Both knees have been hurting,sharp pains on the inner parts and underneath the petella,my orthopedic surgeon told me to do pt, it didn't help, ideas?

Patellar pain: It's tough to help without seeing you but a simple start might be a patellar brace to stabilize your knee cap. patellar strapping by your therapist could also be tried. I would look at your feet as well, do you roll in excessively? If so orthotics may be of benefit. At your age with bilateral complaints it is unlikely that you have significant pathology but knee cap pain can be very difficult.
