Clinical results of Harris-Galante total hip arthroplasty without cement. Follow-up study of over five years.
Sixty-eight primary total hip arthroplasty in sixty-two patients (average age: 56.2 years) were followed for a minimum of five years (mean: 7.3 years). In all patients a Harris-Galante prosthesis was used. The initial diagnosis was osteoarthritis in 65 hips and avascular necrosis in 3 hips. Forty hips (58.8%) had high degree acetabular dysplasia that necessitated performing autogenous femoral head bone grafting. Preoperatively, the mean Harris hip score was 53.1 points. At last follow-up the mean hip score was 91.2 points. Twelve patients (17.6%) complained of thigh pain, which disappeared within two years in ten hips. Two patients complained of mild thigh pain of more than two years duration. There were no limitations of the activities of daily living. Radiolucency at the component-bone interface were graded 30.9% on the acetabular side, and 64.7% on femoral side. In all cases the radiolucencies were less than 2 mm in width. Two femoral components were graded as loose, but no acetabular component was graded as loose. The extrusion of the acetabular liner was seen in one hip, which is considered to be a fatigue breakage due to its design. The authors conclude that cementless total hip arthroplasty in Japan has presented excellent results.
