Most of you guys know this but for maybe some that don't. Full squats to at least parallel are the safest way to squat and protect your knees. Partial reps generate a lot of shear force forward through the knee. Stopping short of parallel places the knee joint in a vulnerable position. I try to go at least parallel or below all the time while squatting. Foot stance and angle also have a lot to do with pressure on the knee joint. At least shoulder width apart and toes angled outward slightly will maintian the knee and hip alignment needed to protect the joint. Also buckling your knees inward while trying to come out of the bottom position compromises your knees, it is also a sign of weak inner thighs. Wide stance leg presses will develope your inner thighs and help with your overall squats. knee wraps are probably more of a security blanket for BBers unless you are squatting mamoth poundages. It causes compression of the patella against the top of your tibia and the bottom of your femur. This will cause irritation of the smooth coating over the glide points of these two bones. you end up pushing the synovial fluid out of the gap between the patella and your knee joint. Wraps are fine for 1-3 reps very heavy but if you are consistantly doing heavy 6-10 rep work, eventually you will have trouble. Hope this is a help to all you poor kneed squatters and those that avoid squat and make excuses, well you will never develope a strong dense physique with out squats.
