Return-to-Play Outcomes in Professional Baseball Players After Medial Ulnar Collateral Ligament Injuries: Comparison of Operative Versus Nonoperative Treatment Based on Magnetic Resonance Imaging Findings.

Background: The medial ulnar collateral ligament (UCL) is the primary static stabilizer to valgus stress of the elbow. Injuries to the UCL are common in baseball pitchers. In the 1970s, reconstructive surgery was developed.

Clinical outcomes following osteochondral autologous transplantation (OATS).

This study evaluated the clinical outcome in 21 patients (22 knees) undergoing osteochondral autologous transplantation (OATS) in the knee over a 5-year period. Sixteen knees in 15 patients were available for follow-up at an average of 40 months after the procedure. The clinical outcome was analyzed using the IKDC and Knee and Osteoarthritis Outcome Score (KOOS) evaluation forms, a subjective questionnaire, and a clinical examination.

Associations of body mass index with meniscal tears.

Background: Meniscal tears are common knee injuries, with limited reported data on associated factors, let alone risk factors. The objective of this study was to determine whether associations exist between increasing obesity and meniscal tears leading to surgery.

Methods: We performed frequency-matched case-control studies using surgical case data for years 1996 to 2000 from administrative databases of two large Utah hospitals; each case was matched with three controls from a large cancer screening trial.
