Summary
Metal-on-metal hip resurfacing offers excellent long-term implant survivorship, especially for males, with high patient satisfaction. This hip surgery alternative demonstrates durable results at a minimum 10-year follow-up.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Metal-on-metal hip resurfacing serves as an alternative to traditional total hip arthroplasty (THA).
- Evaluating long-term outcomes is crucial for understanding the efficacy of hip resurfacing implants.
Purpose of the Study:
- To assess implant survivorship and patient-reported outcomes for metal-on-metal hip resurfacing.
- To determine patient satisfaction following hip resurfacing surgery with a minimum 10-year follow-up.
Main Methods:
- Retrospective analysis of patients who underwent hip resurfacing between 2006 and 2009.
- Data collection included patient demographics, surgical variables, and patient-reported outcomes measures via questionnaires.
Main Results:
- High implant survivorship (96.9%) with a 94.3% follow-up rate at 10 years.
- Male patients demonstrated significantly higher survivorship (99.0% vs. 90.9%) and satisfaction.
- Satisfied patients (94.8%) reported higher functional scores (modified Harris Hip Score).
Conclusions:
- Metal-on-metal hip resurfacing shows excellent survivorship and patient satisfaction at a minimum 10-year follow-up.
- The procedure is a viable option for select patients, particularly males, based on long-term outcomes.
