Just got a new knee, but the rest of the leg/body cannot keep up? That is very common because all the other parts are not getting any younger and probably have become weak and deconditioned on account of you favoring your knee. Try a little physical therapy to give the rest of your leg and body a tune-up. Tune-up's are not just for cars, your body can benefit from some fine tuning too. With a little more strength and better ways to do things, you should be able to keep up with that new knee.
