Knee Replacement Surgery Cost, Procedure, and Recovery Time

Knee Replacement Surgery Cost, Procedure, and Recovery Time

Knee replacement surgery is a surgical procedure that replaces the knee joint with an artificial one. Knee replacement surgery is usually required for a knee damaged by arthritis or severe knee-joint injury. The surgery helps overcome pain and other problems caused due to restricted movement. 

What can knee replacement surgery treat?

Given below are some of the conditions that a knee replacement can treat:


Osteoarthritis, also known as age related or wear-and-tear arthritis, is the most prevalent arthritis in the knees. It makes bones thick and roughens the joints’ surface. Due to this, the knee gets painful and stiff, and its movement is restricted. Osteoarthritis, if left untreated, gets worse with time.

Rheumatoid arthritis 

Rheumatoid arthritis, also referred to as inflammatory arthritis, is an autoimmune disease. The synovial membrane that envelopes the knee joint starts to swell in this condition. The symptoms of rheumatoid arthritis in the knee include:

  • severe pain and stiffness in the knee
  • Warmth around the joint
  • Weakness and instability in the joints when you put weight on it
  • Difficulty in straightening the knee

Post-traumatic arthritis

Post-traumatic arthritis is often characterized by damage to the knee’s cartilage due to a traumatic injury. Its symptoms are generally the same as Osteoarthritis. 

What are the types of Knee Replacement?

There are two types of replacement surgeries, namely:

Total replacement surgery

In total knee replacement surgery, all the weight-bearing surfaces of the upper and lower bones of the knee joint are taken out and then replaced with prosthetics that mimic the original knee joint functions.

Partial replacement surgery

Partial knee replacement replaces only the damaged inner (medial) weight-bearing surfaces of the upper and lower bones of the knee joint with a customized prosthesis that enables smooth joint movement. 

What is the procedure for knee replacement surgery?

The steps of a knee replacement procedure are described below:

Step 1: Making the Incision 

A 6-8 inch long incision is made at the knee joint site, and the muscles and ligaments are separated. It is done to gain access to the patella or the kneecap.

Step 2: Rotating the patella 

Once the surgeon gains access to an open knee, they rotate the kneecap to better observe the target area. 

Step 3: Preparing the femur

The surgeon resurfaces the femur, also called the thighbone. Then, after taking careful measurements of the damaged bones and cartilage, they are taken out of the site.

Step 4: Implanting the femoral component 

The doctor then attaches the femoral metal component to the end of the thighbone. To seal it into the place, bone cement is used.

Step 5: Preparing the tibia (shinbone) 

In order to resurface the tibia, the cartilage, and damaged bone are removed from the top of the tibia. Then the bone is shaped so that the metal and plastic tibial components can be fixed properly.

Step 6: Placing the tibial component 

Then using bone cement, the tibial tray is attached to the tibia and secured into place. Then the surgeon fixes a plastic spacer on the metal tray of the tibial component.

Step 7: Placing the patellar component

Prior to readjusting the patella to its normal position, the surgeon flattens and fits the patella using an additional plastic component.

Step 8: Closing the incision

Extra worn-out surfaces of the knees are trimmed off using specialized instruments. Finally, the surgeon closes the incision.

What are the benefits of knee replacement surgery?

The advantages of a knee replacement are listed below:

  • Pain relief
  • Increased strength of leg 
  • Improved mobility of knee joint
  • Corrected deformity that helps in straightening of the leg
  • Improved quality of life

What is the recovery time of knee replacement?

The recovery time of knee replacement is the time it takes to heal and regain full functionality after surgery. With the recent minimally invasive computer navigated technique pt is able to stand and walk few hours after the surgery.It is observed that patients typically return to their daily activities within six weeks, but it takes up to 8-12 weeks to perform physically demanding tasks. The recovery time for a knee replacement varies depending on the following factors:

  • Type of surgery. 
  • Age of the patient
  • Health condition
  • Bodyweight
  • Activity level

How much does Knee Replacement Surgery cost in India?

The average Knee replacement surgery cost in India lies somewhere between Rs.1,50,000 to Rs.2,00,000 for one knee which is quite low compared to western countries. The Knee replacement surgery cost varies for every individual depending on the following factors:

  • The severity of the condition
  • Type of the implant used
  • Length of the surgery
  • Location of the clinic
