Strengthening muscles after total knee replacement revision, what to do?

Your PT should be --: Able to help you, as he/she'll be able to determine which (or all )muscles need to be strengthened in your thigh (both quads ; hamstrings). They'll be gauging your response to the pt and giving you a home exercise program, all in an effort to rehabilitate you, to attain the best function you can achieve after rev surgery. Do them religiously ; you'll enjoy the results of the surgery. Good luck.
