Determining Clinically Meaningful Outcomes after Isolated Acetabuloplasty in the Context of Age and Arthritic Severity: A Retrospective Review of Prospectively Collected Data

摘要

Outcomes after isolated acetabuloplasty in mixed-type femoroacetabular impingement (FAI) patients can be favorable but are relatively unknown in the context of clinically important outcome variables (CIOVs) such as minimum clinically important difference and patient acceptable symptomatic state (PASS). Prognostic roles of age and osteoarthritis (OA) in hip arthroscopy are still unclear. We aimed to evaluate isolated acetabuloplasty outcomes including CIOVs while controlling for age and arthritis. This was a retrospective review of prospectively collected data. We analyzed patients with available 1-year follow-up for Patient-Reported Outcome Measurement Information System (PROMIS) scales for Physical Function (PF) and Pain Interference (PI). Patients were divided into two age groups (?0.615). When comparing patients reporting values above CIOV threshold versus those that did not, there were no differences in age (41.2?±?13.0 37.7, 44.8 vs. 45.9?±?13.2 38.4, 53.4, p?=?0.265) or Outerbridge grade distribution (p?=?0.177). This study uses CIOVs to describe clinically meaningful isolated acetabuloplasty outcomes for mixed-type FAI. Most patients over a wide spectrum of age and OA achieved favorable clinically meaningful outcomes following surgery. Isolated acetabuloplasty can alleviate symptomatology in mixed-type FAI patients on a case-by-case basis.
