Typically applied in cases of osteosarcoma and congenital abnormalities in the lower leg, Van Nes or Rotationplasty replaces the knee joint with the patient’s ankle joint – the foot is rotated 180º, the length is adjusted, and the tibia is then fused to the proximal femur. This creates a potential for increased mobility compared to an above-knee amputation.
However, taking full advantage of the benefits of a rotationplasty requires a prosthetist who has vast experience with Van Nes patients and their needs. The rotationplasty prosthesis is radically different than a typical leg prosthesis, as it is designed around the patient’s reversed foot/ankle. A Step Ahead has worked with dozens of recipients of this uncommon procedure and is currently considered the leader in fabricating and fitting prostheses for Van Nes Rotationplasties.
