It depends on what exactly the problem is with the knees.
Some people find that impact is the real issue, and by avoiding higher impact activities like running, walking and jumping, they can still bend the knees comfortably, and cycling (whether outside or an exercise bike), elliptical, etc still allow them to get in a great workout.
If bending the knees is a problem, then perhaps swimming or water walking is a better option.
Spark's Limited Mobility Lifestyle Center also has a range of suggestions for seated workouts.
But I would encourage you to speak to a physical therapist who can recommend exercises specifically to strengthen your knee, taking into account your specific condition.
Also, as you lose weight, there is less stress and force on the knees, and this may help also.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
