Sex-based disparities in the anterior cruciate ligament (ACL) injury risk may be partly explained by cyclic variations in sex hormones that drive systemic shifts in tissue osmoregulation. Ultrashort echo time (UTE) T2^* magnetic resonance imaging provides a noninvasive, quantitative means of evaluating the water content...

Long-term studies are emerging reporting encouraging outcomes after matrix-induced autologous chondrocyte implantation (MACI). While MACI has historically been undertaken via open arthrotomy, arthroscopic techniques have been reported. However, longer term clinical outcomes and/or graft survivorship after...

While coronal malalignment influences outcomes after medial meniscus posterior root tear (MMPRT) repair, alignment parameters such as the hip-knee-ankle angle (HKAA) may not fully capture the biomechanical setting of the medial compartment. The joint line convergence angle (JLCA) reflects the intra-articular...

Posterior tibial slope (PTS) is a well-established anatomic risk factor for anterior cruciate ligament (ACL) graft failure. Lateral extra-articular tenodesis (LET) is increasingly used as an adjunctive procedure in high-risk patients to reduce rerupture rates; however, how its protective effect varies across the...

Previous literature has demonstrated that an increased number of preoperative anterior shoulder instability episodes is associated with recurrent anterior shoulder instability after arthroscopic Bankart repair (ABR). However, a threshold for the number of preoperative instability episodes that increases the risk of...
