This is probably something to be brought up with your doctor if you know that you are a preexisting condition.
Things that can help, a knee brace or wrapped the knee may help keep it in place. Go to a running store where they measure your feet and get fitted for a GOOD pair of running shoes. I think there is some rule about not increasing over 10% per week or something like that. Doing too much too soon ends up injury. When I started running I did too much too son and suffered for 3 months from runner's knee. If it hurts stop. No pain no gain is not true. Your rest days are just as important as your run days.
Congrats and I hope you can run. It's such a great stress reliever!!! Good luck!
