ARTHROPLASTY
Metal-on-Metal Hip Resurfacing vs. Large head THA on quality of life and serum ion levels
Clin Orthop Relat Res. 2010 Feb;468(2):318-25.

At a mean 1.1 year follow up, both metal-on-metal hip resurfacing and metal-on-metal THA resulted in higher quality of life on all outcome measures compared to baseline. However, the level of chromium ions was significantly higher in patients treated with large head metal-on-metal THA.
