Beth,

My wife was standing behind me while I was reading your mail and
she, being of the exercise science degree (next term), suggested 
that you do slow, controlled squats or half-squats (don't go down
to 90 degree bend) so that you build up the muscles surrounding the
knee joint.  I've had knee surgery on both my knees to correct a
congenital defect and part of my therapy has been that as well.
Building up the thigh muscles will greatly take strain off the
knee by keeping the knee more stabilized.

Good Luck!
