Yes: "bad knees" is a nonspecific description, but if you have knee pain with athletic activities you should avoid repetitive squatting or knee flexion, high impact aerobics and running, as well as sports that require cutting. Walking, swimming, and cycling are good activities. It is possible that this is a treatable condition. This could be determined by a trained professional and x-rays.

High impact sports: "bad knees" could mean any number of problems. Generally, low-impact activities such as swimming (+/- breaststroke) or cycling are safe.
