Total Knee Replacement
You will most likely be admitted to the hospital on the day of your surgery. After admission, you will be evaluated by your anesthetist. The most common types of anesthesia are general anesthesia, in which you are asleep throughout the procedure, and spinal or epidural anesthesia, in which you are awake but your legs are anesthetized. The anesthetist and Prof Jari will determine which type of anesthesia will be best for you with your input.
The procedure itself takes about one to two hours. Prof Jari will remove the damaged cartilage and bone and then position the new metal and plastic joint surfaces to restore the alignment and function of your knee.
Many different types of designs and materials are currently used in total knee replacement surgery. Nearly all of them consist of three components: the femoral component (made of a highly polished strong metal), the tibial component (made of a durable plastic often held in a metal tray), and the patellar component (also plastic). Prof Jari, and many other surgeons, does not resurface your kneecap (patella) routinely. The reason for this is that there is no clear evidence in the scientific literature to support this. So at the end of the operation, the femur and tibia will have been replaced and you will still have your own kneecap.
After surgery, you will be moved to the recovery room, where you will remain for one to two hours while your recovery from anesthesia is monitored. In the recovery room your leg will probably be put in a Continuous Passive Movement (CPM) machine, which will gently move your knee for you and elevate your leg. You may also have a Cryocuff (cold compression device) on your knee which will be put on in the operating theatre. This device helps to control your swelling as well as helping with your pain control.
