Mid-term Patient-reported Outcomes of Hip Arthroplasty After Previous Hip Arthroscopy: A Matched Case-control Study With a Minimum 5-year Follow-up
Authors: Rosinsky PJ, Chen JW, Shapira J, Maldonado DR, Lall AC, Domb BG
Background
This study examines whether a history of hip arthroscopy influences outcomes following total hip arthroplasty (THA), comparing patient-reported outcomes (PROs), complication rates, and revision surgery incidence between patients with and without prior hip arthroscopy.
Methods
Thirty-four patients with prior hip arthroscopy were matched to 89 controls without previous hip surgery. Both cohorts were followed for at least 5 years to assess PROs, complications, and revisions.
Key Findings
- PROs such as pain relief and satisfaction were similar between groups.
- Patients with prior arthroscopy exhibited significantly higher complication rates (2.6x) and revision surgery rates (13x) compared to controls.
Conclusions
Prior hip arthroscopy does not appear to impact patient satisfaction or pain outcomes after THA but is associated with increased risk for complications and revision surgery.
What Does This Mean for Providers?
Providers should counsel patients with prior hip arthroscopy about the elevated risks for postoperative complications and revision following THA, despite comparable functional outcomes. Enhanced perioperative planning and vigilant postoperative monitoring may be warranted in this population.
