Total Knee Replacement

Total knee replacement surgery is one of the most successful procedures performed worldwide. It involves replacement of the diseased or damaged knee joint with an artificial material called prosthesis.

Indications for Total knee replacement

  • Chronic knee pain, stiffness and disability

  • Osteoarthritis

  • Rheumatoid arthritis

  • Severely damaged knee due to an injury

  • Torn knee ligaments that may damage the articular cartilage over time

  • Failed nonsurgical treatments like medications, physical therapy and walking supports

The procedure is performed by an orthopaedic surgeon under general or regional anaesthesia. It involves removal of the end of femur bone and its replacement with a metal shell. The end of bone of lower leg i.e. tibia is removed and replaced with a channeled plastic piece with a metal stem. In addition to the replacement of parts of bones of upper and lower leg, depending on the condition of the kneecap portion of the knee joint, a plastic “button” may also be added under the kneecap surface. The posterior cruciate ligament is either retained, sacrificed, or substituted by a polyethylene post.

The procedure itself takes approximately 1 to 2 hours.

Single and Bilateral Joint Total knee replacement

Total knee replacement surgery can be performed on single or both knee joints depending upon the damage of the joints and patients age and overall health. The procedure for single joint replacement remains same while bilateral can be performed in following ways:

  • Simultaneous bilateral knee replacement is one surgery for both joints in single sitting under one anesthesia

Benefits of Simultaneous Bilateral Total knee replacement

  • Low cost: The cost of bilateral replacement is approximately 20% cheaper when compared to combining two separate single total knee replacement surgeries.

  • Reduced length of hospital stay: Patient needs to stay less in hospital stay by approximately 7 days when a single procedure is performed for both knees.

  • Avoids readmission in the hospital for second knee replacement surgery

  • Reduced exposure to anesthetic medications and associated complications.

  • Simultaneous rehabilitation of both the knees can be done at the same time.

  • Quicker recovery

  • Avoids the need of heel raise in slippers of non-operated side limb for limb length discrepancy

Benefits of Total knee replacement

  • Safe and effective procedure to relieve pain & stiffness of knee joint

  • Increase mobility

  • Corrects leg deformity

  • Helps to resume normal daily activities

  • Restores the alignment and function of knee

  • Improves quality of life because everyday activities and exercise become easier

Prognosis of Total knee replacement

Although most of the patients experience remarkable decrease in the pain and increased mobility of the knee joint, but still some risks and complications may occur after total knee replacement. To have an improved quality of life after surgery, patient should religiously follow the instructions and perform rehabilitation exercises as advised by the surgeon and physical therapist. In case of any unusual symptoms, patient should immediately report to their physician.
