The diagnoses were idiopathic osteoarthritis (n=121), osteonecrosis of the femoral head (n=25), rheumatoid arthritis (n=14), and post-traumatic osteoarthritis (n=8). Patients were evaluated clinically and radiographically before and after THA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>The mean Harris hip score improved from 40 to 84 (p&lt;0.001); the score was excellent or good in 130 hips, fair in 17, and poor in 21. The mean Merle D'Aubigne score improved from 4 to 10 (p&lt;0.001); the score was excellent or good in 138 hips, fair in 9, and poor in 21. Poor results were due to aseptic revision of the cup (n=16) or stem (n=3) or deep infection (n=2). Thigh pain that limited activities of daily living was noted in 3 hips. 142 patients could walk without a limp, 5 had a slight limp, and 3 had a moderate limp and used a cane. The mean Short Form-12 score for the physical function was 49 and for the mental health was 56; the mean Western Ontario and McMaster Universities Osteoarthritis Index was 39; the mean visual analogue scale score for satisfaction was 8. Two patients developed deep infection at postoperative months 8 and 50 and were treated with 2-staged revision. Five patients had hip dislocation within 2 months; 3 of whom endured recurrent dislocation and underwent revision surgery; they had acetabular malposition with excessive anteversion despite a correct acetabular angle. 13 other cups were revised because of loosening or extensive osteolysis (n=10) and polyethylene wear (n=3) after a mean interval of 6 (range, 4\u201310) years. Three stems were revised because of aseptic loosening after a mean interval of 7 (range, 6\u20139) years. The survivorship at 14 years was 99% for stems and 91% for cups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n
