After I do squats they throb for about an hour but other than that nothing big. I do get pain from cold weather because of the titanium screws I still have in there. Plus the ones in my left hand get cold as hell too.
I was lucky enough to rehab my knees with a lot of machine work (air machine leg press before full squats) , I just started using a new hack squat machine though and am sure that'll be knocking again before too long.
