title: The 27 to 29-year outcomes of the PCA total hip arthroplasty in patients younger than 50 years old.
abstract: 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 27-29years. Eighty-eight consecutive primary THAs using a PCA total hip system were performed in 70 patients (mean age, 45.6±11.1years). The mean follow-up was 28.4years (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±0.03mm. There were 75 acetabular (85%) and 40 femoral (45%) osteolysis. The rate of survival after 28.4years as the end point of revision was 66% for the acetabular component and 90% for the femoral component.
