Things to Know about a Total Knee Replacement Surgery

Knee joint is known to be the highest weight bearing joint in the human body. Hence, good knees are an essential part of a healthy lifestyle. However, when injury or arthritis occurs then the ability of a person to carry out daily chores is impaired. And if no chance of physical exercises and medications can help, then the requirement of Knee Replacement surgery occurs.

So, what is Knee Replacement surgery?

Knee replacement surgery involves replacing damaged cartilage (cushion) and bone in your knee hinge joint with an artificial joint or implant made of metal or ceramic or plastic to enable the joint to move in the same way like a natural joint.

You may either require a Partial or Total Knee Replacement surgery cost depending on how damaged your knee is. However, 90% of the patients go for Total Knee Replacement surgery.

And, what does the surgical procedure involves?

Total knee replacement surgery is generally performed under general anaesthetic. Procedure involves moving your patella (kneecap), in order to access your knee joint. The damaged ends or the surface of the bone are removed with the help of specially designed instruments and replaced by implant which have been precisely measured to fit aptly. The implant is held into place by press – fitting method or by special cement.

There are several varieties of implants available, and your surgeon can guide you depending on several parameters like age, weight & strength, among others.

For 90% of the patients undergoing Total Knee Replacement surgery, the new joint lasts for 15 – 20 years.

Whilst every surgical procedure comes with risks, knee replacement surgery is no exception. Although they are rare but they can be reduced, and this include –

  • Blood clot in the knee joint leading to stroke or death
  • Pain due to strain
  • Infection of the wound
  • Implant loosening or misfits

Although all these risks can be easily wished away by talking to medical experts of online health care startups and can get help to negotiate & book surgery packages online.

Besides, there are several different types of surgical approaches for Knee Replacement based upon the incisions, like:

Total knee replacement surgery approach can be either Traditional by making 12 inches incision or Minimally Invasive Surgery by making 3-4 inches incision, or newly invented Computer Assisted Surgery.

The traditional surgical approach involves cutting into the quadriceps tendon to turn the kneecap over and expose the arthritic joint. This approach typically requires three to five recovery days in the hospital and about 12 weeks of recovery time in total. Whereas, minimally invasive surgical procedure reduces trauma to tissues, lessens pain and reduces blood clots thus helping in speedy recovery. A major difference between this approach and the traditional approach is that the kneecap is pushed to the side rather than being turned over. This leads to a smaller cut into the quadriceps tendon and less trauma to the quadriceps muscle. Since, the surgeon cuts less muscle, healing occurs faster and you are soon likely to experience better range of motion after recovery.

Recently, Computer Assisted Surgery has piqued surgeon’s interest and increasingly surgeons are turning towards it. The computer helps align the implant precisely on the bone and increases the chances that implant will work effectively. A precise fit can reduce tear and increase the artificial joint or implants life considerably.
