Not bad at all. Did the usual drill. He measured me. Right knee (worst of 2) was at 90. left knee 96. Works for me. Flex at 0 both sides. Anyone who is pre-op and reading this: Stretching and quad build up BEFORE surgery helps! And certainly some blessings of God and prayer. Anyway, No bike or weights today. Next time. Wed. i think without looking at the calendar. pain not to bad after my "workout." I was sure to ice up real good before i even left PT. I'll just relax now for the eve.
