Graft extrusion after meniscus allograft transplantation (MAT) may be affected by horn fixation, which differs between medial and lateral MAT. Few studies have compared graft extrusion, especially sagittal extrusion, after medial and lateral MAT. ⋯ The amount and incidence of graft extrusion were greater after medial than lateral MAT in both the coronal and sagittal planes. In the sagittal plane, graft extrusion was greater and more frequent on the anterior than the posterior horn in both medial and lateral MAT. However, graft extrusion was not correlated with early clinical outcomes after both medial and lateral MAT.

Recent studies have questioned the efficacy of meniscectomy in older patients with and without evidence of osteoarthritis; however, it continues to be frequently performed. There is limited information about age and other risk factors for adverse events and readmission after the procedure. This knowledge is vital to understand the true risk profile of this common surgery. ⋯ Knowledge of these risk factors for adverse events and readmission provides essential information for patient selection and preoperative counseling.

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.
