BackgroundNowadays, total hip arthroplasty (THA) is one of the most successful procedures in the field of orthopedics and trauma. The posterior approach has historically been associated with a higher rate of hip dislocation. To reduce the rate of hip dislocation in the posterior approach, most orthopedic surgeons would recommend hip precautions (HP) for their patients postoperatively based on previous theories. However, recent randomized controlled trials have shown no significant difference in hip dislocation rates with or without HP, in contrast to previous theories. Based on these, this study conducted a meta-analysis of these randomized controlled trials to try to get qualitative conclusions.MethodsRandomized controlled trials of HP after THA up to July 28, 2023, were searched in 3 databases, PubMed, Embase, and the Cochrane Library. Data extraction and literature quality assessment were performed by 2 independent authors and extracted hip dislocation, hip disability and Osteoarthritis Outcome Score, joint replacement (HOOS JR) scores over 6 weeks, and time to discontinuation of mobility aids. Stata software and Revman software were used to perform this meta-analysis.ResultsFollowing screening, 3 papers with a total of 1215 participants were included in the analysis. This meta-analysis showed that there was no statistically significant difference in hip dislocation rates with or without HP after THA undergoing the posterior approach and that the without HP group instead showed better outcomes in terms of HOOS JR scores and time to discontinuation of mobility aids.ConclusionTHA with a posterior approach does not require hip precautions.Copyright © 2024 the Author(s).
