Background:
Hip resurfacing (BHR) is an alternative to total hip arthroplasty (THA), especially suited for younger patients seeking hip replacement. This study compares hip resurfacing outcomes with those of THA performed via direct anterior or posterior approaches over a minimum 5-year follow-up.
Methods:
Male patients who underwent hip resurfacing or THA between 2008-2015 were matched using propensity scores to ensure comparable groups. Functional outcomes were assessed, including the Forgotten Joint Score.
Key Findings:
- Five-year patient-reported outcomes after hip resurfacing were similar to those following either THA approach.
- No significant differences in functional scores were found between groups.
Conclusions:
Hip resurfacing offers comparable long-term functional results to THA and may be an appropriate option for younger, active patients.
What Does This Mean for Providers:
- Hip resurfacing remains a viable option for younger, active male patients seeking hip arthroplasty.
- Use propensity matching to better assess comparative outcomes in clinical studies.
- Consider patient preference, anatomy, and surgeon experience when recommending resurfacing vs. THA.
- Counsel patients on comparable long-term outcomes between resurfacing and THA.
