Objective  To investigate the clinical outcomes of total knee arthroplasty (TKA) by using the condylar constrained knee prosthesis in the treatment of destructive hemophilic arthritis. Methods  Between September 2007 and July 2015, 8 cases (8 knees) of destructive hemophilic arthritis accepted TKA by using condylar constrained knee prosthesis. All patients were male, aged 22 to 56 years, with an average age of 35 years. The disease course of hemophilia A was 3-30 years (mean, 17.3 years). Preoperative range of motion (ROM) was (68.1±32.6)°; the flexion deformity was (14.38±16.13)°. Six patients had valgus of 7-35° (mean, 17.3°), of whom, one had fixed dislocation of patella; and one had varus of 15°. Hospital for Special Surgery (HSS) knee score was 52.5±12.9. Pre-operative X-ray film examination demonstrated narrowing of the knee gap and cystic degeneration of articular cartilage and subchondral bone. Results  All patients achieved primary wound healing, and were followed up 1-9 years (mean, 5 years). Tense blister with common peroneal nerve damage and extension penetrating into distal tibial cortex occurred in 1 case respectively, which were cured corresponding treatment. At last follow-up, the knee ROM and the flexion deformity were significantly improved to (98.1±8.9)° and (0.63±1.77)° (t=–2.527,P=0.036;t=2.396,P=0.047). At 2 weeks after operation and last follow-up, the HSS scores were significantly increased to 77.3±11.0 and 85.0±9.0 (P<0.05). X-ray film showed that lower extremity alignment returned to normal in patients with varus and valgus. Conclusion  Good curative effect can be get by using condylar constrained knee prosthesis in TKA for the treatment of destructive hemophilic arthritis.
