Knee Arthroplasty for Ankylosis in a Patient with Severe Hemophilia A.

Hemophilic arthropathy is a common complication of hemophilia A and can lead to chronic synovitis, joint damage, and eventually ankylosis. We present a case report of a 39-year-old male patient with a history of recurrent hemorrhages into the joints. He had a history of traumatic injury to both upper limbs and lower limbs. The patient was on bed rest for 6 months. Subsequently, he developed ankylosis of both elbows in 30° of flexion and ankylosis of the right (Right) knee in 40° of flexion with tricompartmental arthritis of the left knee joint. Radiologically, the left knee joint showed reduced joint space with tricompartmental arthritis. The patient was managed by the tumor prosthesis for the Rt knee. He was advised for management of the elbow joints for which he was not willing. Postoperatively, he was allowed knee range of motion exercises and walking with a walker for 4 weeks followed by a stick for 1 month. At 6-month follow-up, he was able to walk effortlessly without support. The Knee Society Score improved from 47 preoperatively to 75 at 6-month follow-up. [ABSTRACT FROM AUTHOR]
