Uncemented surface replacement of the knee joint.

A method of surface replacement of the knee joint using an uncemented titanium-on-high-density-polyethylene prosthesis has been investigated in 61 patients. The results show that pain is relieved in the vast majority of cases. Overall, the joint range is marginally improved. Preoperative deformities can be considerably correced. The procedure appears to give a functional result that is comparable with other types of replacement arthroplasty and leaves complete freedom for revisional surgery at a later date should it become necessary.
