Total Knee Replacement is surgery to replace diseased or damaged joint surfaces of the knee with metal and plastic prosthetic devices.
Most knee replacements are performed to relieve severe pain from arthritis or injury in the knee that limits an individual’s ability to do the things they want to do. It might also be performed to remove tumors of the knee.
With a new joint, you'll hurt a lot less, and you may even be pain-free. Depending on your age, you may be able to use your joint normally and move it around with a full range of motion. This should make everyday tasks like walking and household chores much easier. In some cases, you may be able to start playing sports -- low-impact stuff like golf or cycling -- that were impossible before your surgery.
The procedure can cause complications, such as infections and blood clots. Infection. If bacteria end up inside your body in a place they're not supposed to be, they can cause an infection. Any type of surgery raises your chances of this problem, and that's true of joint replacement procedures. About 1 out of 100 people who have a joint replaced get an infection after the surgery. It can show up right after the procedure or months or years later. And if you're obese or have diabetes, you may have greater odds of getting an infection after joint replacement.
Surgery may be performed under a general or spinal anesthesia. During the procedure the surgeon shaves the joint cartilage at the ends of the femur and tibia (sometimes the cartilage of knee cap) and fits them with prosthetic caps. These are then re-attached to the remaining bone with specialized cement. You will return from surgery with a large dressing on the knee. A drainage tube will be in place to help drain excess fluids from the joint in the days following surgery. You will be required to wear pressure stockings immediately after surgery to prevent blood clotting.
Before proceeding with surgery, patients will get to learn about the procedure step-by-step — before, during, and after surgery. They will learn the roles of the physician and anesthesiologist, as well as the roles of the physical rehabilitation team such as muscle strength training and helping the patient learn how to walk with their new joint. If you use cigarettes or other tobacco products, stop or cut down. Smoking slows your recovery and makes your wounds take longer to heal. It also raises your chances of complications and infection during and after the surgery.
In most cases, with pain medication administered both before and after surgery, patients are able to stand and walk the day after surgery and return home 3-5 days later.
There are possible risks and complications associated with anesthesia, including respiratory or cardiac malfunction. Other complications include the possibility of: Infection requiring antibiotics and in some cases hospitalization Infection occurring around the joint years after the surgery Blood clots in the legs (deep vein thrombosis), which can dislodge and move to the lungs (pulmonary embolism) Injury to nerves or blood vessels Loosening or dislocation of the prosthetic devices Joint stiffness Risks can be reduced by following the surgeon's instructions before and after surgery.
Who is a suitable candidate for the procedure?
Candidates for total knee replacement should be free of infection. You will receive an extensive pre-operative evaluation to determine if you are a good candidate for the total knee replacement procedure. The surgeon will make the final determination of each patient’s eligibility for the procedure after an examination and consultation with the patient. Post operative progress is determined largely by patient effort.
