Try doing some super light weights and go through the motion before doing some weight, I usually like to do 4 sets of 10 or 12. You might need to just build up some muscles that you might not have used often before. Start light, then move on, if the pain persists I would see a doctor.

Try doing a day of 15 reps for 4 sets and see if you still have the pain, try different stances as well. I personally never had the knee problem, I had the muscle right above the knee cap, it hurt like a bitch, it would cramp up in the middle of the night while sleeping and it would wake me up and I would be curled up like a shrimp sweating buckets cuz it hurt so much. But that goes away in time.
