    It depends on how you define "bad knees." If you have constant knee pain, or constant stiffness, mobility problems, or flexibility problems, it can help determine what kind of treatment you may need. Remember that surgery and/or knee replacement is a last resort. The worst thing you can do for your bad knees is to sit and do nothing all day because that promotes atrophy of your thigh muscles, which is important for your everyday mobility. The exception to this is that if you have an overuse problem like knee tendonitis, then resting would be a good idea. Talk to your doctor so you can isolate the real problem with your knees so you can get an appropriate treatment.

    Hope this helps!

    Harold, at age 82 many people have bad knees. The most common reason is osteoarthritis (OA). If you are being followed by a doctor, and you probably should be, discuss your options with him/her. As suggested by Mr. Chun above, strength is important as strong muscles serve as shock absorbers for the joints. But if OA is bad enough strengthening can be difficult. People who are experiencing pain that limits their ability to function independently at home and in their community often benefit form a knee replacement. Knee replacement is one of the most safe and common surgical procedures and the improvement in pain and function can be life changing. However deconditioning from lack of activity can delay and affect recovery from knee surgery. People who really need a replacement could delay too long. After surgery a physical therapist would help with rehabilitation.

    I hope you are able to continue with your independent lifestyle.

    Good luck.
