Knee replacement surgery is a complex procedure that can take anywhere from 45 minutes to two hours. After the surgery, most people will stay in the hospital for one to four days. During this time, they should follow their doctor’s instructions, such as taking crutches or walking with a frame. They will also be given exercises to strengthen their knee. It may take up to six weeks to be able to stop using crutches or a frame.
The procedure involves cutting the femur and tibia and removing both the cartilage and bone. The cartilage and bone are then replaced with a metal component. These implants mimic the original shape of the femoral condyles and are placed in the joint. Some types of knee replacement also include polyethylene implants that replace the underside of the kneecap. Learn more about them at Aurora Knee Replacement-QC Kinetix (Aurora)
Patients are usually given sedative medication in the admission ward prior to surgery. They are also given a general anaesthetic, which will numb the entire body from the waist to the knee. The anaesthetic may also contain a nerve block, which will block pain for up to 36 hours. This may also cause temporary weakness of the leg.
The complication rate after total knee replacement surgery is low, but if you experience any signs of infection or a blood clot, you should seek medical care right away. These symptoms include fever, redness, pain, drainage, swelling, or increased pain. If the replacement becomes loose or falls out, you may need additional surgery.
Another type of knee replacement is called a partial knee replacement. This procedure is ideal for patients who only experience pain on one side of the knee, but do not have osteoarthritis. This operation preserves the rest of the knee joint. In addition, it is more predictable. However, this method has some risks, which make it difficult for patients to recover from it.
Knee replacement is one of the most common types of joint replacement surgery. The procedure replaces arthritic knee surfaces with well-engineered bearing surfaces. About 90% of patients with this surgery experience significant improvements in pain and function. Despite these benefits, knee replacement has its risks, and patients must consider all these factors before making the decision to undergo the procedure.
A knee replacement surgery, also known as a knee arthroplasty, involves the removal of the damaged cartilage and bone around the knee. A surgeon will then implant an artificial joint into the knee. This will restore the knee’s function and allow patients to walk again. Knee replacement surgery is an option for patients with severe knee damage caused by osteoarthritis, rheumatoid arthritis, or a severe injury.
