Quality of life after TKA for patients with juvenile rheumatoid arthritis.

UNLABELLED: Total knee arthroplasty frequently is required during early adulthood in patients with advanced juvenile rheumatoid arthritis. We queried patients on issues of importance to them, asked whether they were satisfied with surgical outcomes, and ascertained their postoperative status. We retrospectively reviewed 14 adult patients (22 knees) with severe juvenile rheumatoid arthritis who were treated with primary total knee arthroplasty between 1989 and 2001. All patients were evaluated by pain and stiffness visual analog scales, range of motion, the Patient-Specific Index, Hospital for Special Surgery knee score, WOMAC Osteoarthritis Index, EuroQuol in five dimensions, and SF-36 Health Survey. Preoperative scores were assessed by recall. Patients had a minimum followup of 2 years (mean, 8 years; range, 2-13 years). Quality of life improved after TKA as measured by the Patient-Specific Index. Eighteen of 22 patients rated themselves satisfied with the functional outcome of their surgery; all patients were satisfied with pain relief. Final SF-36, EuroQuol in five dimensions, and WOMAC scores were low compared with age-matched population norms. A mean postoperative flexion arc of 77 degrees (range, 30 degrees -130 degrees ) was observed. Total knee arthroplasty had a major positive impact on quality of life as reported by patients. LEVEL OF EVIDENCE: Level IV, therapeutic study.
