Knee replacement surgery is an aggressive treatment option for patients whose knee joints have degenerated, causing chronic pain and immobility. Following the procedure, it is vital that you follow an exercise program to help reduce pain and promote flexibility and strength in your knee. After several months of rehabilitation, you should be able to resume your normal life without any pain in your knee.
Knee Replacement
A knee replacement is a surgical procedure in which sections of the bones in your knee are replaced with an artificial implant. Knee replacements are common treatment options if your damaged knee joint causes severe pain and immobility. Usually this is the result of chronic arthritis, which has worn down your knee. During the procedure, an incision is made over your knee. Your surgeon then cuts your thighbone and shinbone flat, and the damaged portions are removed. The implant is inserted and secure and the incision is closed.
Types of Knee Replacement
There are two different types of knee replacements: partial and total. A partial replacement, known as unicompartmental knee arthroplasty, involves replacing either the inside or outside compartment of the knee. During total replacement, the entire knee joint is replaced. Because partial replacement only involves part of the knee, it usually requires a shorter rehabilitation and recovery time, and generally results in a greater range of motion after the surgery.
Rehabilitation Exercise
Rehabilitation is a vital part of the recovery process following a knee replacement. Physical therapy will help you regain strength and range of motion in your knee and allow you to return to normal activities without any pain. Your rehab should be supervised by a physical therapist who will guide you through your program. Exercise will begin almost immediately. During the first few days, you will be encouraged to move your ankle and foot, as well as move your knee with the help of a continuous passive motion machine. This is designed to decrease swelling, improve circulation and restore function. You can then begin to walk around with the aid of a cane or crutches. Once you are physically capable, you may begin to participate in physical activity. Exercise is recommended. However, you should stick to such low-impact activities as walking, swimming and bike riding. High-impact sports, such as running and jogging, are usually prohibited as they can damage your knee.
Recovery Timeline
You will be in the hospital for a few days following surgery. Your rehabilitation will continue for several weeks or months. There are many factors that affect your recovery time including your age, overall health and type of replacement. Generally, patients should be able to gradually resume normal activities within four to six weeks. However, full recovery may take several months. Knee replacement is considered a highly effective treatment, and most patients who follow a proper physical therapy program return to daily life pain-free.
