I did PRP on both of my knees two years ago it did not help my left knee but did wonders for my right in October I had a new procedure done it’s called MFAT this is where they liposuction some fat clean it up and then inject that into the joint it has done wonders for my left knee. I am very religious with my exercises and stretches and have found the book Built From Broken Very instrumental in setting up my program. Unfortunately this is out of pocket and for one knee it was $3500. The other disadvantage is there are no long-term results so I’ll let you know in a year if it was worth it right now I’m headed to Pickleball
