Descriptive Study of Multiligamentary Reconstruction of the Knee

Evaluation of clinical results and postoperative laxity after single-stage reconstruction of multiligamentous lesions of the knee. Comparison of two types of transplant: allograft versus autograft. There is currently little data in the clinical outcome literature after allograft reconstruction. There is one study reporting postoperative laxity assessed by dynamic radiography in the four planes (anterior, posterior, varus, valgus). No study compares postoperative laxity after allograft versus autograft reconstruction.

External vs Combined Focus Effects on Landing in Female Athletes

Female athletes are at higher risk of knee injuries, particularly non-contact anterior cruciate ligament (ACL) injuries, often caused by dynamic knee valgus during landing. Proper landing techniques and neuromuscular training are crucial for injury prevention. Attentional focus strategies, such as external focus (EF) and internal focus (IF), can influence movement patterns, muscle activation, and skill transfer during landing tasks. EF generally promotes safer and more controlled landings, while IF offers certain kinematic benefits. However, real-world sports often require a combination of attentional strategies, and the effects of combined EF + IF instructions on landing mechanics and muscle activation have not been fully studied. This study will investigate the effects of EF and combined attentional focus instructions on lower extremity and trunk movement, muscle activation, and skill transfer in young female athletes with asymptomatic dynamic knee valgus. The investigators aim to determine whether combined attentional focus training provides greater improvements in landing mechanics, muscle activation, and skill transfer than EF training alone.
