Although total knee arthroplasty ( TKA ) in haemophilic arthropathy can reduce severe joint pain and improve functional disability, it is technically demanding. Aim To evaluate mid‐term outcomes and complications of TKA in haemophilic arthropathy. Methods This study retrospectively reviewed 131 consecutive primary TKA s in a single institute. The mean age was 41.0 years old, and the mean follow‐up period was 6.8 years. Clinical and radiographic results were evaluated. Complications were categorized according to the classification system of the Knee Society for TKA complications. Results The average Western Ontario and McMaster Universities Arthritis Index ( WOMAC ) score improved from 66.0 to 24.2. The average flexion contracture significantly decreased from 17.3° to 4.7°, but the average pre‐ and postoperative maximum flexion did not differ (80.9° vs 85.6°, respectively). The average mechanical axis was varus 5.2° preoperatively and valgus 0.3° postoperatively. The coronal positions of the femoral and tibial components and the sagittal positions of these components were within ±3° in 83.2%, 89.3%, 63.4% and 73.3% of cases, respectively. Complications occurred in 17 knees (13.0%): hemarthrosis (n = 7), medial collateral ligament injury (n = 1), stiffness (n = 2), deep periprosthetic joint infection (PJI) (n = 3) and periprosthetic fracture (n = 4). Conclusions The mid‐term results of TKA in haemophilic arthropathy were satisfactory in pain relief, improved function and decreased flexion contracture. Bleeding and PJI continue to be major concerns for TKA in haemophilic arthropathy, and risk of periprosthetic fracture must be taken into account for patient education and appropriate prevention.
