Aim: The main aim of this study is to compare the gap arthroplasty with interpositional gap arthroplasty for the management of TMJ ankylosis.
Methodology: A prospective randomized multicenter clinical trial had been performed, on 60 patients diagnosed with TMJ ankylosis from August 2005 to June 2015. Patients were equally divided into two groups: Group I patients were treated with gap arthroplasty, while patients in Group II were treated with interpositional arthroplasty.
Results: The mean age in Group I was 27.9 years and in Group II was 25.6 years. Trauma was the common etiological factor in both the groups. The mean postoperative mouth opening after 1 month, 6 months and 24 months was found to better in Group II. Open bite after 24 months was present in six patients in Group I and in one case in Group II. Permanent facial nerve palsy was present in one patient in both the groups. Frey's syndrome was present in one patient from Group I and none from Group II. Reoccurrence occurred in eight cases from Group I (26.6%) and none from Group II.
Conclusion: This study concluded that interpositional arthroplasty is better than gap arthroplasty in terms of mouth opening and reankylosis.

Foreign Body Entrapment on the Bearing Surface in Total Hip Arthroplasty: A Report of Three Cases.

Total hip arthroplasty (THA) is a highly effective surgical intervention for end-stage hip joint disorders. While common complications such as infection, dislocation, and prosthetic loosening are well-documented, rarer complications remain underreported. One such complication is foreign body interposition on the bearing surface, which can compromise joint mechanics and adversely affect outcomes.

Purpose: In functionally aligned (FA) total knee arthroplasty (TKA), femoral component rotation (FCR) is personalised to optimise flexion gap balance. As axial malalignment has been attributed to patellofemoral complications, this study assessed FA FCR in relation to the surgical transepicondylar axis (TEA) and early implant survivorship.
Methods: We analysed 446 robotic-assisted primary TKAs in 393 patients using FA with preresection gap balancing.

Methods: Design: Retrospective cohort study.
Setting: National all-payer claims database.
Utilization of Total Knee Arthroplasty in the United States by Settlement Type: Is There Equity of Access?
J Am Acad Orthop Surg

From the Department of Orthopedic Surgery, Cleveland Clinic Foundation, Cleveland, OH (Huffman, Khan, Pasqualini, Rullán, Walsh, and Piuzzi), the Department of Orthopedic Surgery, Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, Cleveland, OH (Oyem and Runsewe), and the Orthopaedic Institute Brielle Orthopaedics, Division of Adult Reconstruction, Manasquan, New Jersey (Siddiqi).
Introduction: Total knee arthroplasty (TKA) is one of the most commonly performed orthopaedic surgeries in the United States, yet little information exists regarding its utilization in different settlement types. This study aimed to determine the number of TKA-performing surgeons by settlement type and assess trends in the volume of TKAs in urban, micropolitan, small town, and rural settings.
Methods: Using the Medicare Provider Utilization and Payment Data: Physician and Other Practitioners database, the number of orthopaedic surgeons performing primary and revision TKAs from 2013 to 2020 was determined.

Purpose: Gap-balanced total knee arthroplasty (TKA) technique relies on initial ligament evaluation, particularly in patient-specific implantation using computer-assisted technologies. This cadaveric study aimed to compare the reproducibility and reliability of medial and lateral gap measurements between manual stress testing and dynamic ligament balancer.
Methods: Initial gap acquisitions were assessed from eight cadaveric knees (four specimens) during the same navigated TKA procedure by five differently skilled surgeons (three seniors and two juniors).
