General comment: I had a torn meniscus, arthritis pain, and floating cartilage in my right knee with progressively worsening pain that made it hard to walk. Cortisone shots did not help. I had knee scope done in fall of 2017, not much improvement in spite of following all the PT exercises for about 6 to 7 months. Tried the synvisc series of 5 injections spaced a few weeks apart, got very temporary 15 to 20% relief. Finally had TKR done fall of 2018. “Normal” recovery and pain levels, end result a mostly pain free, very flexible, strong, knee that lets me do 85% of what I want/need. No jogging, no singles tennis on hard courts, no downhill hiking (uphill is ok... haven’t found a trail with down elevator yet), no kneeling (pain, not forbidden). All in all, it turned out well for me.
