before injury, good. post, not so much. Your "lumbar arch" still isnt there, you lean forward when you get low, and it becomes evident when you press back up, you lower back raises before you chest. Also when you first go to lower, your chest dips forward, which should not be so. looking up at the ceiling tends to fix this problem. Much better form than your previous post tho, good job at controlling transverse (forward/backward) movement.
*i may be nit picking only cuz squats my favorite lift
