Summary: This study collates data on the material properties of the four major knee ligaments in humans and investigates the influence of age and osteoarthritis (OA) on these properties. The results show significant negative correlations between age/OA and certain ligament mechanical properties. This research contributes to a better understanding of the pathophysiology of knee joint diseases.

Summary: This study quantified the in vivo elongation patterns of collateral ligaments during functional activities, revealing distinct patterns for different ligament bundles and subjects. The findings suggest that single-bundle reconstruction techniques may not fully restore healthy ligament function, and indicate greater varus laxity in the loaded knee.

Summary: This study aimed to evaluate the effects of partial and complete release of R-LCL on radiocapitellar joint stability under controlled varus load and progressive soft tissue release. The results showed significant changes in varus joint angulation after each release, with the angulation still affected by varus load post-release.

Summary: This study analyzed baseball pitchers with partial ulnar collateral ligament (UCL) tears using stress ultrasonography and investigated the impact of tear location on elbow joint stability. The results showed no association between tear location and ulnohumeral joint gapping.

Summary: The study aimed to develop a tool for classifying the severity of structural tissue damage in ACL injured knees. The ACL Injury Severity Scale (ACLISS) provides a simple description and categorization of a wide range of injuries in patients undergoing primary ACL reconstruction. The scale allows for the identification of different injury severity profiles.

Summary: Renewed interest in the lanthanide contraction arises from its potential impact on the properties and applications of Ln(III) compounds, as well as the associated theory. To comprehend this effect, understanding the normal relationship between contraction and the number of 4f electrons (n) is crucial. Recent data on ionic radii demonstrate a linear dependence on n for coordination numbers (CNs) of 6, 8, and 9, following the normal trend. Deviations from this trend suggest the influence of other interactions in the system. The suggestion of a curved variation fitted by a quadratic function has gained popularity in recent years.

Summary: The study investigated the relationship between the coronal LCL sign and knee laxity measurements, finding that the LCL sign on MRI was not associated with clinical knee laxity evaluations, regardless of age groups.

Summary: This study used a practical positional MRI protocol to evaluate tibiofemoral translation and rotation in normal and injured knees. The results showed that ACL tear knees exhibited increased tibial anterior translation and decreased external rotation compared to normal knees. Multidirectional malalignment was more common in ACL tear knees.

Summary: This study aimed to evaluate the outcomes of distal superficial medial collateral ligament (sMCL) release during opening-wedge high-tibial osteotomy (OWHTO), and the results showed that sMCL release did not cause valgus instability or valgus overcorrection at 1 year postoperatively. The clinical outcomes improved at the final follow-up compared with the preoperative status after OWHTO with sMCL release.

Summary: The study revealed that in ACL-injured patients, a preoperative grade III PS was mainly associated with a higher amount of intra-articular soft-tissue damage and chronicity of the injury. Patients with complete chronic ACL injuries and bimeniscal tears were more likely to have a preoperative grade III PS than their acute counterparts. This suggests that grade III PS may be an early sign of knee decompensation of dynamic rotational knee laxity in chronic ACL-injured knees with bimeniscal lesions.

Summary: This study identified age, body mass index, knee laxity, knee strength, and passive knee alignment as risk factors for non-contact ACL injuries. Among these factors, age, passive knee extension, and weak hamstring strength were associated with a higher risk, while passive knee valgus was specifically identified as a risk factor for women. These findings suggest that hamstring strengthening exercises could be beneficial in preventing ACL injuries in young male athletes or individuals with knee laxity.

Summary: This cadaveric study aimed to investigate the impact of anterolateral ligament (ALL) and anterolateral capsule (ALC) injuries on knee laxity with preserved iliotibial band (ITB) in anterior cruciate ligament (ACL)-injured knees. The results showed that injuries to ALL and ALC had a synergistic effect on knee laxity in terms of internal rotation, anterior translation, and varus angulation in ACL-injured knees.
