Joint Replacement
Knee Replacement Surgery
An arthritic joint is prepared by removing worn and damaged joint surfaces, and replacing or resurfacing the joint surfaces with a metal and plastic artificial joint.
Following your anesthetic, the surgeon will trim the damaged parts of the femur, tibia, and kneecap. Bone cuts are made with precision so that proper leg alignment and balance of the knee ligaments is maintained. A metal thigh bone component, a plastic kneecap, and a metal and plastic leg bone component are cemented into place. Components are selected that are appropriate for your size, and correct thickness to properly tension the knee ligaments.

Periodic media reports and attorney solicitation advertisements raise concerns regarding “recalls” of artificial joint systems. The majority of artificial joint “recalls” in the past ten years have involved newer prosthetic designs. These are systems that have only a short track record of durability or survivorship studies. The Sonora orthopedic surgeons select artificial joint systems that have a long track record of success and durability. Please feel free to discuss this with your surgeon.
