Health-related quality of life (HRQOL) of systemic lupus erythematosus (SLE) patients with hip arthroplasty after medium to long-term follow-up has not been reported. We conducted a retrospective study for SLE patients with osteonecrosis of the femoral head (ONF). Forty-seven consecutive arthroplasties were performed in 36 patients. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Medical Outcome Survey Short Form 36 (SF-36) and Harris hip score were evaluated. Two patients died before the four-year follow-up and two patients were lost to follow-up. The remaining 43 hips in 32 patients with an average age at surgery of 35 years and an average follow-up of 12.0 years (range 4.0—25.0) were assessed. Bipolar hemiarthroplasty was performed for 18 hips in 12 patients, and total hip arthroplasty (THA) was performed for 25 hips in 20 patients. The mean WOMAC scores for pain and function at the recent followup were 90.8 ± 8.5points and 79.0 ± 18.3 points. Patients with THA had significantly high scores in SF-36 physical functioning (P < 0.05) and bodily pain (P < 0.03) compared to those with bipolar hemiarthroplasty. Although improvement could not reach the level of general population, the hip arthroplasty contributed to support HRQOL of SLE patients. Lupus (2007) 16, 1—6.

Key Words: health-related quality of life (HRQOL) • hip arthroplasty • osteonecrosis of the femoral head (ONF) • systemic lupus erythematosus (SLE)
