Knee Replacement Surgery

Do you feel knee pain while walking, getting up from your chair, or standing up first in the morning after your sleep?

Have you tried all your medications, injections and therapies which do not seem to work?

If this is the case with you, it’s time to consider Knee Replacement Surgery, also known as knee arthroplasty!

Knee replacement in India is one of the most common orthopedic procedures done to give you better mobility and freedom from knee pain. It eases the severe arthritic pain and gives a new lease of life to your knee joints which makes your life easier and faster.

These days, knee replacements are also done with robotics. The surgery involves removal of the damaged knee and its replacement with an artificial knee joint made of metal, ceramic or plastic. The joint is artistically attached to the thigh bone, sheen, and kneecap with the help of acrylic cement.

Anatomy of Knee Joint

Who needs a knee replacement surgery?

Age-related joint complications in which the cartilage providing the cushion between the knee and the bone joints wear out, are the major causes to opt for this surgery.

In addition, grade 4 osteoarthritis and its various types which are degenerative and inflammatory in nature also lead to joint issues necessitating knee replacement surgery.

Other reasons include:

  • Rheumatoid arthritis attacking the knee
  • Deformities like knock-knee or bowed knees
  • Knee injuries leading to broken bone or torn ligaments

Types of Knee Replacement Surgery

There are two major types of knee replacement surgeries.

Total Knee Replacement

This is one of the most commonly preferred surgeries in which the surgeon replaces the surfaces of the thigh bone and the shin bone that connects to the knee. The Knee joint is totally replaced with an artificial joint.

Total Knee Replacement

Partial Knee Replacement

It is done when only one side of the knee is affected and the patient has strong knee ligaments and cartilages are in normal condition. Anterior or posterior part of the knee is replaced through surgery which requires smaller cut than what is needed in total knee replacement.

Partial Knee Replacement

Types of implants

Implants Longeiviety
Cocr 15 Years
Oxinium (Oxidized Zirconium) 20-25 years
Opulent (Titanium Nitride) 20-25 years


  • General or spinal anaesthesia is chosen based on your preferences and body time. General anaesthesia will keep you totally unconscious while spinal anesthesia will make your lower body part numb, not to let you feel any pain.
  • An intravenous antibiotic will be administered before, during and after the surgery to avoid any post-surgical infection.
  • A nerve block might also be administered around the knee to induce numbness around the knee.

During the Procedure

  • An incision of around 6-12 inches is made and the surgeon moves aside the knee cap to access the damaged knee portions. The damaged part is removed and the joint surfaces are prepared to place the artificial joint.
  • The artificial joint is attached and checked for its functioning by bending and rotating the knee.
  • The incision is closed.

After the Procedure

  • An incision of around 6-12 inches is made and the surgeon moves aside the knee cap to access the damaged knee portions. The damaged part is removed and the joint surfaces are prepared to place the artificial joint.
  • The artificial joint is attached and checked for its functioning by bending and rotating the knee.
  • The incision is closed.
