These prostheses are a specialty style prosthesis that require inclusion of the foot in the structure of the prosthesis to accommodate the unique structure associated with having an intact ankle to control the prosthesis. The foot is the structure that is attached to the prosthesis.
In the case of the Rotationplasty prosthesis, the prosthesis will also include an external knee joint to help support the remaining ankle structure that will now be used for the patient's knee during ambulation. The natural ankle will work along with the prosthetic knee joint to control the prosthesis.
The goal is to return a individual to the daily activities performed and enjoyed prior to the amputation.
