Anterior cruciate ligament (ACL) injury is one of the most frequent orthopaedic injuries and reasons for time loss in sports and carries significant implications, including posttraumatic osteoarthritis (OA). Instability associated with ACL injury has been linked to the development of secondary meniscal tears (defined as tears that develop after the initial ACL injury). To date, no study has examined secondary meniscal tears after ACL injury and their effect on OA and arthroplasty risk. ⋯ Secondary meniscal tears after ACL injury are most common among patients undergoing delayed surgical or nonoperative treatment of their primary ACL injuries. Secondary tears often present as complex tears of the medial meniscus and result in high rates of partial meniscectomy.

There is a paucity of information regarding the treatment of posterior labral tears of the shoulder for baseball players. Reports regarding treatment and postoperative outcomes are more limited than its anterior and superior counterparts. ⋯ Arthroscopic treatment of posterior labral tears of baseball players was effective in improving pain and function, resulting in 94% patient satisfaction and 94% return to sport, with 61% returning to previous level of play. Patient presentation is variable, with a majority of patients citing pain rather than instability.

The rate of secondary knee injuries after pediatric anterior cruciate ligament (ACL) injury is uncertain, and previous studies are limited because of poor methodology. ⋯ The incidence of new meniscal tears after pediatric ACL injury was 34% during a mean follow-up period of 9.5 years. At final follow-up, 27 patients (57%) had normal menisci, and none had developed knee osteoarthritis. Primary active rehabilitation, close follow-up, and delayed surgery if needed may be a viable and safe treatment option for some pediatric ACL injuries.

Anterior cruciate ligament (ACL) reconstruction in adolescents is commonly performed with hamstring tendon autografts. Small graft diameter is one risk factor for graft failure and options to upsize the autologous hamstring graft include allograft augmentation and tripling one or both of the hamstring tendons. ⋯ ACL reconstruction with hamstring tendon autografts augmented with allografts has a significantly increased risk of graft rupture compared with comparably sized hamstring tendon autografts. In situations where the surgeon harvests an inadequately sized 4-strand autograft, we recommend obtaining a larger graft diameter by tripling the semitendinosus rather than augmenting with an allograft.

Hip arthroscopy for femoroacetabular impingement syndrome (FAIS) is a rapidly growing field in sports surgery; however, factors associated with poor outcomes and identification of predictor models of inferior clinical outcomes is unclear. ⋯ This study demonstrates that 73% of all patients treated for symptomatic FAIS with primary hip arthroscopy and routine capsular closure achieved the MCID. Clinical failure is predicted by a number of modifiable and nonmodifiable factors, including chronic preoperative pain and presence of chondromalacia. The current study updates the midterm failure rates and outcomes achievable with hip arthroscopy for FAIS.
