Does hip resurfacing arthroplasty reduce early revision rates compared to conventional total hip arthroplasty in patients undergoing hip replacement?
Hip resurfacing arthroplasty is associated with a significantly higher risk of early aseptic revision compared to conventional total hip arthroplasty, particularly in women and older men.
Johanson et al. (2010) studied this question.
