The knee is a modified hinge joint. Normally, the cartilage coating over the bones makes the joint move smoothly and provides an additional shock-absorbent cushion. Arthritis occurs when the cartilage surface wears out and you begin rubbing bone on bone. This can cause pain, decreased motion, and stiffness to the knee joint.

Non-surgical options are always considered first. These include anti-inflammatory medications, lifestyle changes, and injections. As osteoarthritis worsens, the non-surgical treatments often become ineffective. This is when knee replacement surgery, also called knee arthroplasty, is the necessary step.

Knee replacement surgery can help alleviate knee pain and allow you to live a fuller, more active life. If you and your orthopedic surgeon have determined that you are a good candidate for a knee replacement, then you are in good company. Knee replacement surgery is one of the most common orthopedic procedures performed today.

In a total knee replacement surgery, the arthritic surfaces of the knee joint are removed and new articular surfaces are provided with metal and plastic components. This relieves knee pain and allows the joint to move smoothly again.
