Hip arthroscopy failure rates: a healthcare database analysis in the United States.

With hip arthroscopy cases, there has been a concomitant increase in complications and the need for revision surgery. This study aims to further contribute to the literature regarding hip arthroscopy failure rates and associated patient factors following an index hip arthroscopy procedure. The PearlDiver database was queried for patients who had undergone hip arthroscopy. International Classification of Diseases, 10th Revision, Clinical Modification codes were used to ensure that follow-up was performed on the ipsilateral limb. Hip arthroscopy failure was defined specifically as subsequent ipsilateral total hip arthroplasty (THA) and reoperation, which were examined in all patients that met inclusion criteria. Independent patient variables, including psychiatric comorbidities, preoperative SSRI use, smoking, and obesity, were examined to identify an association with failure rates. A Student -test, with a significance set at  < 0.05, was used for statistical comparisons of postoperative outcomes. Odds ratios were used to calculate the probability of short-term hip reoperation in patients with the above independent variables. A total of 19 067 hip arthroscopy patients were included in this study. Within 2 years from the index hip arthroscopy, there was an 11.42% failure rate as defined by subsequent reoperation and 7.16% failure rate as defined by revision to THA, with a total revision surgery rate of 18.58%. The most common reoperation procedure was revision femoroplasty (72%). Patients with an active diagnosis of a psychiatric comorbidity in the year leading up to a hip arthroscopy procedure were 1.74 times more likely to require a hip reoperation within 1 year (95% CI, 1.55-1.95).
