Long-term results of total hip arthroplasty in patients with juvenile rheumatoid arthritis
Abstract
Methods: The study included 37 hips of 23 patients (22 females, 1 male; mean age 22 years; range 17 to 30 years) who underwent THA for hip degeneration secondary to JRA. All arthroplasties were performed through an anterolateral approach by the same senior surgeon. The mean body surface of the patients was 1.5 m² (range 1.1 to 1.7 m²) and the mean symptom duration to surgery was 12 years (range 7 to 16 years). Twenty-three hips received cemented, 14 hips received hybrid prostheses. In seven hips with an extremely narrow femoral medulla and shallow acetabulum, a CDH prosthesis was used. The hips were evaluated using the Harris hip score. Prosthetic loosening and displacement and heterotopic bone formation were assessed on follow-up radiographs. The mean follow-up period was 135 months (range 58 to 212 months).
Results: The mean Harris hip score increased from 27.2 (range 11 to 69) to 79.5 (range 37 to 87) postoperatively. At final follow-ups, all the patients were satisfied with the outcome and were able to walk without support. Three hips (8.1%; 3 patients) required revision. The overall Kaplan-Meier implant survival rate was 86.5%. There were no significant correlations between the Harris hip score and radiographic loosening and the presence of calcification around the prosthesis. Heterotopic bone formation of grade I was observed in 17 hips (46%).
Conclusion: Even though it is performed at young ages, THA considerably improves quality of life of patients with JRA having hip joint involvement and has a comparable implant survival.
