Two types of prostheses — transtibial and transfemoral — are used to replace a missing leg. Transtibial prosthetics are used to replace parts missing below the knee. Transfemoral prosthetics include an artificial knee joint and attach to the thigh.
In practice, there are four common types of prosthetic limb, which replace either a partial or complete loss of an arm or leg: Below the knee (BK, transtibial): An prosthetic lower leg attached to an intact upper leg. Above the knee (AK, transfemoral): A prosthetic lower and upper leg, including a prosthetic knee.
