Prosthetic Implant

The design and size of the prosthetic implant are usually chosen to fit the patient’s needs, whereas the material of the implant is usually made of titanium or cobalt-chromium.

The spacer inserted between the implanted surfaces of the shinbone and the femur is made of polyethylene (plastic). The spacer is used as a shock-absorber, and it allows full range of motion. The prosthetic parts are fixated in place by using cement or osseointegration (direct attachment between the bone and the implant).
