What can be expected after having a total knee replacement?

Pain...and work! Assuming the knee was placed correctly, now it is up to you and the other health care providers to assure the best chance of you being satisfied with the results. You and your md are a team... As is your pt. You need to religiously perform your stretching exercises, attend your pt sessions and let your doc know of any issues quickly since the first few months are critical.
Physical Therapy. Physical therapy is important after a total knee replacement. Once you are able to bend your knee more than 110 degrees the recovery becomes easier.
