A knee replacement surgery consists in removing the bone and cartilage of the joint damaged by arthritis and replacing these structures with highly biocompatible metallic and plastic components that form an artificial joint, or prosthesis.
A Total Knee Replacement is usually considered when osteoarthritis affects more than one compartment of the knee, in case of ligament deficiency or damage, and correction of intra-articular deformities.
In total knee replacement surgery, the entire surface of the thigh bone (femur) and shin bone (tibia) are replaced with high-resistant metallic components, called the femoral component and tibial baseplate. A strong, plastic insert is implanted between the femoral component and the tibial baseplate. This insert replaces the cartilage function, allowing the thigh and shin bone to slide on each other. The undersurface of the kneecap may also be replaced with an implant made of plastic.
With almost 50 years of history, total knee replacement surgery is a very common and safe procedure for the treatment of severe arthritis. Approximately 1,000,000 knee replacements are performed annually worldwide.
The main benefits of a successful total knee replacement are:
The pain may be rapidly and dramatically reduced, usually eliminated.
With less effort, you may regain close to the original mobility of your knee.
Your everyday activities and your social life should no longer be limited by pain and reduced mobility.
