The 27 to 29-Year Outcomes of the PCA Total Hip Arthroplasty in Patients Younger Than 50 Years Old

We previously reported our six and 19.4-year results of arthroplasty with the PCA total hip prosthesis. We now report on the performance of this prosthesis at 27-29 years. Eighty-eight consecutive primary THAs using a PCA total hip system were performed in 70 patients (mean age, 45.6 ± 11.1 years). The mean follow-up was 28.4 years (27-29). The mean Harris hip score was 89 points at final follow-up. Thigh pain was reported in 22 hips (25%). The mean annual polyethylene wear was 0.182 ± 0.03 mm. There were 75 acetabular (85%) and 40 femoral (45%) osteolysis. The rate of survival after 28.4 years as the end point of revision was 66% for the acetabular component and 90% for the femoral component.
