Orthopedic surgical procedures in people with hemophilia

Abstract

People with hemophilia tend to develop joint lesions secondary to the recurrent hemarthroses typical of their condition. These usually include chronic synovitis and arthropathy chiefly affecting their ankles, knees, and elbows. In addition, muscular hematomas, albeit less frequently, may also result in complications such as acute compartment syndrome, pseudotumors, bone cysts and peripheral nerve compression. Joint lesions may require some of the following surgical interventions: arthroscopic synovectomy (in cases of synovitis), arthroscopic joint debridement, radial head resection, opening-wedge tibial osteotomy, arthrodesis, arthrodiastasis (of the ankle), tendon lengthening (hamstrings, Achilles tendon), progressive extension of the knee by placing an external fixator in cases of flexion contracture of the knee, supracondylar femoral extension osteotomy in cases of knee flexion contracture and, eventually, a total joint arthroplasty when the affected joint has been destroyed and the patient experiences severe joint pain. Total knee arthroplasty in hemophilic patients is associated with a high infection risk (7% on average). As regards the complications following muscle hematomas, acute compartment syndrome requires urgent performance of a fasciotomy when hematological treatment is incapable of resolving the problem. Surgical resection of hemophilic pseudotumors is the best solution, with those affecting the pelvis (secondary to iliopsoas hematomas) being particularly difficult to resolve. Peripheral nerve lesions can often be effectively addressed with hematological treatment, although a surgical neurolysis of the ulnar nerve is indicated if nonoperative treatment fails.
