Cause of knee joint replacement surgery

The most common cause of chronic knee pain and knee replacement is arthritis or joint swelling. Different types of arthritis include:
  • Joint Osteoarthritis: Osteoarthritis is a type of age-related arthritis that usually occurs in people over the age of 50, but may also occur in younger people. In osteoarthritis of the joints, the cartilage gradually disappears and the cartilaginous bones rub against each other, causing stiffness and severe pain in the knee.
  • Rheumatoid arthritis: In this type of arthritis, the membrane around the joint becomes inflamed and thick, causing joint loss, pain and stiffness.
  • Post-traumatic arthritis: This type of arthritis is caused by severe knee injuries.
