The main goal of rehab is to allow you to bend your knee at least 90 degrees-enough to do daily activities, such as walking, climbing stairs, sitting in and getting up from chairs, and getting in and out of a car. Most people can get considerably more bending than 90 degrees after surgery. Thu, 16 Feb 2012 06:03:19 UTC en
