Acromioclavicular (AC) joint injuries, particularly sprains, are common in athletic populations and may result in significant time lost to injury. However, surprisingly, little is known of the epidemiology of this injury. ⋯ Acromioclavicular separations are relatively common in young athletes. Most injuries occur during contact sports such as rugby, wrestling, and hockey. Male athletes are at greater risk than female athletes. Intercollegiate athletes are at greater risk than intramural athletes. The average time lost to sport due to AC joint injury was 18 days, with low-grade injuries averaging 10 days lost. High-grade injuries averaged 64 days lost to sport, and 71% elected to undergo surgical repair/reconstruction.

Randomized Controlled Trial Comparative Study
Comparison of early versus delayed weightbearing outcomes after microfracture for small to midsized osteochondral lesions of the talus.
The initiation of weightbearing is the focus of postoperative treatment after microfracture for osteochondral lesions of the talus. However, no comparative clinical study has been performed on early and delayed weightbearing after microfracture for osteochondral lesions of the talus. ⋯ Two postoperative treatments differing by weightbearing status after arthroscopic microfracture for small to midsized osteochondral lesions of the talus showed good clinical results and similar outcomes in terms of the AOFAS score, VAS score, and AAS. The study shows that early weightbearing postoperative regimens can be recommended for patients treated by microfracture for small to midsized osteochondral lesions of the talus.

There is increasing evidence that a significant proportion of randomized trials in medicine, and recently in orthopaedics, do not go on to publication. ⋯ Although registration of sports medicine trials in CTG does not consistently result in publication or disclosure of results at 32 months from the time of study completion, observed publication rates are higher than in other orthopaedic subspecialties. Changes are also frequently made to the final presentation of eligibility criteria and primary and secondary outcomes that are not reflected in the registered trial data.

Despite improvements in arthroscopic rotator cuff repair technique and technology, a significant rate of failed tendon healing persists. Improving the biology of rotator cuff repairs may be an important focus to decrease this failure rate. The objective of this study was to determine the mRNA biomarkers and histological characteristics of repaired rotator cuffs that healed or developed persistent defects as determined by postoperative ultrasound. ⋯ The upregulation of tissue remodeling genes in the torn rotator cuff at the time of surgery provides a snapshot of the biological environment surrounding the torn rotator cuff that is closely related to the healing of repaired rotator cuffs.

Injuries to the shoulder are common in collegiate football, and injuries to the acromioclavicular (AC) joint have previously accounted for up to 41% of all shoulder injuries. ⋯ AC joint injuries in NCAA football players are predominantly low-grade sprains, leading to approximately 12 days of lost competition. The few severe sprains that occurred often resulted in surgery or required approximately 5 weeks of rehabilitation.
