In 2010, the National Collegiate Athletic Association (NCAA) adopted its Concussion Policy and Legislation, which applies to more than 450,000 collegiate athletes annually. To date, there has been no examination of school-level compliance with the NCAA Concussion Policy. ⋯ Although a large majority of respondents indicated that their school has a concussion management plan, improvement is needed. Compliance with specified components (eg, annual athlete education) lags behind the presence of the plan itself, and stakeholders had suggestions for areas in which improvements are needed. Increasing scientific evidence supporting the seriousness of concussion underscores the need for the NCAA to use its regulatory capabilities to ensure that athletes' brains are safe.

Arthroscopic acetabuloplasty was initially described with detachment of the labrum to access the acetabular rim for resection, followed by labral refixation. Recent technical improvements have made it possible to perform acetabuloplasty and labral refixation without labral detachment when the chondrolabral junction is intact. ⋯ Treatment of pincer- and combined-type impingement with arthroscopic acetabuloplasty and labral refixation without detachment, when possible, resulted in similar patient outcomes compared with acetabuloplasty with labral detachment. We may conclude that in cases where the chondrolabral junction remains intact, acetabuloplasty and labral refixation without detachment is a viable option.

Comparative Study
Biomechanical comparison of patellar fixation techniques in medial patellofemoral ligament reconstruction.
Multiple techniques for reconstruction of the medial patellofemoral ligament (MPFL) have been described; however, little is known about the biomechanical properties of these techniques. Fixation of the graft to the patella has not been studied in a human cadaveric model. ⋯ This study compares the biomechanical properties of 2 commonly used methods for patellar graft fixation in MPFL reconstruction surgery. It supports the use of interference screw fixation based on the ultimate load and stiffness, although suture anchor fixation may be sufficient when compared with the native MPFL based on previously published data.

There has been an increase in minimally invasive surgery for chronic exertional compartment syndrome (CECS), despite the potential for incomplete compartment release and iatrogenic injuries. To our knowledge, no study has examined the effect of the length of fascial release on compartment pressures. ⋯ The results suggest that even in cases with near complete fascial release, intracompartmental pressures may decrease enough to provide symptomatic relief and avoid possible iatrogenic injuries associated with percutaneous release. It is unknown whether the swine model may adequately translate to the clinical setting; thus, recommendations should be taken with caution, and future studies should be performed to examine the correlation in a human model.

In biceps tenodesis for intra-articular tears, determining the distal extension of the lesions through the biceps groove is important in choosing the optimal tenodesis site. ⋯ In approximately 80% of the intra-articular biceps tears evaluated in this study, a "hidden lesion" was observed going beyond the bicipital groove and extending to the distal extra-articular portion. Therefore, the subpectoral portion may be considered the optimal tenodesis site for the complete removal of all hidden biceps lesions.
