title: Ender nailing for supracondylar fracture of the femur after total knee arthroplasty: five case reports.
abstract: We studied 5 women with supracondylar fractures after total knee arthroplasty (TKA). The mean age at fracture was 67.4 years. Four patients had chronic rheumatoid arthritis, and 1 had osteoarthritis. The range of motion, knee score, femorotibial angle, and component alignment were investigated. Flexion was slightly decreased after Ender nailing, but extension only changed in 1 patient. The knee score decreased, but all patients were ambulatory. The femorotibial angle changed in all patients. Measurement of femoral component alignment showed a postoperative change of angle alpha (1 degrees to 11 degrees ) and angle gamma (0 degrees to 9 degrees ). Union was achieved in all patients. Ender nailing is an acceptable method of treatment for supracondylar fractures of the femur after TKA if the nails can be inserted deeply into the femoral condyles.
