Description

The PTB prosthesis is usually suitable for 90% of amputees with below the knee amputations. The PTB prosthesis is based on transferring load through the patella tendon (tendon below the knee), the tibial condyles (upper extremity of the shin bone) and a large portion of the stump. The most common error made when fitting a PTB is an exceedingly tight fit around the popliteal area (hollow behind the knee joint) of the stump which can lead to excessive oedema, reduced circulation and skin irritation.
