Knee is the largest joint in the body that functions as a hinge between the femur, tibia and fibula. Osteoarthritis, trauma, Rheumatoid Arthritis or wear and tear can cause the joint to swell and lead to knee pain. Total knee replacement surgery, also known as Knee Arthroplasty, is a surgical procedure to correct knee joint deformity and relieve pain. Total knee replacement surgery helps in restoring the function of the joint.

When Is Total Knee Replacement Recommended?

The orthopedic surgeon may recommend total knee replacement if the patient is suffering from severe Arthritis, knee pain, bowing in or out of the knee and stiffness that restricts movement.  Patients with severe degeneration of the knee joint along with pain and restricted motion are usually recommended the procedure.

Preparing for the Surgery

Before undergoing the surgery, it is recommended that the patient discuss all queries with the orthopedic surgeon. This will assist in preparing for procedure and being aware of the required post-surgical care. The doctor may also advise refraining from certain activities and medications prior to the procedure.

Procedure

Total knee replacement surgery involves replacing parts of the knee joint with artificial components known as prosthesis. The procedure is performed under the effect of anesthesia and may take around 2 to 3 hours. The procedure generally involves four steps:

  • Prepare the surface: During this step, the surgeon removes the damaged cartilage.
  • Recreate the surface with metal implants: The damaged cartilage and bone is replaced with metal implants to create the new surface of the joint. These metal components are either cemented or pressed to fit into the bone. 
  • Resurface the patella: The surgeon removes the undersurface of the patella (kneecap) and resurfaces it with a plastic button. 
  • Create gliding surface: In this step, the surgeon inserts plastic spacer to form a smooth gliding surface.

Benefits of Total Knee Replacement

  • Substantial relief from pain
  • Ability to walk without limping or using a cane
  • It also relieves stiffness in the joint
  • The patient can find it easier to perform daily tasks, bend and climb stairs

However, in order to recover quickly and avoid complications, you must follow the instructions of the orthopedic surgeon. Post-surgical rest and exercises are crucial to ensure quick recovery. You should also visit the orthopedic surgeon periodically for checkup.
