Synovectomy for haemophilic arthropathy: 6–21 years of follow-up in 16 patients

Abstract. Objectives . To assess the efficacy of synovectomy in reducing recurrent haemarthroses and joint pain in patients suffering from haemophilic arthropathy. Moreover, to study whether synovectomy could improve joint mobility or postpone progression of joint destruction. Design . A retrospective study was conducted addressing joint-related symptoms and findings, and the need of orthopaedic surgery during follow-up. Setting . Oslo Sanitetsforenings Rheumatism Hospital/The National Hospital, the National Centre for Orthopaedic Surgery for approximately 180 Norwegians suffering from severe congenital coagulation deficiencies. Subjects . Twelve patients with haemophilia A, two patients with von Willebrand's disease and two patients with factor VII deficiency in which 21 synovectomies (nine knees. six ankles and six elbows) were performed. Main outcome measures . Joint pain, joint mobility, frequency of haemarthroses and radiographic joint scores at follow-up were compared to preoperative figures, and the number of joints in need of total joint replacement or arthrodesis was evaluated. Results . Synovectomy proved efficacious in reducing recurrent haemarthroses and joint pain in all patients. The total range of motion was not improved, but correction of extension deficiency of the knee was accomplished. The progression of arthropathy was not arrested by synovectomy as judged by the radiographic assessment; and in four patients arthroplasty of the knee, and in two patients arthrodesis of the ankle, had been performed. A major wound haemorrhage and subsequent wound rupture was seen in one patient who developed high-titred neutralizing antibodies to factor VIII. Conclusions . Synovectomy for haemophilic arthropathy is safe and efficacious in reducing recurrent haemarthroses and joint pain. Synovectomy should not be performed to improve joint mobility. The progression of the arthropathy is not arrested, and subsequently many patients will be candidates for arthroplasty or arthrodesis.
