Knee replacement, also called knee arthroplasty, is a surgical procedure to resurface a knee. The knee procedure involves shaving a small thickness of damaged bone surface and cartilage from your thigh bone, shinbone and kneecap and replacing it with an artificial surface (prosthesis) made of metal alloys, & highly durable polyethylene.
You will undergo different tests beforehand to ensure you are healthy enough for the procedure. These will include:
Our team will provide you with a complete set of instructions about preparing yourself for surgery. These can include:
You first change into the hospital gown. Our nurse inserts an IV line for injecting medication and fluids through your vein.
You will be given an intravenous antibiotic before, during, and after the procedure to help prevent post-surgical infection.
You might also be given a nerve block around your knee to numb it. The numbness wears off gradually after the procedure.
You may be put under general anesthesia, which means you will not be conscious before and during the surgery or under spinal anesthesia, which leaves you awake but unable to feel pain from your waist down.
Your knee will be in a bent position to expose all surfaces of the joint. After making an incision about 6 to 10 inches long, your surgeon moves aside your kneecap and shaves the damaged joint surfaces.
After preparing the joint surfaces, the surgeon attaches the pieces of the artificial joint. Before closing the incision, he or she bends and rotates your knee, testing it to ensure proper function. The surgery lasts about one to two hours.
There are four basic steps to a knee replacement procedure.
You are brought to the recovery room until you recover from anesthesia, and your vital signs are closely monitored the entire time.
You will be encouraged to move your foot and ankle, which increases blood flow to your leg muscles and helps prevent swelling and blood clots.
You will likely receive blood thinners and wear support hose or compression boots to further protect against swelling and clotting.
You will be asked to do frequent breathing exercises and gradually increase your activity level.
The day after surgery, a physical therapist will show you how to exercise your new knee. After you leave the hospital, you will continue physical therapy at home or a center.
The report of the procedure, discharge medications and follow up appointment details will be provided to you at the time of discharge.
Do your exercises regularly, For the best recovery, follow all your care team’s instructions concerning wound care, diet and exercise.
