A 18-year-old man with hemophilia A complainted of pain, snapping and occasional locking of his right knee. The knee was found to be slightly swollen, to test positive with a McMurray test on the lateral meniscus and to have an atrophied quadriceps. The range of motion was from 10°to 150°. Roentogenograms showed enlargement of the intercondylar fossa, narrowing of the joint space, cyst formation and bone destruction. Under arthroscopy a bucket-handle tear in the lateral meniscus was found and subtotal meniscectomy was performed.
Replacement therapy of factor VIII concentrates was done before, during and after the surgery. The patient was injected with 15000 units of facter VIII concentrates in all and discharged 8 days after operation. Thus arthroscopic meniscectomy proved effective, for bleeding was well controlled using facter VIII concentrates. The patient only had to have a short admission, though he had had the HIV antibody due to the replacement therapy of facter VIII concentrates since 4 months of age. Much of the success was also due to the cooperation of doctors and other staff during his admission.
