 Hello, I am Dr. Sunil Kini, consultant joint replacement and arthroscopy surgeon at Manipal Hospital's Bangalore. So after knee replacement, there are two things which can persist for a considerable amount of time. Firstly is the swelling and secondly is the pain. It's prudent to explain to the patients that the decline in the pain starts immediately after surgery and can continue for up to three months. Similarly for the swelling, it is normal to have a swelling for up to six months or in certain patients up to a year after surgery. There are some ways in which we can decrease the swelling. First and foremost of that is the icing. So once you ice, considerably the swelling goes down over a period of time. The other question is to use compression stockings or not. Initially there are some surgeons who used to use compression stockings in all patients. But as a generalized term, we assess the patients for risk of what is called as a deep pain thrombosis or DVT. So if patient is at a risk of DVT or if the patient has not walked for a considerable distance at the time of discharge, it's always better to use compression stockings. So compression stockings can be either worn below the knee or above the knee. The advantage of using compression stockings is to decrease the swelling and also decrease the chance of what is called as deep pain thrombosis. But it's actually icing rather than heating which should be used for post-totally replacement which is often used to actually decrease the swelling.
