We report here on the efficacy and safety of three arthroscopic procedures using a Holmium: Yag laser in two high-responder haemophiliacs. The two patients were treated with an activated prothrombin complex concentrate (FEIBA; Immuno, Vienna, Austria). Treatment was started just before surgery and continued for 4-8 days. On one occasion antifibrinolytics were concomitantly used without thromboembolic complication. Post-operative blood loss was slight, joint mobility was rapidly acceptable and full weight bearing without pain was possible on day 4. Such a procedure would appear to be superior to conventional arthroscopic synovectomy utilizing mechanical devices in haemophiliacs, because it might improve the quality of local haemostasis and the rapidity of post-operative recovery. In addition, it is also the technical procedure of choice in haemophilic patients with inhibitors who need synovectomy.
