A 8 months ago I had PRP done to my left knee. The pain seemed to subside, to a comfortable ache, could live with it. Then 3 months ago using rpthe Harvest system, I had the right knee done. (Having OA bilateral knee) The Harbest program was much better. However, it was very painful for 2 days. Now, I'm about 90% good. Just yesterday, we redid my left knee using clear PRP. I have to say that, 1) the clear hurt for a couple minutes, and I limped a little, but cleared quickly, 2) I feel the clear absorbed better into the joint, and this morning I am feeling pain free. I know this is only a temporary fix, as I think TKA is in my future. But for now, I'm happy. Anyone else have PRP discussions?
