To be perfectly honest with you what you read is crap. Squats will never screw up one kness, unless you bounce at the bottom and or raise the heels up on a low block. NEVER raise the heels up as this puts much stress on the knee. Learn to squat with a flat foot. This will work the entire thigh very hard.....get the flexibility in the calves and you should be able to do it. Most of the time one needs to squat until the TOPS of your thighs are at parallel or very slightly lower ,and leg press as deap as your lower back can take.
(there is a place with the advanced trainee for partial squats, AT TIMES)
Problem is some people do not have the needed flexibility in the ankles and or have very long legs in compaired to torso and these can prevent good squating form. These people lean too far forward and hurt their backs. Some people can never squat safely even with flexibility work(Few though) Also, some leg press machine will kill the lower back if you go deep....use the Hammer Strength leg prees if you can as it is a great one.
Injury almost never come to the knees with squats and leg presses.....injuries are almost always in the lower back.
The very best squaters go quite low and the best squater I ever saw went ALL the way down much of the time(Tom Platz)
If you do not go fairly deep you will not develope the quads, hams AND glutes much.
Hope this helps.
