A tumor endoprosthesis is useful in elderly rheumatoid arthritis patient with acute intercondylar fracture of the distal femur.

The purpose of this paper is to report the use of total knee arthroplasty using a tumor prosthesis in the treatment of elderly patients with an intercondylar fracture of the distal femur. Supracondylar fractures of the femur in patients with rheumatoid arthritis are difficult to treat due to joint deformity. We present outcomes for treating intercondylar fractures of the distal femur in rheumatoid arthritis patient using a tumor endoprosthesis. This technique allows early mobilization of the patient, with restoration of a good range of knee motion. A tumor prosthesis appears to be a viable treatment option for intercondylar femoral fractures in elderly patients. It is well tolerated and permits early ambulation and return to activities of daily living.
