Combined hip arthroscopy with periacetabular osteotomy for hip dysplasia: a systematic review.

Periacetabular osteotomy (PAO) is a surgical procedure that corrects acetabular dysplasia without necessarily addressing intra-articular pathology. Hip arthroscopy is being increasingly used to address soft tissue pathologies at the time of a PAO. This review aims to determine patient-reported outcome measure scores (PROMs) of combining hip arthroscopy and PAO.

Do 3-dimensional Spinopelvic Characteristics Normalize After THA? A Prospective, Comparative Study Using Motion Capture Analysis.

Background: Spinopelvic stiffness (primarily in the sagittal plane) has been identified as a factor associated with inferior patient-reported outcomes (PROs) and increased dislocation risk after THA. Incorporating preoperative spinopelvic characteristics into surgical planning has been suggested to determine a patient-specific cup orientation that minimizes dislocation risk. Sagittal plane radiographic analysis of static postures indicates that patients exhibit a degree of normalization in their spinopelvic characteristics after THA.

Mid to long-term survivorship of hip arthroplasty in patients 40 years and younger.

Background: Etiology of hip osteoarthritis (OA) and survival of hip arthroplasty in the young (below 40-years-old) remains poorly described. Furthermore, joint survivorship mid to long-term and PROMs according to the etiology are unclear. The study aims were to 1) identify the indications for arthroplasty in the below 40-years-old cohort; 2) define hip arthroplasty outcomes in the young and 3) test whether patients with sequelae of pediatrics hip disease have inferior outcome compared to other patients.

Development and implementation of a roadmap for improving quality of care in prearthritic hip disease: A journey over 20 years.

The understanding and treatment of prearthritic hip disease has evolved remarkably over the past 20 years. The principal investigator and the multicenter Academic Network of Conservational Hip Outcomes Research (ANCHOR) group have had a key role in improving the quality of care for these patients suffering from the three most common prearthritic conditions: femoroacetabular impingement, developmental dysplasia of the hip, and residual Legg-Calve-Perthes Disease. We aim to demonstrate that based on the six quality of care dimensions as defined by Donabedian, our 20-year academic journey has markedly improved the quality of care for young patients with prearthritic hip disease.

How to Best Identify Acetabular Retroversion on Radiographs: Thresholds to Guide Clinical Practice.

Background: Acetabular retroversion is associated with impingement and instability. An adequate interpretation of acetabular version and coverage on radiographs is essential to determine the optimal treatment strategy (periacetabular osteotomy vs hip arthroscopic surgery). The crossover sign (COS) has been associated with the presence of acetabular retroversion, and the anterior wall index (AWI) and posterior wall index (PWI) assess anteroposterior acetabular coverage.
