Steve is correct (as usual). Squatting below 90 degrees activates the glutes & hamstrings for most people, and the hamstrings provide pull the tibia into the knee joint, providing compression and stability for the knee. Squatting only to 90 degrees and reversing direction to go back up before the glutes and hamstrings are activated leaves all the force on the quads and the ligaments in the knee, which are not as stable and can be injured relatively easily. Squatting deep is good- but make sure you have good form. Proper back and neck position, hip angle, knee/feet angles etc. are all important. Find someone who can teach you properly if you're not sure how.
