Anterior cruciate ligament injuries are common in professional football players, and their career impact is unclear. ⋯ Nearly four fifths of National Football League running backs and wide receivers who sustain an anterior cruciate ligament injury return to play in a game. On return to competition, player performance of injured players is reduced by one third.

Randomized Controlled Trial
Ultrasound-guided sclerosis of neovessels in painful chronic patellar tendinopathy: a randomized controlled trial.
Color Doppler ultrasound examination frequently reveals neovascularization in chronic painful Achilles and patellar tendinopathy. Sclerosing the area with vascular ingrowth using polidocanol has shown promising clinical results in patients with Achilles tendinopathy. ⋯ Sclerosing injections with polidocanol resulted in a significant improvement in knee function and reduced pain in patients with patellar tendinopathy.

Multicenter Study Clinical Trial
Patellofemoral full-thickness chondral defects treated with Hyalograft-C: a clinical, arthroscopic, and histologic review.
Tissue engineering has emerged as a potential therapeutic option for cartilage regeneration. ⋯ Biodegradable scaffolds seeded with autologous chondrocytes can be a viable treatment for chondral lesions. The type of tissue repair achieved demonstrated histologic characteristics similar to normal articular cartilage. Long-term investigations are needed to determine the durability of the repair produced with this technique.

During the past decade, developments in arthroscopic technology have made arthroscopic repair of labral lesions feasible. However, results with the use of the transglenoid suture technique, or with the use of bioabsorbable tacks, have remained variable in the literature, and the recurrence rates are still inferior to those of open Bankart repair. ⋯ Glenohumeral translation and rotation after arthroscopic Bankart repair with use of suture anchors approached near normal values, confirming the clinical success of this technique.

Overhead-throwing athletes have increased external and diminished internal glenohumeral rotation that may alter glenohumeral kinematics. ⋯ Significant changes in glenohumeral motion occur in this model during the simulated late-cocking and follow-through phases of throwing. In this model, posterior capsular tightness alters the humeral head position most profoundly during the deceleration and follow-through phases of throwing.
