What are the different types of prosthetic knees?

What are the advantages and disadvantages of plastic knee prosthesis?

This type of prosthesis helps replicate the small amount of rotation that a normal knee experiences when becoming fully extended. Another advantage is that there may be less shear stress on the top of the plastic, where the femoral component bends. There are potential disadvantages to this type of prosthesis.

Disadvantages: When sitting down the patient will have to take the weight off the leg to allow it to bend, this means that they will not be able to use the prosthetic side in the sitting motion. The patient will also need to take the weight off the leg before the knee will bend, this means that the normal knee flexion at toe off will not happen.

Prostheses are artificial parts that replace a missing part of the body. A prosthesis is designed to improve someone's quality of life by restoring a function or their appearance, and often both. Many basic prostheses are available through the public health system. What are prostheses?
