I am writing this post while on the plane back home.  It is Saturday October 14.  Thursday and Friday repeated the minimum pain I had on Wednesday.  Don’t get me wrong here- in certain positions and with certain motions the knee can be very painful.  For example I can bend the knee to 95° and when i push past that the knee pain is real.  This is to be expected.  Also, while walking I need to be aware the the quadriceps, the muscles that are on the front of the thigh and help you stand, are still not fully recovered so I step slowly.  I graduated to crutches and can even walk without any assistive device 5 days after surgery.
