I've got deteriorated cartiledge in both my knees. I used to do deep knee squats with a lot of weight. (@ 600 lbs) I get a throbbing ache when the barometer drops. (my own built in rain indicator).
The Orthopedic instructed me to stop the squats and do some leg extensions and leg curls only. He also instructed me to ride a bike to help strengthen the knee area w/ minimal impact.
If you're having knee pain, on the bike it can be a couple of different things. Your seat can be too low or too high. I measure by putting the pedal in the 6 o'clock position and place my heel on the pedal. Set the height to where the knee locks out. Then, when you ride with your pedal on the balls of your feet, your knee will NOT lock out.
The other thing to try out are clipless pedals/shoes with a lot of "float" Time A.T.A.C.'s and Eggbeaters have a lot. Speedplay Frogs probably have the most.
If you also ride a road bike, look into Speedplay X-Series pedals.
The final thing to check is your fore and aft position of your saddle. This is a debated issue, but I always use it as a general rule of thumb. (You'll need a helper for this). With you foot clicked in, and your pedal in the 3 o'clock position drop a plumb line (a string with a heavy washer works for this) down the front of your knee. The plumb line should be in line with the pedal axle. If not adjust the saddle fore or aft on its rails to get it to line up.
O.k., another thing I thought of, not directly related, but all part of bike fit. Make sure your cleat is below the ball of your foot. If it's too far back, your leg will be too far forward and you could get some associated knee pain or "hot feet".
