Objectives: The aim of this study was to identify the biomechanical and histopathological changes of ligamentum mucosum (LM) in patients with intact versus ruptured anterior cruciate ligament (ACL).
Patients And Methods: A total of 67 patients (45 males, 22 females; mean age: 33.2±7.9 years; range, 18 to 45 years) who underwent arthroscopic knee surgery for intraarticular pathologies between July 2022 and January 2023 were prospectively analyzed. The patients with LM were divided into two groups as the ACL intact group (n=31) and ACL ruptured group (n=36). Biomechanical tests and histopathological examinations were performed in all LM patients.
Results: Age and body mass index distributions were similar between the groups (p>0.05). Peak force values of the LM in the ACL ruptured group were significantly higher than the ACL intact group (p=0.037). No significant difference was found between the groups in terms of collagen index (p=0.103) and fibroblast count (p=0.821).
Conclusion: The peak force values of the LM were significantly higher in the ACL ruptured group as compared to the ACL intact group, which is probably due to the adaptation of LM in patients with ACL rupture against increased deforming forces to maintain knee stability.

There remains considerable debate regarding the optimal management of anterior cruciate ligament (ACL) injuries in skeletally immature patients. This study aims to evaluate the clinical outcomes of transphyseal ACL reconstruction in patients with open growth plates. This retrospective study included skeletally immature patients with full-thickness ACL tears and confirmed open physis.

Introduction: Recent advancements in surgical techniques have led to renewed interest in ACL repair, particularly for acute, proximal tears. Suture tape augmentation (STA) has emerged as a promising technique to support ACL healing while preserving native tissue and potentially improving outcomes. This study aims to evaluate the outcomes of ACL repair with STA in patients with acute, proximal ACL tears.

Objective: The influence of the graft sagittal inclination angle (SIA) on knee stability, biomechanics, and graft maturity has been elucidated. However, no study has comprehensively described the effects of SIA on the aforementioned postoperative prognostic indicators. So, we aimed to determine whether the sagittal inclination angle (SIA) of a graft is associated with postoperative graft maturity, joint stability, and joint function after anterior cruciate ligament (ACL) reconstruction.

Background: To compare knee laxity between the conventional round tunnel and oval tunnel techniques in primary anterior cruciate ligament (ACL) reconstruction in a porcine knee model.
Methods: Twenty porcine knees were used for evaluating laxity in terms of anterior translation and anterolateral rotation. The study determined porcine knee kinematics on the Instron instruments under simulated Lachman (89 N anterior tibial load) at 15°, 30°, and 60° of flexion and a simulated pivot shift test (89 N anterior tibial load, 10 Nm valgus, and 4 Nm internal tibial torque) at 30° of flexion.
Over the past 15 years, there has been a shift toward meniscus preservation even for previously believed irreparable patterns like bucket handle, radial, meniscus root, vertical, and horizontal cleavage tears (HCTs). HCTs are a common tear pattern, especially as we age, and are estimated to occur in 23% to 32% of meniscus tears. They occur in both males and females, are more common on the medial than the lateral side, and most often occur with minor to normal trauma in an anterior cruciate ligament intact knee.
