I had a scope in Oct 2017 for medial miniscus tear, and stage IV OA. I went to PT for 3 months, twice a week. I still cannot work. My knee swells to the size of a grapefruit to where I can't bend it, it is warm and so painful. Today I had 20cc drawn from the knee and a Cortisone shot. The doctor says next up (if this doesn't help) is the hyaluronan series. Just wondering if it's more painful than the Cortisone shots I have had before, and now after, surgery.
