Knee ligaments are their strongest at full flexion or full extension, they've evolved to be able to support us standing and squatting. Non-acute knee problems are often found in people who are unable to do this type of squat, as limitations in ankle and hip flexibility (often combined with weakness in these parts) puts a large(r) strain on the knees.
