What Is The Procedure Of Knee Replacement Surgery?

Knee replacement, also described as arthroplasty, is a surgical method to resurface a knee injured by arthritis. To surgery this painful knees doctors use metal or plastic parts to cap the edges of the bones that make the knee joint, by kneecap. This surgery may analyze for someone who has severe arthritis or a severe knee injury.

Several types of arthritis may affect the knee joint. Osteoarthritis, a degenerative joint disorder that affects mostly middle-aged and older adults, may cause the breakdown of joint cartilage and nearby bone in the knees.

Rheumatoid arthritis, which produces inflammation of the synovial membrane and results in an excessive synovial fluid, can lead to pain and stiffness. Traumatic arthritis, arthritis due to illness, may cause damage to the cartilage of the knee.

The purpose of this surgery is to resurface the parts of the knee joint that have injured and to reduce knee pain that cannot be controlled by other treatments.

A Procedure Of The Knee Replacement Surgery:

Step 1:

The surgeon cuts the front of your knee to gain access to the patella, usually referred to as the kneecap. In a regular knee replacement, the incision is often about 8 to 10 inches long. In minimally invasive knee surgery, the jury is still out as to whether or not the pros of the smaller injury outweigh the cons of a smaller surgical area. Talk to your doctor regarding which method is right for you.

Step 2:

The first portion of your knee that presented is your kneecap, called the patella. Once your knee is open, the surgeon turns the patella outside the knee area. This enables the surgeon to view the area needed to perform the surgical procedure.

Step 3:

The first bone, your doctor, will resurface is your femur, generally known as the thigh bone. Once the surgeon has cleared up and exposed your knee joint, he or she will carefully contain your bones and make precise cuts using special instruments.

The broken bone and cartilage from the end of the femur cut away. The end of your femur is cut and resurfaced to fit the first part of the affected knee, the femoral component.

Step 4:

The surgeon adds the femoral metal component to the end of your femur and uses bone cement to seal it into place.

Step 5:

The next bone, your specialist, resurfaces is your tibia or shinbone. The surgeon removes broken bone and cartilage from the head of the tibia and then prepare the shape of the knee to fit the metal and plastic tibial parts.

Step 6:

The bottom part of the implant, called the tibial tray, is implemented to the tibia and secured into place using bone cement. Once the plate is in place, the surgeon will snap in a polyethylene (medical-grade plastic) enter to occupy between the tibial tray and the femoral component and work as a kind of shield. This insertion will provide support for your body as you turn and flex your knee.

Step 7:

Before replacing the patella to its normal position, the surgeon might require to flatten the patella and fit it with an additional plastic part to ensure a proper fit with the comfort of your implant. The plastic piece, if required, is cemented to the underlying bone.

Step 8:

Your consultant will bend and flex the knee to ensure that the implant is working perfectly and that adjustment, sizing, and positioning is proper. To complete the method, the surgeon will close the cut with stitches or staples, and then bandage it and prep you for improving.

You may move from operating room with your leg in a continuous passive motion (CPM) machine that will gently bend and flex your new knee for you while you are lying down. Know the knee replacement procedure step by step to know who are going to treat early.
