Posterior tibial slope (PTS) has recently been identified as a risk factor for anterior cruciate ligament (ACL) injuries because of an associated increase in anterior tibial translation (ATT) and ACL loading. However, few studies concerning the correlation between PTS and postoperative ATT have been published. ⋯ There was a significant correlation between PTS and postoperative anterior knee static stability in this study. Patients with a steeper medial or lateral PTS showed a higher risk of ATT ≥5 mm at thresholds of 5.6° and 3.8°, respectively.

In spite of the high prevalence of shoulder stiffness during rotator cuff repair, optimal management remains unclear. ⋯ Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes. The outcomes did not differ between treatment methods for stiffness regardless of the severity of stiffness. In patients with diabetes mellitus however, capsular release at the time of rotator cuff repair seems to be beneficial, especially for external rotation and final postoperative function.

Rotator cuff tears are a common cause of pain and disability of the shoulder. Information on the prevalence and identification of potential risk factors could help in early detection of rotator cuff tears and improve treatment outcome. ⋯ Patients treated for partial and full-thickness rotator cuff tears have a significantly higher risk of having a tear on the contralateral side and have noticeable deficits in their shoulder function regarding activities of daily living even if the tear is otherwise asymptomatic.

Ulnar collateral ligament (UCL) reconstructions are relatively common among professional pitchers in Major League Baseball (MLB). To the authors' knowledge, there has not been a study specifically analyzing pitching velocity after UCL surgery. These measurements were examined in a cohort of MLB pitchers before and after UCL reconstruction. ⋯ There were no significant differences in pitch velocity and common performance measurements between players who returned to MLB after UCL reconstruction and pair-matched controls.

Because chondrocyte viability is imperative for successful osteochondral allograft transplantation, sterilization techniques must provide antimicrobial effects with minimal cartilage toxicity. Chlorhexidine gluconate (CHG) is an effective disinfectant; however, its use with human articular cartilage requires further investigation. ⋯ This study offers a scientific protocol for sterilizing osteochondral fragments that does not adversely affect cartilage viability.
