Core Tip

Core Tip: We aim to examine the “revisability” benefit of hip resurfacing arthroplasty (HRA): Are outcomes of conversion to total hip arthroplasty (THA) after failed metal-on-metal-HRA worse compared to primary THA? This study expands the literature by examining patient reported outcomes between HRA revision and primary THA, and outcomes between HRA revision and revision THA. HRA patients revised to THA have worse clinical outcomes compared to primary THA and the outcome is dependent on the etiology of failure.
