Knee replacement is a procedure that involves the replacement of a knee. Also called knee arthroplasty, this procedure is often done to treat joint pain. Usually, the pain and stiffness of the knee are too much to the point that the individual is no longer able to move or perform even the simplest tasks and activities considering that no treatment is working. Generally, knee replacement is reserved for people age over 50 who are suffering from severe osteoarthritis.

There are other conditions that may need knee replacement surgery. An example can be when there is severe arthritis or injury to the knees that prevents an individual to perform simple activities, such as walking, moving from one place to other, climbing stair and so on. Pain may increase even when sitting or lying down.
When other treatments such as medications, using walking supports or topical applications are no longer working, total knee replacement may be the best choice.

How the Knees Works

The knee is the largest joint in the body and in order to perform all activities within the day, we need a healthy knee to be able to do that. The knee is made up of the patella or kneecap, the lower end of the thighbone or femur and the upper end of the shinbone or tibia. A smooth substance protects the bones and allows them to move easily, it is called an articular cartilage. It also covers and protects the ends of the three bones.

There are C-shaped wedges that act as shock absorbers and cushion the joints during movement. These wedges are called the menisci located between the femur and tibia. In order to have stability, the femur and the tibia are held together by large ligaments. Long-thigh muscles give strength to the knees.
A special connective tissue called a synovium produces synovial fluid to lubricate the joints to prevent friction.
All of these components work in harmony for maximum functionality of the knees. However, accidents, injuries and diseases can occur and these conditions can affect the knees causing pain and muscle weakness.
