Outcome of Primary Total Hip Arthroplasty in Charnley Class C Patients with Juvenile Idiopathic Arthritis A Case Series JOURNAL OF ARTHROPLASTY De Ranieri, A., Wagner, N., Imrie, S. N., Hwang, K. L., Goodman, S. B. 2011; 26 (8): 1182-1188


The outcome and complications of 37 primary total hip arthroplasties by one surgeon in 24 patients with Charnley Class C juvenile idiopathic arthritis with up to 19.6 years follow-up are reported. Twenty-six femoral components were cementless; all acetabular components were cementless with screws. Age at operation averaged 22.6 years. Two patients (3 hips) have died. Twelve hips in 9 patients have failed. Six cementless acetabular components with conventional polyethylene were revised because of osteolysis after 5.5 to 14.5 years. All 3 cementless C2 femoral stems with minimal porous coating failed. One of eight cemented AML Bantam stems loosened at 3.5 years; 2 of 23 cementless AML Bantam stems loosened at 9.5 and 19.6 years. Pain relief and functional improvement are dramatic after total hip arthroplasty in juvenile idiopathic arthritis; however, the long-term outcome is guarded.
