Early clinical results of anterolateral ligament (ALL) reconstruction are promising, but concerns exist due to high rates of complications after other types of lateral extra-articular tenodesis. The rate of surgery after combined anterior cruciate ligament (ACL) and ALL reconstruction is not known. ⋯ The reoperation rate after combined ACL and ALL reconstruction in this series is broadly comparable to the reoperation rate after isolated ACL reconstruction as reported in previous studies. In addition, the high rates of knee stiffness and reoperation reported in historical series of nonanatomic, lateral extra-articular tenodesis were not observed in the current series.

Comparative Study
Early Functional Outcomes of Periacetabular Osteotomy After Failed Hip Arthroscopic Surgery for Symptomatic Acetabular Dysplasia.
Persistent acetabular dysplasia is a common reason for the failure of hip arthroscopic surgery; however, the effect of prior hip arthroscopic surgery on functional outcomes after subsequent periacetabular osteotomy (PAO) is unknown. Hypothesis/Purpose: The purpose of this study was to (1) compare demographic and radiological findings in patients who had and had not undergone previous hip arthroscopic surgery before PAO for symptomatic acetabular dysplasia and (2) compare the short-term, hip-specific patient-reported outcomes in these same patient populations. It was hypothesized that prior hip arthroscopic surgery is associated with worse early functional outcomes in PAO. ⋯ Failed hip arthroscopic surgery before PAO for symptomatic hip dysplasia is associated with lower hip-specific functional outcomes within the first 1 year of follow-up despite similar baseline demographic and radiological characteristics. These differences persisted in certain outcome scores (mHHS, HOS-Sport) at last follow-up but were less pronounced than at 1 year.

Comparative Study
Comparison of Concussion Rates Between NCAA Division I and Division III Men's and Women's Ice Hockey Players.
Examinations related to divisional differences in the incidence of sports-related concussions (SRC) in collegiate ice hockey are limited. ⋯ Concussion rates did not vary by sex but differed by division among men. Checking-related concussions were less common in women than men overall but more common in Division I women than Division III women. Findings highlight the need to better understand the reasons underlying divisional differences within men's and women's ice hockey and the need to develop concussion prevention strategies specific to each athlete population.

Studies on midterm outcomes of the arthroscopic treatment of femoroacetabular impingement (FAI) and labral tears with mild osteoarthritis (OA) are limited. ⋯ The arthroscopic treatment of FAI and labral tears in patients with Tönnis grade 1 had good results at 5-year follow-up. After controlling for other variables using a matched-pair comparison, patients with Tönnis grade 1 had similar, durable improvements to those with Tönnis grade 0. While strict surgical indications and appropriate expectations are recommended for patients with mild OA, Tönnis grade 1 alone should not be considered a contraindication to hip arthroscopic surgery.

The Segond fracture was classically described as an avulsion fracture of the anterolateral capsule of the knee. Recently, some authors have attributed its pathogenesis to the "anterolateral ligament" (ALL). Biomechanical studies that have attempted to reproduce this fracture in vitro have reported conflicting findings. ⋯ The results of this study confirmed that while the Segond fracture occurs at the location of the tibial insertion of the ALL, as reported in the literature, MRI was unable to identify any distinct ligamentous attachment. MRI analysis revealed that soft tissue attachments to the Segond fracture were the posterior fibers of the ITB and the lateral capsule in 94% of patients.
