My daughter did 10 years of PT, taping, etc. etc. and PRP literally cured her overnight. For both SI joint and, later, the knee. But you need imaging and it doesn't work for everyone. I would think it would help you. Hope you find a good provider! For my daughter it was a miracle. She may need another one but it has lasted 6 years.

I have a torn meniscus in one knee that I had scheduled for surgery, but got a second opinion once pain subsided. Delayed surgery and continued with conservative treatment, then PT. I was able to resume my normal routine without pain and even began a daily workout regimen. I do have occasional pain, but not severe. I’m interested in PRP too, though. Will be interested in responses you get.

My sister in law had the prp injection which insurance did not cover. It didn't help and she got a knee replacement. Maybe for a torn meniscus you just need arthroscopic surgery which my husband had for 2 tears and did very well . It's been at least 9 years.

Prp was considered experimental ,so insurance did not cover it. That was 4/5 years ago. And very costly!

Having the first of three procedures done a week from today. Don’t know how long it takes to be effective, but I’ll update when I have something.

It works pretty quickly. We did pay $1,000 but saved on PT! It was recommended by mainstream, to doctors at Mass General and Spaulding in Boston.

I'm due for a second injection in three weeks. My (tennis elbow) looked ugly on the ultrasound, comparing the injured elbow with the non-dominant arm elbow; was scheduled for surgery back in 2016 but my insurance company screwed up and I had non-refundable tickets to Brazil at the time so I couldn't affor to wait. I did some PT before getting my first injection at the VA in Palo Alto and it eased the swelling and discomfort a bit. I'm hoping this time I'll be ready to play tennis in another six weeks. I have Parkinson's Disease and had to stop surfing, my life since I was a 12-yr-old, but I had too much trouble balancing and popping up on my boards, so I just gave it up. I've been working hard to keep from declining and know that I'll never get better, but looking forward to playing tennis gives me hope--an important tool for aging (I'm 73) and have been an athlete my entire life. I'll let you know how the second injection works out.

@cadunkin, in addition to the responses you have received, I also moved your discussion and combined it with another one titled "PRP (platelet rich plasma) injection?" - https://connect.mayoclinic.org/discussion/prp-platelet-rich-plasma-injection/ so you could read even more responses and experiences on PRP injections.

@cadunkin, was there another treatment route suggested to you that you are hoping to avoid by learning more about PRP injections?
