The purpose of the current study was to update the results of a prospective, single-surgeon series of primary Charnley total hip arthroplasties performed with cement. This investigation is one of the first studies in which hips treated with total hip arthroplasty with cement were followed for a minimum of 30 years. 27 patients (34 [10.3%] of the hips in the initial study group) were alive at a minimum of 30 years postoperatively. These patients served as the focus of the present study. Revision because of aseptic loosening of the acetabular component was performed in 7.3% (23) of the hips from the original study group (excluding those revised because of infection or dislocation) and 26% (8) of the hips in the living cohort. Revision because of aseptic loosening of the femoral component was performed in 3.2% (10) of the hips from the original study group (excluding those revised because of infection or dislocation) and 10% (3) of the hips in the living patients. Since the 25-year review, 3 hips were revised (one because of acetabular loosening, one because of femoral loosening, and one because of instability). This end-result study demonstrated the remarkable durability of cemented Charnley total hip replacements over a span of 3 decades, with 88% of the original prostheses intact at the time of the final follow-up or at the patient's death.
