The benefits of knee replacement surgery are far too many. Ofcourse it is a major surgery. So it has its own pros and cons. After a knee replacement surgery, several benefits are mainly pain relief. The pain relief is so much so that the patients quality of life changes dramatically. Their walking distance improves, they are able to do all their activities of daily living quite comfortably. They are able to climb stairs, as much as they want they are able to take part in sporting activities like swimming or even golfing, they are able to drive cars and play with their grand children. Ofcourse there are certain restrictions where we don’t allow or recommend not to sit on the floor or sit crossed leg or do squat because the pressure on the replaced joint surfaces is too much and if you can destroy God given bones, then knee replacement is after all a manmade substitute.
