ABSTRACT
PURPOSE:
The purpose of this study was to evaluate the outcomes of total hip arthroplasty (THA) with an ABG I hip prosthesis after a minimum ten-year follow up. MATERIALS ANDMETHODS:
From January 1996 to March 2001, 121 hips in 104 patients, whi were followed up for a minimum of ten-years, were enrolled in this study. The clinical and radiographic outcomes were evaluated and Kaplan-Meier survival analysis was performed.RESULTS:
The mean Harris hip score at the last follow-up was 84 points. A radiolucent line around the cup, osteolysis, and cup loosening were observed in 5 hips(4.1%), 53 hips(43.8%), and 5 hips(4.1%), respectively. In the femoral side, osteolysis and stem loosening were observed in 11 hips(9.1%) and 2 hips(1.7%), respectively. The mean linear wear rate of the polyethylene liner was 0.23 mm/yr. Forty four revisions(36.3%) were performed. The outcomes were similar regardless of the cause of primary THA. The survival rate with the end point of revision due to cup loosening was 56.3%, and revision due to stem loosening was 98.1% after a 16 year follow-up.CONCLUSION:
High polyethylene wear and the disappointing survival rate of the ABGI cup were observed after a minimum ten year follow-up. Therefore, close observation of patients who have received an ABG I prosthesis is necessary.
