Popis:	Fifty-three hips of 49 patients were available for the study.All of them had received clinical and radiological examinations twice annually or annually.Their mean age at surgery was 57 years. The average postoperative period was 17.8 years, ranging from 14 to 26.2 years. Diagnosis at the time of surgery was 48 cases of osteoarthritis, 2 cases of rheumatoid arthritis, 2 cases of osteonecrosis of the femoral head, and 1 case of femoral neck fracture. Clinical results were evaluated using the JOA scoring system; radiological evaluation was performed by Charnley's method on the acetabular side, and Nagaya's method on the femoral side. The preoperative JOA score of 44 points improved to 84.3 points after one year postoperatively, remained at 77.5 points after 15 years and at 78.5 points for over 20 years.Radiologically, G4 showing migration of the socket was recognized in 10% of the patients after 10 years and in 17% after 20 years. Stage 4 showing subsidence of the stem was recognized in 4% after 10 years and in more than 4% in 15 years. Revision surgery was performed on 9 hips.
