Effect of Previous Hip Arthroscopy on Results after Hip Arthroplasty: Systematic Review and Meta-Analysis

Abstract Background Hip arthroplasty is the most frequently performed adult reconstructive hip procedure. Total hip arthroplasty (THA) is one of the most successful procedures performed in modern orthopedics. The primary indication for THA in a patient with endstage arthropathy is pain resulting in significant limitation of physical activity. Important factors to be considered in the decision to recommend or undergo THA are patient age, diagnosis, and medical comorbidities. Aim of the Work This review pursues to systematically review the current evidence in the literature to determine whether previous hip arthroscopy would direct to inferior results in patients undergoing succeeding hip arthroplasty. Patients and Methods The first literature search identified 412 studies in total. After removing duplicates, 307 articles were deemed irrelevant based on their title and Abstractscreening. Eighty- two papers were eliminated from the remaining 105 research based on their title and Abstract. After carefully reviewing the entire text of all remaining publications, 11 studies were eliminated for reasons such as conference Abstracts, reviews, and lack of comparison between intervention and control groups. Additionally, one cohort research that compared THA results in patients who had previously undergone hip salvage surgery to those who had not previously undergone hip salvage surgery was removed. Finally, eleven studies spanning the years 2012 to 2019 were available for meta-analysis. Results Of these citations could result from the studies’ varying designs and sample sizes. Estimated blood loss, on the other hand, was deemed a reasonable indicator of operating time. The consistency in blood loss between the groups may reflect a similar operative time. Conclusion Patients who have previously undergone hip arthroscopy are more likely to experience postoperative complications such as dislocation, revision, and reoperation following subsequent hip arthroplasty. On the other hand, prior hip arthroscopy did not appear to affect functional or intraoperative results.
