Concussion injuries are common in professional football players; however, their effect on player performance remains unclear. ⋯ A high rate of National Football League running backs and wide receivers are able to return to play after a concussion injury. These players were found to perform at a similar level in both the acute and long-term period after concussion.

Studies on the effect of partial- and full-thickness chondral damage of the hip on outcomes and the ability to achieve meaningful clinical outcomes are limited. ⋯ Patients with grade IV chondral defects experienced worse functional outcomes, lower satisfaction, and increased pain when compared with both patients without chondral damage or grade I-III chondromalacia at 2-year follow-up. Several predictors were associated with achieving clinically significant function in patients undergoing hip arthroscopic surgery for FAIS.

Intra-articular injection of adipose-derived stem cells (ASCs) has shown promise for improving symptoms and cartilage quality in the treatment of osteoarthritis (OA). However, while most preclinical studies have been performed with plastic-adherent ASCs, most clinical trials are being conducted with the stromal vascular fraction (SVF), prepared from adipose tissue without prior culture. ⋯ It was observed that both ASCs and SVF resulted in clinical improvement in patients with knee OA, but that ASCs outperform SVF in the early reduction of symptoms and pain with less comorbidity.

Ulnar collateral ligament (UCL) reconstruction is commonly performed among overhead throwing athletes. Previous studies demonstrated relatively high rates of return to sport after primary reconstruction. Outcomes after revision UCL reconstruction have not been widely studied. ⋯ This systematic review demonstrated a limited rate of return to preinjury level of sport among elite-level baseball players who underwent revision UCL reconstruction. Pitching durability and career longevity were inferior to results that were reported for players who underwent primary UCL reconstruction alone. This study suggests that outcomes after revision UCL reconstruction are not reliable and elite-level players should be counseled accordingly.
