- Osteoarthritis is the most common cause for a knee joint to be replaced. Osteoarthritis of the knee results in gradual deterioration of cartilage, which causes pain and reduces joint function.
- Certain types of knee injuries, including fractures and major cartilage tears, can damage the joint beyond repair and necessitate the need for replacement surgery.
- Rheumatoid arthritis, which is an autoimmune disorder, can attack the knees and, in severe cases, cause significant joint deformity and pain, resulting in the need for replacement surgery.
- A degenerative condition that causes a lack of blood flow to a portion of bone, avascular necrosis can affect the bones that form the knee joint and cause deformity, pain, and stiffness. Severe cases can destroy the joint and require total knee joint replacement to correct.
- A type of knee arthritis that develops as the result of injuries, traumatic arthritis can severely damage the joint and necessitate the need for total knee replacement surgery.
