I agree that this is something you should discuss with your surgeon. I'm not sure exactly what you're describing when you say the knee "pushes out" when you squat. I'm thinking that's something that would need to be seen to determine if it was cause for alarm. If there is no pain with that movement, then it probably is not an issue. If the throbbing comes on when doing a specific activity or exercise, try stopping that for a few weeks and see if the problem resolves.
