Total knee replacement is also called total knee arthroplasty. It is surgery that is done to remove and replace (or resurface) the worn parts of your knee joint. The knee is made up of the lower end of the thighbone (femur), the upper end of the shin bone (tibia), and the kneecap (patella), which slides in a groove on the end of the femur. Large ligaments attach to the femur and tibia to provide stability. The long thigh muscles give the knee strength. The joint surfaces where these three bones touch are covered with articular cartilage, which cushions the bones and enables them to move easily. A thin membrane releases a special fluid that lubricates the knee, reducing friction during movement.
Normally, all of these components work in harmony. However, disease or injury can cause pain, muscle weakness, and reduced function. If you have these problems, you may need to have a total knee replacement. During the total knee replacement, the damaged surfaces of your knee joint are removed and replaced with an implant. This implant may be made of metal and/or plastic. Total knee replacement surgery may decrease or take away your knee pain and make standing, sitting, and walking easier.
