High tibial osteotomy (HTO) is used in the treatment of knee osteoarthritis. This surgical procedure is indicated in patients with medial osteoarthritis who are relatively young and active and have a good range of motion. In most medial open-wedge HTO cases, the fascia, medial collateral ligament (MCL), and part of the knee joint capsule are carefully separated and moved to expose the osteotomy site, but many patients experience postoperative swelling and pain in the affected limb due to bleeding from the osteotomy site and MCL failure. We have developed a method of osteotomy followed by a restoration of the MCL to its anatomic position and complete soft-tissue coverage of the osteotomy. This Technical Note aims to provide a comprehensive description of the employment of a soft-tissue envelope for the MOW-HTO protection.

Department of Orthopaedic Surgery, University of Nebraska Medical Center, Omaha, Nebraska, USA.
Purpose: This study aims to characterize the mechanism of multi-ligament knee injury (MLKI) sustained during a National Football League (NFL) game through video analysis.
Methods: A retrospective video analysis of official NFL game footage spanning 1997-2022 was performed. Players with MLKIs were identified from publicly available injury surveillance data.

Department of Orthopaedic Surgery & Trauma, Máxima Medical Centre, Eindhoven-Veldhoven, the Netherlands.
Purpose: This study aimed to determine the most reliable and precise method for measuring the buckling phenomenon of the posterior cruciate ligament (PCL) in skeletally immature patients on magnetic resonance imaging (MRI). The posterior cruciate ligament (PCL)-line sign, PCL angle (PCLA), PCL inclination angle (PCLIA) and PCL-posterior cortex angle (PCL-PCA) were considered. Secondary aims were to (1) compare PCL buckling between healthy and ACL-injured patients to establish a discrimination threshold, (2) assess its validity against other MRI parameters.

Background: Between 1.7 and 3 million sports-related concussions occur every year. While most concussion symptoms resolve within 3 weeks, the absence of biomarker-based tests makes evaluating return to sport difficult.

Background: Indications for stabilization of the medial collateral ligament (MCL) after repair of the lateral ulnar collateral ligament (LUCL) remain controversial. Here, we propose a standardized fluoroscopic sequence to reveal residual medial elbow instability to facilitate intraoperative decision-making.
Methods: Eight matched cadaveric upper extremity pairs (N = 16) were mounted to simulate intraoperative positioning.

Background: Multiligament knee injuries (MLKIs) often result from high-energy trauma in polytrauma patients. They may coincide with other musculoskeletal injuries, especially fractures of the ipsilateral lower extremity (LE) or pelvis. Understanding these fracture patterns can guide surgical planning and improve patient outcomes.
