The relationship between muscle injury and strength disorders remains a matter of controversy. ⋯ The outcomes showed that isokinetic intervention gives rise to the preseason detection of strength imbalances, a factor that increases the risk of hamstring injury. Restoring a normal strength profile decreases the muscle injury incidence.

Type II superior labral anterior-posterior lesions in throwers are often associated with anterior shoulder capsular laxity. ⋯ Anterior shoulder capsular laxity associated with type II superior labral anterior-posterior lesions may cause anterior shoulder instability at 90 degrees of shoulder abduction in throwers even after superior labral anterior-posterior lesion repair.

Chondrolysis initiated by postoperative, intra-articular pain pumps has recently been described by multiple institutions. ⋯ The results of this study may help improve the safety of intra-articular pain pump use by examining the effects of local anesthetics on chondrocyte viability.

Clinical Trial
In vivo comparison of changes in glenohumeral translation after arthroscopic capsulolabral reconstructions.
The objective of this study was to quantify anteroposterior glenohumeral translation of patients undergoing arthroscopic capsulolabral repairs using cutaneous electromagnetic position sensors. ⋯ Arthroscopic superior capsulolabral reconstructions successfully restored anteroposterior translation. However, arthroscopic capsulolabral techniques for treating recurrent anterior or posterior instability resulted in decreased anteroposterior translation compared to the uninvolved side while restoring external rotation.

Controlled Clinical Trial
Biomechanical and radiographic analysis of partial coracoclavicular ligament injuries.
A spectrum of acromioclavicular joint injuries may exist between type II acromioclavicular joint disruption (coracoclavicular strain) and type III acromioclavicular joint injuries (coracoclavicular disruption). This may help explain the variability in outcomes seen in patients with type II acromioclavicular injuries. ⋯ Zanca radiograph may detect incomplete injury to the coracoclavicular ligaments associated with acromioclavicular disruption.
