Why would I need knee replacement surgery?

ANSWER

Osteoarthritis is the main reason why people go for knee replacement surgery. The condition is very common. It happens when cartilage -- the cushion between the knee and the bone joints -- breaks down.

Other reasons include:

  • Rheumatoid arthritis
  • Structural problems like bowed legs or “knock-knees”
  • Knee injuries
  • Loss of blood flow to the knee's bones (a condition called either osteonecrosis or avascular necrosis).
