Policy context

Knee joint replacement or knee arthroplasty is surgery to replace a diseased knee joint with an artificial joint. It is an elective procedure, generally indicated for patients with significant loss of cartilage to bone, experiencing pain and limited range of motion. Questions primarily center on when the procedure is most appropriate and for whom, and whether certain types of procedures produce better results. Important questions remain about appropriate patient selection; timing; and clinical indications for knee replacement, as well as information on the use of different surgical approaches; prosthesis types and materials; and its safety and effectiveness and cost effectiveness compared to alternatives.
