Knee replacement surgery involves the replacement of a kneecap. In this procedure, the surgeon cuts away the damaged surfaces of the knee and attaches the artificial joint pieces. He then tests the replacement to ensure it functions. The surgery is generally over within two hours. After the surgery, patients are encouraged to engage in physical therapy. This rehabilitation may be painful, but it is necessary to keep the knee strong and active to avoid complications. Depending on the type of surgery, physical therapy may be performed at home or in the hospital.
Risks associated with Knee Replacement surgery include a decrease in the range of motion, numbness, and reduced function of the joint. While fewer than 1 in 100 patients suffer nerve damage, it may require a subsequent surgery. Surgical procedures can also damage blood vessels or nerves surrounding the joint, which may require further treatment or surgery. Another risk is decreased blood flow to the muscles surrounding the new joint, known as compartment syndrome.
Patients undergoing knee replacement surgery will be put under sedation during the procedure. A local anaesthetic is injected into the knee tissues during the operation to numb the pain and allow the muscles to work. This also allows patients to get up faster after surgery. After surgery, they should follow a prescribed schedule of physical therapy to help them recover. Visit QC Kinetix (Aurora)-Aurora Back Pain Treatment for more details.
During the procedure, the worn-out ends of bones and hard cartilage are removed. Then, plastic or metal parts replace these parts. Plastic acts like hard cartilage and makes the knee joint more stable. The artificial joint also features interlocking parts that allow the knee to bend and stabilize. A knee replacement may be necessary for patients with advanced arthritis or other problems related to the knee.
After knee replacement surgery, patients are usually discharged after four to six weeks. Physical therapy is important for strengthening the knee. Patients should avoid extreme sports for several weeks after surgery. The recovery time after surgery varies from person to person. Some people may have minor discomfort, while others experience severe pain and difficulty moving their knee.
Depending on the type of surgery, patients may need to stay overnight in the hospital. They will likely be on pain medication for a few weeks, but the pain will eventually subside. After surgery, patients should start physical therapy to strengthen their muscles and avoid circulation problems. This can take up to six weeks, but it is important to keep in mind that pain relief is not a guarantee of recovery.
The most common reason for knee replacement surgery is knee osteoarthritis. It may also be a result of other types of arthritis or a poorly formed joint. In either case, surgery will replace the damaged cartilage and bones in the knee. The procedure will also restore mobility.
