| Abstract | INTRODUCTION Polyethylene wear remains a leading cause of osteolysis, aseptic prosthetic loosening, and subsequent failure in total hip arthroplasty (THA). Pre-clinical wear testing of acetabular liners has been a useful tool to predict clinical outcomes. Wear studies have investigated the impact of various materials, prosthetic designs, and sizes of the femoral head and acetabular cup couples. However, less testing has been performed on the effects of surgical malpositioning of the acetabular component, which is also thought to play an important role in the production of wear [1-5]. Inherent in these studies of component positioning are multiple variables that, in addition to abduction angle, can effect wear or wear measurements; i.e. cup migration, cup anteversion, and creep. These variables can be predictably controlled and studied in vitro settings. The objective of this study was to isolate and examine the effects of varying cup abduction angles on polyethylene wear. |
