Knee replacement

What is knee replacement surgery?

Due to knee pain, many people find it difficult and painful to do daily activities such as walking, sitting, and climbing the stairs. Knee replacement(Arthroplasty) is a procedure done to relieve pain and problems associated with the knee due to arthritis by the procedure of ‘resurfacing’. This procedure is mainly used when pain associated with the knee cannot be relieved from other medicines and treatments

How knee replacement surgery is performed?

There are four steps:

1. The diseased cartilage surface along with some amount of underlying bone at the ends of the femur and tibia are removed.

2. It is then replaced with metal components that recreate the surface of the joint. 

3. The undersurface of the kneecap (patella) is cut and resurfaced.

4. Then a medical-grade plastic spacer is inserted between the metal components to provide a smooth gliding surface. 

Procedure Associated with the surgery

During the surgery, your knee will be kept in a bend position exposing the surface of the knee clearly. Then an opening of about 6-10 cm is made and the surgeon removes the damaged surfaces of the joint. 

After the removal, the surgeon attaches the artificial joint to the end of the thigh and calf bones. The artificial joint is usually made up of metal. For smooth movement, a plastic spacer is used between the metal parts.

A knee replacement surgery usually takes about 1 to 2 hours and sometimes this time can vary depending on the complexities associated with the surgery performed.

Why do you need knee replacement surgery?

Osteoarthritis, rheumatoid arthritis, disorders that cause unusual bone growth, osteonecrosis, knee injury, knee deformity with pain and loss of cartilage. If the above conditions don't improve with other treatments such as anti-inflammatory medications, cortisone injections, lubricating injections, physical therapy, or other surgeries, then knee replacement surgery will be recommended.

Preparation for recovery

For several weeks after the procedure, it will be difficult for you to walk or move. You will need the help of crutches or a walker. You should need the help of a person to do your cooking, bathing, cleaning and other basic needs.

Since climbing the stairs will be difficult after the surgery, you should create a living space in the floor without getting there by stairs. While bathing, you should arrange a chair as standing there can affect your knee. Make sure to install proper bars to support your movement wherever necessary.
