Summary
Second-generation hip resurfacing devices show high survivorship (95-99.7%) in selected patients. Ongoing evolution focuses on implant design and fixation to improve outcomes for hip replacement surgery.
Area of Science:
- Orthopedic surgery
- Biomaterials science
Background:
- Hip resurfacing was designed for young, active patients to preserve bone stock.
- Concerns regarding metal-on-metal bearings and adverse reactions have decreased hip resurfacing procedures.
Purpose of the Study:
- Evaluate survivorship of second-generation hip resurfacing devices.
- Elaborate international perspectives for product improvement.
Main Methods:
- Comprehensive literature search of national joint arthroplasty registers.
- Analysis of six registers with a minimum of 3000 reported hip resurfacings.
Main Results:
- Long-term survivorship ranged from 95% to 99.7% at 10 years in selected populations.
- Success factors include male gender, good bone quality, large head size (>48mm), and specific cup inclination (<45°).
- Device recalls led to evolution, with new cemented/cementless fixation and potential for ceramic-on-ceramic, polyethylene, or oxinium bearings.
Conclusions:
- Hip resurfacing continues to evolve in implant design, bearing materials, and fixation methods.
- The goal is to enhance survivorship and address past concerns.
