I am afraid I don't have any experience with this injury. Perhaps others do. My guess it that you need to move it as much as pain permits. The knee will not be subjected to twisting forces in a properly done squat, nor would your kneecap. A light wrap to help things stay in place might not be a bad idea. Whether you do something like 5x5 squats, or 3x10, probably isn't important. If you can squat and it does not make it worse, I would train as normally as possible. Power cleans probably are off the menu for a bit.
