Differences in postoperative QoL
Femoral head resurfacing versus a large femoral head (Durom
) Total Hip System: A prospective randomized trial.
Project Goals - What are we doing?
To estimate the difference in postoperative quality of life (QoL) at 2 years between patients with Durom hip resurfacing versus those with THA using a large-head, metal-on-metal articulation.
Research Outcomes - What will be achieved?
The development of minimally invasive surgery techniques that result in decreased recovery time after surgery may provide insight into cost-saving techniques.
Background - Why is this research important?
Hip resurfacing arthroplasty involves minimal resection of host bone and tissue and therefore is considered by some to be a conservative bone-preserving arthroplasty for patients with advanced osteoarthritis. The large bearing surface results in improved range of motion and contributes to increased prosthetic joint stability. The metal on metal articulation has the potential to decrease wear and ultimately to reduce the incidence of implant failure. Early clinical results with these new designs have been favourable. Unpublished dislocation rates are said to be less than 0.05% in 5-year follow-up. Its proponents argue that retention of the femoral head is critical for success as it allows normal proprioception.
