Abstract:
From January 1996 to January 2001, arthroscopic synovectomies were performed in 28 knees with haemophilic arthropathy. The mean follow-up period was 5 years and 11 months. Six portals (two anterior, two suprapatellar, two posterior) and a posterior trans-septal portal were used in all cases. The average Hospital for Special Surgery (HSS) knee score increased from 56.4 to 71.5 points at the last follow-up. The average frequency of haemarthrosis reduced from five times per month before operation to once per month. The amount of factor replacement decreased from a mean of 4,633 U to 1,505 U. Progression of arthritis was observed radiographically in three cases at the last follow-up. An arthroscopic synovectomy of the knee using appropriate arthroscopic portals is a useful method in treating haemophilic patients as it decreases bleeding episodes, amount of factor replacement and knee pain.
