Patient-Reported Outcomes Following Periacetabular Osteotomy versus Hip Arthroscopy for Borderline Acetabular Dysplasia Are Comparable: A Systematic Review.

Purpose: The purpose of this systematic review was to compare patient populations and outcomes in studies treating borderline hip dysplasia (BHD) with either hip arthroscopy or periacetabular osteotomy (PAO). We hypothesized that studies would show significant postoperative improvement following both PAO and arthroscopy for BHD, and that subjects undergoing arthroscopy would have a higher rate of Cam morphology.

Methods: A literature review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted to identify studies published after 2014 that reported patient-reported outcome measures (PROMs) following hip arthroscopy or PAO for BHD.

Radiographs Underestimate Lateral Center-Edge Angle and Tönnis Angle Measurements Compared to Computed Tomography Scan in Assessment of Borderline and Frank Acetabular Dysplasia.

Purpose: To compare lateral center-edge angle (LCEA) and Tönnis angle (TA) values measured in radiographs and computed tomography (CT) scans with commercially available software and to determine the degree of concurrence in the classification of acetabular dysplasia as depicted in radiographs and CT scans.

Methods: Retrospectively collected data from patients undergoing preoperative CT protocol and x-rays for hip arthroscopy from June 2019 to December 2021. The preoperative anteroposterior supine view of the pelvis was utilized to measure LCEA and TA, and measurements were compared to CT scan views through commercially available software.

Predicting Outstanding Results Following Primary Total Hip Arthroplasty Using the Maximal Outcome Improvement Threshold.

Background: The delta difference between baseline patient-reported outcome measure scores and postoperative scores is used to measure success following primary total hip arthroplasty (THA). However, statistical improvement is not necessarily equal to clinical benefit. The percentage of the maximal outcome improvement (MOI) is a psychometric tool to determine clinical improvement.

Editorial Commentary: Primary Treatment of Hip Labral, Osseous, Chondral, Capsular, and Extra-Articular Pathology Is Essential: Outcomes Following Revision Are Less Predictable.

Appropriate labral management is one of many procedures during hip arthroscopy that affects postoperative outcomes and revision rates. Both primary labral repair and reconstruction have been shown to have superior clinical and functional outcomes compared with labral debridement when treating unstable labral tears. Arthroscopic labral reconstruction is one of the most powerful techniques in the arsenal of complex hip-preservation surgeons, and although often reserved for the revision setting, when the native labrum is irreparable, a primary reconstruction may be indicated when the only alternatives are selective labral debridement or a suboptimal repair.

Study Design: Systematic Review, Level of Evidence 1.

Editorial Commentary: Concomitant Hip Arthroscopy and Periacetabular Osteotomy Treat Both the Cause and the Effects of Hip Dysplasia: The Best of Both Worlds.

In the management of true hip dysplasia, the bony deformity is nearly always accompanied by, and often causal of, intra-articular pathology. It is strongly recommended to conduct a comprehensive preoperative evaluation as well as arthroscopic evaluation and treatment of coexisting hip joint conditions prior to performing an open Bernese periacetabular osteotomy. The osteotomy improves coverage of the femoral head and corrects the abnormal joint mechanics and loading patterns, which result in cartilage damage and subsequent osteoarthritis.

A comprehensive review of hip arthroscopy techniques and outcomes.

Transforming the orthopedic landscape, hip arthroscopy pioneers a minimally invasive surgical approach for diagnosing and addressing hip pathologies. With its origins dating back to Burman's 1931 cadaveric study, this groundbreaking technique gained clinical relevance in 1939 through Takagi's report. However, the 1980s marked the actual emergence of hip arthroscopy for treating a wide range of hip disorders.
