Complications can be defined as preventable, potentially preventable, or non-preventable. While often discussed, there are virtually no data whether or not the most common causes of revision total hip arthroplasty (THA) are preventable or not. The goal of this study was to identify and report preventable causes of revision THA within 5 years of the index THA. We conducted a retrospective review of 128 consecutive revision THAs between August 2015 and August 2017, with 62% being referred from another institution. Mean time to revision THA from the index arthroplasty was 10 months. Mean age at revision THA was 61 years, with 67% being female. Three fellowship-trained adult reconstruction surgeons reviewed the radiographs and operative notes and classified the revision THAs into two categories: preventable vs. non-preventable. Reviewers were instructed to be extremely lenient with the benefit of the doubt given to the operative surgeon. Inter-observer reliability was assessed by Cohen's kappa analysis.Introduction
