Abstract
BACKGROUND: Haemophilia is characterized by a partial or complete deficiency of clotting factor VIII or IX. The repeated bleeding episodes into the joints contributes to subsequent chronic arthropathy which debilitates the patient and affects the quality of life. There are lot of hurdles in successful management of such patients. We present our experience in dealing such patients. MATERIALS AND METHODS: 24 patients (27 knees) with haemophilic knee arthropathy were included. The preoperative VAS (Visual Analogue Scale) and KSS (Knee Society Score) were assessed. All underwent total knee arthroplasty with stemmed constrained prosthesis. Postoperatively VAS and KSS were analysed at the end of 12 months. RESULTS: The mean preoperative VAS was 8.2 (Range: 7-10), mean KSS clinical score was 39.9 (Range: 12-61) and mean KSS functional score was 51.4(Range: 20-70). The mean postoperative VAS was 2.7(Range: 2-4), mean KSS clinical score was 70.5 (Range: 61-80) and mean KSS functional score was 74.2(Range: 60-80). There was statistical significant difference between preoperative and post-operative scores. At the end of 12 months, 17 patients (63%) had good outcome, seven patients (26%) had fair and three patients (11%) had excellent outcome as per the KSS scores. CONCLUSIONS: Total knee arthroplasty has good outcome with respect to clinical as well as functional outcome in haemophilic arthropathy. Although the results and outcome of total knee arthroplasty in haemophilic knee arthropathy may still be inferior to the results seen in a normal individual, a multidisciplinary approach yields a better functional and quality of living in such haemophilic patients.
