Physicians work with specific health care professionals following surgery. They have protocols in place for formal physical therapy and post therapy reconditioning. Results from joint replacements are getting better all the time and so being active is common. You should ask your doctor what phase of recovery you are in and what exercise limitations as well as recommendations he has for you in particular.
