What Is Knee Replacement Surgery?

Knee Replacement Surgery

It is an operation that consists of replacing the knee joint with components made of metal and polyethylene. The lower end of the femur and the upper end of the tibia is removed. The bones’ particular parts are replaced with a metal part attached to the lower end of the femur and a plastic/metal component on the upper end of the tibia.

Also, the posterior face of the patella can be rectified. The operation relieves pain, usually caused by wear and tear on the knee joint. The process can even restore mobility to the knee.

There are two types of knee replacement surgery

 Partial Knee Replacement

A partial knee replacement is performed to restore the worn part of the knee. This operation usually takes place if only part of the knee is damaged.

 Knee Arthroplasty By Total Prosthesis

The knee is one of the largest and also most complex joints in the body. It consists of the lower end of the femur, which rotates on the upper end of the tibia, and the patella, which slides into a groove on the femoral part. Thick ligaments attached to the femur and tibia provide stability to the knee. The long thigh muscles strengthen the joint.

Also total knee replacement surgery involves replacing injured or damaged parts of the knee with artificial implants. Your new knee will consist of a metal component attached to the femoral region, a metal and also polyethylene insert on the tibial part, and, if necessary, a polyethylene patellar insert.

If you have any questions, ask your doctor or orthopedic surgeon.

The Operation

It takes about 1 to 2 hours, and also the patient’s stay in the hospital usually lasts between 3 and 10 days. The operation consists of an incision 10 to 22 centimeters long made on the top of the knee. You may have stitches or staples that resolve on their own. But if they don’t, you will need to have them removed about two weeks after the operation.

Convalescence

The length of a patient’s hospital stay after the operation depends on several factors, including social considerations. It is because people living in a single-story house, apartment, or villa where the bedrooms and bathroom are located on the ground floor will return home sooner than people who have a lot of stairs to climb. People with home help or a family member to look after them will fare better than those who live alone.

Back-to-work

Usually, recovery lasts three months, but many patients, especially those with sedentary work, can return to work much earlier. Everyone is different, and your doctor is in the best position to advise you when you are ready to return to work.
