Regenexx Healthlink Center in Beverly Hills. I did not get much bang for my buck. Pretty disappointed with the stem cell and PRP results. It was over $7,500. They will do a repeat for $3,800 but I have little confidence that it will not be a waste of money since the first treatment did seemingly nothing to tighten my ACL. The meniscus got better somewhat, but how much that had to do with the treatment, I have no idea. Also, the stretched LCL had some improvement, but again, not clear how much of that was due to the treatment. There was a post op regimen they told me to follow. I wore a very tight brace for over two days and did not do any extreme or aggressive workouts. I did do cycling as I was instructed but, to no avail...
