Knee Replacement Surgery

Total knee replacement, also known as total knee arthroplasty (TKA), is a surgical procedure to relieve severe pain and restore function in people with knee problems. This surgery is particularly beneficial for individuals suffering from significant knee pain and limited mobility due to conditions like osteoarthritis.

Understanding Knee Osteoarthritis

Knee osteoarthritis is a condition where the cartilage in the knee joint wears away over time. This can cause chronic knee pain, swelling, and difficulty moving the knee. When other treatments don’t work, total knee replacement surgery can be a great solution.

What is Total Knee Replacement?

In total knee replacement surgery, the damaged parts of the knee are removed and replaced with artificial parts. This helps reduce pain and improve the function of the knee. It’s often recommended for people with severe knee arthritis or knee injuries that haven’t improved with other treatments.

  • People with severe, ongoing knee pain
  • Those with significant knee stiffness and trouble moving
  • Individuals who haven’t improved with medications or physical therapy
  • People with knee damage visible on X-rays
