I followed Dr. Van & the PT instructions plus just a little more. If I started to hurt I informed them and would cut back. When in water therapy I walked the full hour. I did not stop to visit or rest. At three weeks I started walking up the stairs & then up and down, At 6 weeks I was hitting golf balls. At eight weeks I walked over 1 mile on the golf course.
I don't know anything more important than following the directions given by your doctor & PT
