This retrospective, consecutive case series of a single surgeon performed between 2001 and 2010 assesses the outcome following revision of metal-on-metal hip resurfacing arthroplasties (N = 113). Mean time to revision was 31 months (0-101) ...
A prospective metal ion study of large-head metal-on-metal bearing: a matched-pair analysis of hip resurfacing versus total hip replacement [0.03%]
大直径金属对金属髋关节假体的前瞻性金属离子研究：髋关节置换与髋关节表面置换的配对分析
