Hip Resurfacing Arthroplasty
Bone-conserving alternative to THA; resurfaces femoral head with metal cap. Indicated in young, active patients with OA, good bone stock, large femoral head size. Advantages: bone preservation, easier conversion to THA, lower dislocation risk. Complications: femoral neck fracture, aseptic loosening, metal ion release (cobalt/chromium). Decline in popularity due to metal-on-metal concerns; selected patients may still benefit.
