Before starting the anaesthesia, an intravenous line in the forearm will be taken to administer various medications. As discussed previously you will be administered the anaesthesia most suitable for you. If it is going to be epidural anaesthesia, you will be made to sit and your lower back will the cleansed with an antiseptic solution. Then after numbing your skin, a thin tube will be inserted in your back with the help of a special needle.

The actual surgery consists of entering the knee joint through an incision in front of the knee. The irregular cartilage of at the ends the thighbone, leg bone and the kneecap will be shaved by a power saw to the extent of 8-10 mm and the artificial parts will be fitted on the shaved bones with the help of substance called bone cement. During the surgery, the tension in the knee ligament will be adjusted so that the deformity present before the surgery will disappear completely. At the end of the surgery, the knee will be thoroughly washed with antiseptic solution and a thin plastic tube will be inserted in the joint to drain out the blood, which is likely to ooze during first 48 hours. After meticulously stitching up of the wound, a bulky compression dressing will be applied.
