The knee is the largest joint in the body so it follows that partial or full knee replacement is considered a major surgical intervention that puts major strain on your body. It is normal to feel exhausted afterward and the effects of anesthesia, the initial pain and discomfort should not be disregarded. You should give yourself plenty of time to rest after a knee replacement operation.
Depending upon your physical condition, you may be given a temporary brace to help bolster weak ligaments or improve wound healing and you may have foam wedges or pillows under and around your new joint to help immobilize it.
You will want to rest after surgery, but it is also important to get moving quickly to help counteract the effects of anesthesia, promote mobility and start the healing process. Your doctor and care team will determine when you can begin getting up and moving around. Crutches or a walker may be prescribed initially depending upon your diagnosis and surgical intervention.
Your doctor and a physical therapist will give you specific instructions on wound care, pain control, diet, and exercise. They will also advise you on any other knee injury treatment.
