Viscosupplementation in patients with hemophilic arthropathy

OBJECTIVE: To assess whether viscosupplementation with hyaluronic acid in patients with severe hemophilic arthropathy associated with triamcinolone after washing with saline improves joint pain, stiffness, function and quality of life. METHODS: Eleven patients with hemophilic arthritis of the knee with and without involvement of other joints (elbows and ankles) underwent joint lavage with saline and subsequent injection of Hylan and triamcinolone in all affected joints. The patients answered the algo-functional (Lequesne and WOMAC), visual analog scale for pain (VAS) and SF-36 (quality of life) questionnaires preoperatively, and at one and three months postoperatively. RESULTS: Pain (VAS and WOMAC pain) and stiffness (WOMAC stiffness) did not show significant improvement (p = 0.3, p = 0.2, p = 0.1, respectively). However function had significant improvement given by WOMAC total and function (averaging 11 points, p = 0.04 and p = 0.001). There was no significant variation in scores in Lequesne's questionnaire (p = 0.1), yet both mental and physical components of SF-36 presented clinically relevant and significant improvements (p = 0.002). CONCLUSION: Joint lavage with saline followed by injection of corticosteroids and Hylan is effective in the treatment of hemophilic arthropathy, especially in functional improvement and quality of life.
