Dr. Gross has now performed over 2500 Hip Surface Replacement (HSR) procedures over the last 12 years. Most failures occur during the first 6 months of the healing period. However, there is a slow rate of failure that occurs over time. Therefore the overall failure rate increases for a group of patients as the length of follow-up increases.
A steep acetabular inclination angle is the primary cause of adverse wear related failure with well-designed metal-on-metal bearing hip resurfacing arthroplasties (HRA). One recent study demonstrated that positioning acetabular components of stemmed total hip arthroplasties (THA) within the “Lewinnek safe zone” is difficult; only 62% had AIA within the safe zone.
