The prevalence of hip labral and chondral lesions identified by method of detection during periacetabular osteotomy: arthroscopy versus arthrotomy.
Abstract: Periacetabular osteotomy (PAO) has become an accepted treatment option for patients with severe hip dysplasia. In addition to correcting acetabular architecture, consideration has been given to concomitant joint evaluation and treatment of coexisting intra-articular pathologic conditions, which can be identified with hip arthroscopy or through an open arthrotomy. The purpose of this systematic review was to evaluate the prevalence of intra-articular pathologic conditions identified arthroscopically compared with that of those identified with open arthrotomy.
METHODS: A systematic review of the literature was performed by a search of PubMed using the words "periacetabular osteotomy," "Bernese osteotomy," and "Ganz osteotomy." Two reviewers searched for relevant articles that met established inclusion criteria, which follow: (1) they were in the English language, (2) they contained data on patients who underwent periacetabular osteotomy, (3) the study patients underwent concomitant arthroscopy or arthrotomy, and (4) the studies contained data on the intra-articular findings at the time of osteotomy. Exclusion criteria included review articles, technique articles, articles reporting on the same patient population, and articles without reported patient data.
