KNEE REPLACEMENT SURGERY

Overview

Knee replacement surgery, also known as knee arthroplasty, replaces a diseased knee joint with an artificial knee joint or an implant. It helps relieve pain and restore functions in the knee affected with arthritis. Dr. Abhijit Kale is the best knee replacement surgeon in Mumbai and given below are the insights into his advanced knee replacement surgery.

What can knee replacement surgery treat?

Given below are the conditions that the surgery can treat according to a knee pain specialist in Mumbai:

Osteoarthritis
Osteoarthritis is the most prevalent form of arthritis in the knee. It is a degenerative disease that results due to wear and tear of the cartilage in the joints. Due to this, bones become thick, the joints’ surface becomes rougher, and the knee movement is restricted.

Rheumatoid arthritis
In rheumatoid arthritis, the synovial membrane that envelopes the knee joint starts to swell. It is an autoimmune disease, and also known as inflammatory arthritis, as it causes severe pain and stiffness in the knee.

Post-traumatic arthritis
The symptoms of post-traumatic arthritis are generally the same as Osteoarthritis. It is characterized by damage to the knee’s cartilage that takes place due to a traumatic injury.

Who is and isn't a candidate for knee replacement surgery?

Given below are the symptoms of a patient who is a candidate for knee replacement surgery:

  • Severe and continuous knee pain
  • Knee stiffness that restricts daily activities such as walking and even getting up
  • Chronic knee inflammation and swelling
  • Knee deformities such as bowleg or knock knees

 

However, some people can’t undergo knee replacement surgery no matter how severely their knees are diseased. So the people who are not suitable for the surgery according to a Knee pain specialist in Mumbai are those:

  • who have very weak thigh muscles and won’t be able to support the new knee joint, and
  • Ulcers in the skin below their knee because it increases the risk of infection.

What are the types of knee replacement surgery?

Total Knee Replacement (TKR)
The total knee replacement surgeries involve replacing the joint surface at the end of the thigh bone and the joint surface at the top of the shin bone. A TKR may also involve replacing the under-surface of the kneecap by using a smooth plastic dome.

Partial Knee Replacement
Partial or unicompartmental knee replacement is performed if arthritis affects only one side of the knee. Compared to a total knee replacement, it involves less meddling with the knee, so it takes a lesser recovery time and gives better function.

Kneecap Replacement
A kneecap replacement, also known as patellofemoral arthroplasty, is performed when the under-surface of the kneecap and its groove are affected by arthritis. It is one of the toughest operations and gives better results when arthritis doesn’t progress.

Revision/complex knee replacement
As suggested by the name, a revision knee replacement surgery is performed if a patient has a second or third joint replacement in the same knee. This kind of surgery is performed when a patient suffers bone loss or deformity in the knee due to severe arthritis or some fracture.

How is knee replacement surgery performed?

A knee replacement surgery is performed either under general, spinal, or epidural anesthetic. The step by step procedure for a total knee replacement surgery is given below:

Step 1: Making the Incision
The surgeon makes a minimal incision to gain access to the patella or the kneecap. The length of the incision is near four to six inches.

Step 2: Rotating the patella
Once the knee is open, the surgeon rotates the patella outside the knee area. By doing this, they get a better view of the area under treatment.

Step 3: Preparing the femur
The surgeon resurfaces the femur or the thighbone. Measurements of the damaged bones and cartilage are carefully taken, and then it is cut away.

Step 4: Implanting the femoral component
The surgeon attaches the femoral metal component to the end of the femur and uses bone cement to seal it into place.

Step 5: Preparing the tibia (shinbone)
The surgeon resurfaces the tibia now. The cartilage and damaged bone are removed from the top of the tibia and then shape the bone to fix the metal and plastic tibial components.

Step 6: Placing the tibial component
The tibial tray is attached to the tibia and secured into place using bone cement. A plastic spacer is then fixed on the metal tray of the tibial component.

Step 7: Placing the patellar component
Before returning the patella to its normal position, the surgeon flattens and fits the patella using an additional plastic component.

Step 8: Closing the incision
Finally, the surgeon closes the incision using nylon stitches.

What are the benefits of knee replacement surgery?

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