Purpose of Technology
Hip resurfacing arthroplasty (HRA) has been proposed as an alternative to total hip replacement (THR) for the treatment of young (age ≤ 65 years), active patients who have radiographic evidence of joint damage and/or chronic pain or disability that interferes with daily activities and is refractory to conservative treatment. HRA involves the removal and replacement of the surface of the femoral head with a hollow metal hemisphere that fits into a metal cup inserted into the acetabulum of the pelvis.
