Conventional techniques, including the induced membrane technique, bulk allograft reconstruction, bone transport, and acute shortening, have inherent limitations. The advent of custom 3 dimensional printed implants has expanded reconstructive options, particularly in foot and ankle surgery. Patient-specific implant design enables more precise management of complex bone defects. Although long-term clinical data are limited, early outcomes are promising.

New technologies in the foot and ankle specialty are growing, but most studies and practice applications are in their infancy. Patient-specific instrumentation is the most successful use of new technology in foot and ankle. Research models and clinical applications of artificial intelligence in the field of foot and ankle are becoming more common, but studies are still lacking.

While robotic applications for orthopedic surgery are well established in arthroplasties, their use in soft-tissue surgery remains limited. This study presents the indications, technique, and clinical outcomes of robotic-assisted latissimus dorsi tendon transfers for shoulder reconstruction. The robotic approach allows accurate identification of the axillary and radial nerves, minimal soft-tissue trauma, reduced bleeding, and excellent cosmetic outcomes. The system's motion scaling and tremor filtration enhance precision. Robotic-assisted shoulder surgery is a safe and minimally invasive technique for tendon transfers around the shoulder.

Although most existing literature details lower extremity application, BFRT has shown beneficial effects on muscle hypertrophy, endurance, and strength in the upper extremity with a safe side-effect profile. Developing a universal protocol for upper extremity BFRT is challenged by the current lack of research, but it shows promise in playing a pivotal role in the rehabilitation and recovery of injured and postoperative patients across many populations.

Anatomic models are easily produced from standard imaging. Patient-specific prints for surgical planning, cutting guides, and durable medical equipment now can be produced in-house. Custom patient-specific instrumentation and even implants are now routinely available through commercial suppliers. Advantages include decreasing operative time, reducing radiation exposure, and limiting complications in complex cases. Operating-room savings can easily offset the capital cost of printers. This review explores the current landscape of 3D printing for patient care in orthopedic surgery and guidance on a path toward hospital-based point-of-care printing.

Anatomic models are easily produced from standard imaging that can enhance teaching opportunities, patient education, and complex surgical planning. For a surgeon, printing their own models can seem out of reach for numerous reasons. This review helps orthopedic surgeons understand the technology underlying 3D printing and how to get started making their own 3D prints of patient imaging data for teaching, patient education, surgical planning, and research.

Pulsed electromagnetic field, capacitive coupling, combined magnetic field, direct current, and low-intensity pulsed ultrasound modalities have been shown to accelerate healing in acute and chronic cases, reducing complications in high-risk patients. Supported by clinical trials, these devices offer noninvasive and invasive options to improve outcomes and lower costs. Recommendations emphasize integration into trauma protocols, with future directions exploring combined therapies.

The learning curve remains poorly defined for fellowship-trained surgeons who were trained primarily in MA. Current evidence demonstrates that fellowship-trained MA surgeons can achieve proficiency comparable to experienced KA surgeons after 30 to 40 cases. Our institution documented the learning curve of a fellowship-trained MA surgeon's adoption of calipered KA using manual instrumentation along with 12 month patient-reported outcomes for comparison. Future studies can determine evidence-based guidelines.

Applications of wearable smart devices range from activity and motion tracking to real-time monitoring of vital signs and biochemical markers. Recent evidence provides support for the use of wearable devices in chronic disease management, rehabilitation, and perioperative care of patients with total knee arthroplasty. Data derived from these devices may enhance treatment personalization and early identification of complications. Challenges remain regarding accuracy, standardization, privacy, and patient adherence. Future advances must overcome these limitations.

We present a case series of 8 adult patients with iliac crest/proximal gluteal pathology (6 degenerative, 1 posttraumatic, and 1 neoplastic) that highlights diagnostic challenges in this region. Our cases demonstrate the utility of musculoskeletal ultrasonography in both diagnosis and treatment of iliac crest enthesopathy. After reviewing relevant literature, we describe a novel ultrasound-guided surgical approach used in 5 patients in whom conservative therapies failed. This technique offers a minimally invasive alternative for managing recalcitrant iliac crest enthesopathy.

This procedure aims to reduce the bony prominence at the heel and to relieve Achilles tendon impingement to improve function and decrease pain. Recent innovations in minimally invasive/percutaneous approaches have enhanced outcomes while minimizing complications. Clinical and radiographic evaluation aids in diagnosis and surgical planning. Literature consistently demonstrates improved pain scores, functional outcomes, and high patient satisfaction following Zadek osteotomy.

Current options for surgical management include silicone, pyrocarbon and resurfacing arthroplasties, or interposition techniques. While overall many patients have improved pain and some function with current modalities, there are many complications. We describe a novel technique for MCP arthroplasty utilizing a custom acellular dermal allograft implant, which we believe to have properties that can improve implant failure rates. We describe a case for proof of concept of our technique and discuss its potential for improved hand function and pain relief, particularly in higher demand patients.

These conditions generally respond well to conservative management with medications, bracing, and corticosteroid injection. However, surgery should be offered during pregnancy if nonoperative treatment fails. Regional and local anesthesia decreases fetal anesthetic exposure, minimizes airway issues, and assists postoperative pain control. Pregnant patients with trauma should be evaluated for extremity injury, and appropriate imaging should be obtained while minimizing pelvic radiation exposure. Surgical management should include fixation techniques with minimal radiation exposure.

This article reviews the current applications, outcomes, workflow, and regulatory context for 3D technology in pediatric orthopedics. We also present a case demonstrating successful ankle reconstruction using 3D-printed PSI in a child with severe tibial deformity. With growing evidence and implementation, 3D planning is already becoming integral to pediatric limb reconstruction.

Total hip arthroplasty is a well-accepted option for posttraumatic arthritis in the setting of previously treated acetabular fractures. However, the incidence of acetabular fractures continues to increase in the aging population. This poses challenges including osteoporosis and the emphasis on early mobilization. Questions remain regarding the major differences in outcomes of delayed total hip arthroplasty versus acute "fix-and-replace." This review aims to compare outcomes between these treatment algorithms for displaced acetabular fractures.

Adequate exposure is needed to execute the planned arthroplasty. An algorithmic approach should be utilized to assist in the exposure of knees with a limited range of motion. This approach offers a stepwise sequence, with successive maneuvers indicated by the need for further exposure: medial parapatellar arthrotomy with wide synovectomy, quadriceps snip, then tibial tubercle osteotomy. The V-Y turndown, femoral peel, and "banana peel" are historical techniques not routinely utilized as part of the exposure sequence.
