The purpose in this investigation was to determine the biochemical composition of the normal rabbit medial collateral ligament (MCL) along its length during growth and maturation. Water content and hexosamine concentration as an index of glycosaminoglycan content and collagen concentration were quantified and results compared statistically for anatomically identified MCL segments at various age...

Reconstruction of the ulnar collateral ligament (UCL) remains the gold standard for treating overhead throwing athletes with valgus instability secondary to UCL pathology. Although surgical techniques for reconstruction have evolved over time, current methods allow 90% of patients to return to their preinjury level of activity. Despite encouraging results with reconstruction, UCL repair remains...

The purpose of this retrospective cohort comparison study was to determine the effect of ulnar collateral ligament reconstruction on postoperative range of motion (ROM) in patients undergoing posttraumatic elbow contracture release. Twenty-four consecutive patients underwent elbow arthrolysis. Six patients also underwent simultaneous collateral ligament excision and reconstruction, and 18 did n...

BACKGROUND Medial ulnar collateral ligament (MUCL) reconstruction is commonly performed on Major League Baseball (MLB) pitchers. Previous studies have reported that most pitchers return to presurgical statistical performance levels after MUCL reconstruction. METHODS Pitching performance data--specifically, earned run average (ERA), walks and hits per inning pitched (WHIP), winning percentage,...

The "Docking Plus" technique for elbow ulnar collateral ligament (UCL) surgery is described in the following text and video. Depite the general success of UCL surgery, significant rates of retear and failure of return to competition persist. Hypothesized reasons for UCL surgery failure include insufficient graft strength (midsubstance tears), insufficient graft tensioning (functional UCL insuff...

Background Ulnar collateral ligament reconstruction (UCLR) has become an increasingly common procedure among Major League Baseball (MLB) pitchers. The long-term effects of this procedure on the career of an MLB pitcher are largely unknown. Purpose/Hypothesis The purpose of this study was to determine why and when MLB pitchers who underwent UCLR during their careers retired from baseball as co...
