the positional type of dislocation, the success rate of closed reduction following the first-time dislocation was 86.4% and a similar success rate was reported for reoperations in the first-time dislocations due to the malpositioned components (85.7%). In the second-time dislocation, the surgical therapy was significantly more reliable compared to closed reduction regardless of the type of dislocation (78.6% versus 46%). The treatment of dislocations following primary THAs showed comparable outcomes to those of the treatment of dislocations following revision THAs. Overall, the worst outcomes were achieved in patients with a combined type of dislocation. In total, the THA had to be removed in 11.5% of hips (18/157). The probability of final THA removal increased with the increasing order of dislocation. DISCUSSION In our group of patients, the dislocation rate in THA was comparable or lower than the published data. With the use of preventive measures, i.e. dual mobility cup or larger head diameters in high-risk patients, we managed to reduce the dislocation rate over time. The positional type of dislocation prevails in our group of patients just as in the previously published series, followed by instability from malposition of components. The modified Dorr classification is used to guide the treatment since it allows us not only to make good decision about the treatment modality but to some extent also to estimate the final outcome, particularly with respect to restoring a functional and stable hip. CONCLUSIONS The total dislocation rate was 1.6% for primary THAs and 3.4% for revision THAs. The first-time dislocation of the positional type shall be treated conservatively. Conversely, in the other types of dislocations and in recurrent dislocations, surgical treatment is more likely to achieve a good clinical outcome. The worst outcomes are to be expected in an instability due to combination of multiple causes, which leads to the removal of THA more often than in other types of dislocations. Also, the benefit of preventive measures in high-risk patients over time has been confirmed. Key words: total hip arthroplasty, dislocation, Dorr's classification, treatment strategy, outcomes, complications.

PURPOSE OF THE STUDY A global bibliometric comparison of the level of scientific interest and output in the two research areas hip and knee arthroscopy (H-ASC and K-ASC) was carried out. In addition, the different degrees of publication activity in the countries and institutes performing this research were investigated. MATERIAL AND METHODS Publications from 1945-2020 listed in the Web of Science Core Collection were included in the study. Using the web application Science Performance Evaluation (SciPE), quantitative and qualitative aspects were evaluated. Subsequently, the date of publication, author information, and other metadata were analysed. RESULTS Since 1945, 3,924 studies have been published on K-ASC and 2,163 on H-ASC. The majority of the publications which have appeared since 2016 dealt with the topic of H-ASC (H-ASC: 241.2 publications/year; K-ASC: 217.4 publications/year). The USA published the most on both topics (H-ASC: 1,123 publications; K-ASC: 1,078 publications). More countries and institutes participated in K-ASC (3,008 institutes, 82 countries) than in H-ASC (103 institutes, 57 countries). The ten institutes with the most publications accounted for 36.71% and 12.34% of all publications on H-ASC and K-ASC, respectively. H-ASC received 78.12% of its funding from private sponsors while K-ASC was supported mainly by governmental/nonprofit sponsors (70.92%). CONCLUSIONS This study provides the first scientific comparison between H-ASC and K-ASC. Measured by qualitative and quantitative aspects, K-ASC was the most flourishing research area overall. In the last ten to five years, interest has shifted towards HASC with an increasing number of publications and a higher rate of citations.

PURPOSE OF THE STUDY The study aims to determine the incidence of fracture-related infection (hereinafter referred to as the FRI) at a Level I trauma centre over a three-year period. It also aimed to determine the risk factors, to observe confirmatory and suggestive criteria in line with the applicable recommendations, and to evaluate the bacterial spectrum in a diagnosed FRI. MATERIAL AND METHODS It is a retrospective-prospective study carried out through studying the documentation. The study included all patients diagnosed with FRI and treated between 2019 and 2021, except for the patients with hand fractures since minor phalangeal fractures of the fingers were largely treated by the outpatient department, no osteosynthesis was performed in the operating room, and these patients were not followed up at our department. RESULTS The FRI incidence was 2.33% of all osteosyntheses performed at the Level 1 trauma centre in the period 2019-2021. The FRI was most often caused by pyogenic cocci agents and the FRI developed most frequently within 6 months after osteosynthesis. The site at risk was the lower limb region. The FRI incidence was most often indicated by suggestive clinical criteria (redness, secretion, pain) and radiological criteria (delayed healing, non-union). Overall, 42.19% of treated nonunions were later diagnosed as FRI. At the time of FRI diagnosis, the CRP values were normal in 21.7% of patients. DISCUSSION The FRI incidence rate in 2019-2021 was 2.33%, which corresponds with the values reported in other papers focusing on the incidence of infectious complications after osteosynthesis. Fang and Depypere reported 1-2% of infectious complications. The most common risk factors are open fractures, which account for 20.16% in our cohort. Ktistakis and Depypere describe the incidence of osteomyelitis in 30% of treated open fractures. In our cohort, the incidence of FRI was significantly higher in lower limb fractures. Bezstarosti, Wang and Pesch published similar results, with some deviations. The time from osteosynthesis to final FRI diagnosis varied from a few weeks to several years. In more than half of the patients the FRI developed within 6 months after performed osteosynthesis. Metsemakers and Fang refer to the very same trend. The CRP levels in the study population varied a lot. Xing-qi Zhao describes CRP as a less sensitive (sensitivity 65.6%) but more specific marker (specificity 75.4%). According to the available literature, the most common agents causing infectious complications of osteosynthesis are gram-positive cocci, S. aureus in particular. In our study, G+ pyogenic cocci were clearly the most commonly detected, which is consistent with the results of studies by Fang and Depypere, focused on the incidence of infectious complications. The most common FRI clinical manifestations included wound secretion, redness, swelling and pain. Furthermore, suggestive radiological criteria, especially delayed healing and non-union also indicated the FRI occurrence. According to Fang, the most common clinical manifestations of infectious complications include pain, swelling, redness and wound dehiscence. Fang reports that the most common radiologic findings are the periosteal reaction, loosening of the implant and delayed healing or non-union, which is consistent with our cohort. In the cohort of non-unions surgically treated at our department, FRI was subsequently confirmed in 42.19% of cases. CONCLUSIONS The incidence of FRI at Level 1 trauma centre was 2.33% of operated fractures in 2019-2021, with pyogenic cocci being the most common infectious agents. The FRI usually developed within 6 months after osteosynthesis. The typical site for the FRI development was the lower limb region, the ongoing FRI was indicated by suggestive clinical criteria (redness, secretion, pain) and radiological criteria (delayed healing and a non-union). Overall, 42.19% of treated non-unions were later diagnosed as FRI. Key words: fracture-related infection, FRI, suggestive criteria, confirmatory criteria, FRI diagnosis, microbial, microbiology spectrum, osteosynthesis, complications, non-union.

PURPOSE OF THE STUDY Patellofemoral stability and congruency are influenced by different parameters. Their contribution to anterior knee pain and instability is not fully understood. We investigated, if isolated femoral antetorsion of more than 25° leads to patellofemoral instability. MATERIAL AND METHODS We analyzed 90 knees in patients with patellofemoral complaints and correlated clinical and radiological characteristics. Patients presenting at our center between January 2018 and December 2020 because of patellofemoral pain or instability were included, provided that there was no previous surgical intervention done. RESULTS The severity of trochlea dysplasia classified using the Oswestry-Bristol classification significantly correlated with events of patellofemoral dislocations. (χ=8.152, p=0.043, φ=0.288). All males with a history of patella dislocation had at least a mild trochlea dysplasia. The majority of females complaining about patellofemoral symptoms in general had a dysplastic trochlea. Patella alta is more frequently found in patients with trochlea dysplasia than in patients with a normal femoral trochlea anatomy. DISCUSSION The majority of unstable patellofemoral joints showed a dysplastic trochlea. A high femoral antetorsion was found to be an additional minor factor contributing to instability. Isolated high femoral antetorsion without trochlea dysplasia rather leads to anterior knee pain without patella dislocation. Furthermore, no direct significant correlation between patella alta and patellofemoral instability was found. Patella alta can therefore rather be seen as a result of a dysplastic trochlea than a primary major risk factor for patellofemoral instability. CONCLUSIONS Trochlea dysplasia is the major risk factor for patellofemoral instability. Patella alta can rather be seen as a result of a dysplastic trochlea than as a primary risk factor for patella instability or pain. Isolated high femoral antetorsion often leads to patellofemoral pain syndrome but not to patella dislocations. Key words: MPFL, patella instability, patellofemoral instability.

PURPOSE OF THE STUDY Although there are numerous studies on outcomes and comparison of open and closed reduction but there is no clarity on relationship between outcomes and complications with type of surgical intervention done for Type 3 Gartland supracondylar humerus fracture. The aim of this study is to compare the outcomes and complications of closed vs open reduction in Type 3 Gartland supracondylar humerus fractures. MATERIAL AND METHODS Electronic literature searches of Embase, MEDLINE and the Cochrane Library was conducted in February 2022 using the terms "supracondylar", "humerus", "fracture", "Gartland type 3" and synonymous. The data extracted included the study details, demographic data, procedure performed, final functional and cosmetic outcome according to Flynn criteria and complications of included studies. RESULTS Pooled data analysis revealed no significant difference in mean satisfactory outcome rate according to Flynn cosmetic criteria in open group (97%, 95% CI 95.5%-98.5%), as compared to closed group (97.5%, 95% CI 96.3%-98.7%), although a statistically significant difference in mean satisfactory rate according to Flynn functional criteria in open group (93.4%, 95% CI 90.8%- 96.1%) as compared to closed group (98.5%, 95% CI 97.5%-99.4%) was noted. On separate comparison of the two-arm studies, closed reduction favoured better functional outcomes (RR 0.92, 95% CI 0.86-0.99). CONCLUSIONS Closed reduction and percutaneous fixation have better functional outcome than open reduction with K-wire fixation. But there was no significant difference in cosmetic outcomes, overall complication rate and nerve injury with either open or closed reduction. The threshold of converting a closed reduction to an open reduction in supracondylar humerus fractures of children should be high. Key words: supracondylar humerus, open reduction, percutaneous pinning, Flynn criteria.
