[Prosthetic management of rotation-plasties according to Borggreve].

Two patients, suffering from Osteosarcoma of the distal femur, were operated in 1987. A Rotatoryplasty with resecting the half of the femur and the knee joint was performed. We would like to demonstrate our experiences in the prosthetic fitting in these patients. The Rotatoryplasty improves the prosthetic comfort in these patients cured by above knee amputation in former time.
