The knee will not bend as far as it did before you developed knee problems, but the surgery
will allow you to stand and walk for longer periods without pain
. After surgery
, you may be allowed to resume activities such as golfing, riding a bike, swimming, walking for exercise, dancing etc. Keeping in view the restriction on bending the knees, you may not extremely bend the knee but may learn to discover a new position on the top but with less bending of affected knee. That will help.
