Comparative Effectiveness of Metal-On-Metal and Metal-On-Polyethylene Bearings in Medicare Total Hip Arthroplasty Patients
Journal of Arthroplasty, 05/30/2012
Bozic KJ et al. – Overall short–term revision rates did not vary significantly across bearing types, consistent with registry data. The benefits of hard–on–hard bearings in Medicare patients remain unproven, and further study is needed to compare long–term complication and revision rates in Medicare total hip arthroplasty patients with different bearing types.
