Comparative Study
Relationship between quadriceps strength and patellofemoral joint chondral lesions after anterior cruciate ligament reconstruction.
The incidence of the patellofemoral joint chondral lesions after anterior cruciate ligament reconstruction (ACLR) is disturbingly high. Few studies have assessed the factors affecting patellofemoral joint chondral lesions postoperatively. ⋯ Greater than 80% recovery of quadriceps strength after ACLR is associated with less severe patellar cartilage damage at short-term follow-up.

Clinical studies of shoulder dislocations typically include adult patients (>16 years of age). Only small case series of patients aged 10 to 16 years are available to guide management. ⋯ Among 14- to 16-year-old patients, the rate of primary and recurrent shoulder CR mirrors that of high-risk adults (17-20 years of age) from previously published data; however, the rate of shoulder CR (primary or recurrent) is considerably lower among 10- to 13-year-olds. In addition to older patient age, male sex increased the odds of repeat shoulder CR. Going forward, clinicians should counsel male patients and those aged 14 to 16 years regarding their increased risk of recurrence after the nonoperative management of a primary anterior shoulder dislocation.

It is unknown if chronic hip pain due to femoroacetabular impingement (FAI) may cause sexual difficulties. Available evidence suggests that hip arthroscopic surgery may be effective for the treatment of symptomatic FAI; however, sexual function before and after hip arthroscopic surgery has not been reported. ⋯ This study demonstrates the prevalence of sexual difficulties among the majority of patients with symptomatic FAI, the significant effect that these difficulties may have on quality of life, and the ability of hip arthroscopic surgery to improve sexual function postoperatively. While further studies are required to elucidate what specific factors are associated with sexual difficulties, the current study suggests that this is an important topic to explore.

The common fresh-frozen allografts that are used for anterior cruciate ligament (ACL) reconstructions behave slower during the remodeling process and produce weaker tendon-bone integrations than do autografts. Decellularization of allogenic tendons results in a clean and porous collagen scaffold with low antigenicity and high compatibility, which may be more suitable for ACL reconstructions. ⋯ The pH-modified decellularized allograft may be a better graft option than the common fresh-frozen allograft for knee ligament reconstructions.

Review Meta Analysis
Early Versus Delayed Passive Range of Motion After Rotator Cuff Repair: A Systematic Review and Meta-analysis.
Postoperative rehabilitation has been shown to affect healing of the rotator cuff after surgical repair. However, it is unknown whether an early or delayed rehabilitation protocol is most beneficial for healing. ⋯ Evidence is lacking with regard to the optimal timing of PROM after RC repair; however, this study suggests that tear size may be influential.
