Lateral meniscal injury is a common and possibly career-threatening injury among players in the National Football League (NFL). The rate of return to play (RTP) and factors that affect RTP after lateral meniscal injury in NFL players are currently not defined. ⋯ The majority of NFL players undergoing arthroscopic lateral meniscectomy are able to return to play. Players selected earlier in the NFL draft and who are listed as starters in more of their games are more likely to return to play, as are linemen and tight ends. It is significantly more difficult for running backs, receivers, linebackers, and defensive backs to return to play.

There are limited data reporting outcomes after revision arthroscopic surgery for residual femoroacetabular impingement (FAI). ⋯ Arthroscopic hip revision surgery for residual FAI yielded significantly improved outcome measures, but these were inferior to those after primary arthroscopic FAI corrective surgery. Improved femoral head-neck offset after cam decompression, identification and treatment of subspine/AIIS impingement, labral preservation/reconstruction, and capsular preservation/plication may be paramount to achieve satisfactory outcomes.

Previous studies have found differences in meniscus and cartilage injury rates between groups of patients after primary and revision anterior cruciate ligament reconstructions (ACLRs). This study examined a cohort of individual patients who underwent primary and subsequent revision ACLR to determine the incidence of cartilage and meniscus disease. ⋯ In this community-based sample followed from primary ACLR to revision ACLR, the prevalence of articular cartilage injuries increased, while the prevalence of meniscus injuries decreased. The higher prevalence of articular cartilage injuries at revision ACLR may represent new injuries. The lower prevalence of meniscus tears at revision ACLR may be caused by susceptible menisci being injured and treated at primary surgery or by changes in knee kinematics or injury exposure patterns.

Anterior cruciate ligament (ACL) injuries are disabling and are associated with the early onset of posttraumatic osteoarthritis. Little is known regarding the incidence rate of first-time noncontact ACL injuries sustained during athletic events and how they are independently influenced by level of competition, type of sport, and the participant's sex. ⋯ An athlete's risk of having a first-time noncontact ACL injury is independently influenced by level of competition, the participant's sex, and type of sport, and there are no interactions between their effects. Female college athletes have the highest risk of having a first-time noncontact ACL injury among the groups studied.

Matrix-induced autologous chondrocyte implantation (MACI) is an established technique for the repair of knee chondral defects, although the correlation between clinical and radiological outcomes after surgery is poorly understood. ⋯ Apart from some consistent evidence of an association between the KOOS and effusion, this analysis demonstrated a limited correlative capacity between clinical and radiological outcomes up to 5 years after surgery.
