Previous studies investigating acromioclavicular (AC) joint injuries in professional American football players have only been reported on quarterbacks during the 1980s and 1990s. These injuries have not been evaluated across all position players in the National Football League (NFL). ⋯ Shoulder injuries, particularly those of the AC joint, occur frequently in the NFL. These injuries can result in time lost but rarely require operative management. Quarterbacks had the highest incidence of injury; however, this incidence is lower than in previous investigations that evaluated these injuries during the 1980s and 1990s.

Multiple concussions have been associated with prolonged symptoms, recovery time, and risk for future concussions. However, very few studies have examined the effect of multiple concussions on neurocognitive performance and the recently revised symptom clusters using a large database. ⋯ Concussed athletes with a history of ≥3 concussions take longer to recover than athletes with 1 or no previous concussion. Future research should concentrate on validating the new symptom clusters on multiple concussed athletes, examining longer recovery times (ie, >8 days) among athletes with multiple concussions.

Meniscus injuries are common in patients with anterior cruciate ligament (ACL) tears. Patient demographics, surgeon characteristics, and concurrent diagnostic factors affecting the prevalence of meniscus repairs in patients undergoing ACL reconstruction (ACLR) by community-based orthopaedic surgeons have not been fully studied. ⋯ Younger patient age, lower patient BMI, surgeon's sports medicine fellowship training, higher surgeon case volume, and higher site volume are associated with a higher likelihood of a meniscus repair in patients undergoing primary ACLR in a large cohort from a community-based ACLR registry.

The rate of healing failure after surgical repair of chronic rotator cuff tears is considerably high. ⋯ The use of PRP might be a biological supplement to increase the rotator cuff healing rate, which still remains low even after successful cuff repair, but this result should be interpreted with caution regarding clinical applications.
