Overview

Cohort study reveals higher total hip arthroplasty conversion after hip arthroscopy in acetabular retroversion, indicating retroversion predicts long-term surgical failure.

Key Points

  • To determine whether global acetabular retroversion reduces long-term total hip arthroplasty-free survivorship following primary hip arthroscopy for femoroacetabular impingement.
  • Retrospective 1:1 propensity score–matched cohort study of 98 patients (49 with global acetabular retroversion and 49 controls) aged ≥18 years undergoing primary hip arthroscopy between 2001 and 2013.
  • Patients were matched by age, sex, body mass index, and labral treatment (repair vs debridement) with a minimum follow-up of 8 years (mean 10.7 vs 11.1 years).
  • Total hip arthroplasty-free survivorship was significantly lower in patients with global acetabular retroversion compared to matched controls (68.6% vs 83.9%, P = .036).
  • Multivariate Cox regression demonstrated a significantly increased risk of conversion to total hip arthroplasty in the retroversion group (hazard ratio, 3.94; P = .039).
  • Patients with retroversion exhibited higher rates of severe chondrolabral junction breakdown (P = .010), though patient-reported outcome measures did not differ significantly between groups at final follow-up.
