Lateral instability of the knee is less frequent but more disabling than medial instability of a comparable amount. At the same time the diagnostic tests for lateral instability are more subtle and more frequently misinterpreted. Posterolateral rotatory subluxation is demonstrated by an apparently positive posterior drawer test with the tibia in neutral rotation or by the external rotation-recurvatum test with the knee in extension. Anterolateral rotatory subluxation is present when the anterior drawer test with the tibia in neutral rotation demonstrates that the lateral tibial condyle appears to become more prominent or that both condyles appear to become equally prominent.

Using monitoring and simulation to analyze the failure characteristics of multizone landslides controlled by faults: a case study.

Slopes influenced by multiple faults are prone to large-scale landslides triggered by multi-regional failures. Understanding the failure process and sequence is essential for the sustainable development of mining operations. This paper presents a method combining InSAR monitoring and numerical simulation to analyze the failure processes of slopes affected by multiple faults.

Background: Recurrent shoulder dislocations often lead to multiple encounters for reduction and eventual surgical stabilization, both of which involve exposure to opioids and potentially increase the risk of chronic opioid exposure. The purpose of our study was to characterize shoulder instability and compare pre- and post-reduction opioid usage in singular dislocators (SD) and recurrent dislocators (RD).
Methods: This retrospective study was performed at a single academic institution using a prospective database.
Comparison of Interportal and Periportal Capsulotomies and Axial Distraction Resistance During Hip Arthroscopy: An In Vivo Propensity-Matched Cohort Study.

Department of Orthopaedics, University of Utah, Salt Lake City, Utah, USA.
Background: Intraoperative hip capsule management is increasingly recognized as an important component of hip arthroscopy for the prevention of capsular-related instability. The periportal capsulotomy, relative to the interportal capsulotomy, has been proposed as a minimally invasive technique for decreasing postarthroscopy hip instability; however, the biomechanical effects of this technique are not well established.
Purpose/hypothesis: This study aimed to provide a biomechanical characterization of interportal and periportal capsulotomies, helping inform surgeon choice of capsulotomy type and repair, potentially guiding clinical practice in hip arthroscopy.

: Spontaneous chest wall hematomas are rare but potentially life-threatening complications, particularly in patients with multiple comorbidities such as those undergoing hemodialysis. This case report aims to highlight the significance of early diagnosis and appropriate management in preventing complications associated with this condition. : We report the case of a 79-year-old man with end-stage renal disease on hemodialysis, presenting with a large spontaneous hematoma (18.

: Multiligament knee injuries, involving damage to multiple stabilizing structures, present a significant challenge in orthopedic surgery, often resulting in knee instability and compromised function. While anatomic ligament reconstruction has been traditionally advocated, non-anatomic techniques may provide effective alternatives, particularly for patients with moderate functional demands who do not require high-level athletic performance. : In this study, we assessed the outcomes of a non-anatomic, hybrid surgical approach involving combined arthroscopic and open non-anatomic ligament reconstruction in 60 patients with multiligament knee injuries.
