Osgood schlatter's disease anybody? My knee's started to makes noises when I squat with weights. Pretty sure that's not normal... no more squats and back to the med for me I think.
My knee clicks too - however, if you're experiencing knee pain squatting, it could well be to do with your form in the rack - I squat 3x times a week, pretty heavy on Mondays and Fridays and my knee is never sore after (though it does hurt post riding brakeless pretty often). Squatting can really strengthen your knees and legs, but ONLY if it's done right... The biggest improvement I ever made in mine was going from an Olympic style (on the traps) squat to a more powerlifting (Low-Bar) squat. It forces you to use your hams, glutes and posterior chain far more, and take the stress off your knees as you push your knees out over your toes and let your butt do the work. Also make sure you always go DEEP!
