The role of synovectomy in the management of recurrent haemarthroses in haemophilia.
Between August 1973 and May 1979, 18 patients suffering from severe haemophilia A underwent synovectomy for recurrent haemarthroses, resistant to medical management. A total of 23 joints (11 knees and 12 elbows) were subjected to operation, five patients undergoing two synovectomies on different joints. Post-operative follow-up period ranged from 12 to 58 months for elbow synovectomy and from 29 to 76 months for knee synovectomy. All patients experienced fewer haemarthroses, the average number of bleeding episodes per joint over a 12 month period being reduced from 19 to 3 for knee joints, and from 24 to 3 for elbow joints. This improvement was apparent in the immediate post-operative year and maintained thereafter. Over the same follow-up period nine of the 11 knee joints were found to have lost an average 42 degrees mobility. Following elbow synovectomy five out of 12 patients lost an average of 28 degrees mobility; six patients gained an average 11 degrees mobility. The post-operative complication rate was high for knee synovectomy, 54% suffering haemorrhage despite haemostatic factor VIII levels. For elbow synovectomy the rate was much lower, 75% of operations being uncomplicated. The average in-patient time for knee operation was 75 d, and for the elbow 19 d. We conclude that synovectomy of the knee joint is to be avoided when other means of reducing bleeding episodes are available, whereas elbow synovectomy retains a useful role in the treatment of recurrent haemarthroses which do not respond to clotting factor prophylaxis.
