Knee Replacement

What is Knee Joint Replacement?

This is also called Total knee Arthroplasty, which is an option when the knee joint pain deters performing the daily activities and other treatments don’t bring relief.

Usually in a Knee Replacement surgery, the doctor removes the damaged bone and cartilage of the knee joint and replaces them with parts constructed from metal, hard plastic or polymers. This prosthesis will help reduce pain and improve functionality.

When is it needed?

The knee problems that bring about the need for knee replacement surgery are:

  • Osteoarthritis: wear and tear leads to softening and wearing away of the cartilage that cushions the knee bones.
  • Rheumatoid Arthritis: the synovial membrane surrounding the joint inflames and thickens, damaging the cartilage causing cartilage loss, pain and stiffness.
  • Post-Traumatic Arthritis: This follows a serious knee injury where the bones surrounding the knee fractures or torn knee ligaments might damage the articular cartilage over time. Knee pain and limited knee function ensues.
