I worked with an experienced personal trainer 3x a week for 6 mos after PT and now see the trainer 2x per week. I went to a respected Ortho surgeon for a 2nd opinion just last week. He told me up to 20% of people have pain following the procedure and encouraged me to do daily leg lifts to continue strengthening the VMO area of the quad muscle. It is very frustrating as I should have my left knee partial redone to a total, but I am very fearful.
