Acetabular cup wear in total hip arthroplasty.
Clinical, pathologic, radiographic, and biomechanical factors of 10 severely worn retrieved Charnley acetabular cups were examined to determine whether these factors influenced cup wear. Change in cup thickness was found to be linear with time. It was found that the actual change in cup thickness was not significantly different from the radiographic change in cup thickness. No correlation was found with the other clinical or radiographic factors.
