Regenerative Medicine for Knee Arthritis at Riordan Medical Institute – Roger Brown

Riordan treatment protocols combine a patient’s own bone marrow stem cells with an amniotic membrane tissue product called Signature Matrix and/or an umbilical cord tissue product called Signature cord to treat bone, muscle, tendon, ligament and cartilage damage in the knee. The amniotic we use is composed of collagens and other structural proteins, which provide a biologic matrix that supports angiogenesis, tissue growth and new collagen production during tissue regeneration and repair.

Dr. Herrera – How are you doing today sir?

Mr. Brown – I’m doing fantastic.

Dr. Herrera – We recently did a couple of knee injections approximately a year ago in March of 2019 for some bad arthritis. I just wanted to kind of do a follow up to see how things are going. Just kind of tell me what’s happened over the last year.

Mr. Brown – Well, before I had the injections, I had a problem particularly going down stairs. I had knee pain. Sometimes, I would have that coming up stairs. So I investigated this and I came up here and y’all injected me the same day I came up here. And today, I finally returned to see what the follow up looked like. I knew I didn’t have any pain but I just wanted to see what it looked like on x-rays. I’m shocked frankly. I can see that the space that formerly was there almost bone-to-bone is no longer there.

Dr. Herrera – So, as far as resolution of pain, how would you quantify that? Do you feel like, 0 to 100% scale, do you feel like…?

Mr. Brown – Zero pain.

Dr. Herrera – Zero pain?

Mr. Brown – Zero pain.

Dr. Herrera – Okay, great.

Mr. Brown – And I work out.

Dr. Herrera – And you’re working out so your quality of life is better?

Mr. Brown – Oh yeah.

Dr. Herrera – Your functional daily activities are much better?

Mr. Brown – No problem.

Dr. Herrera – I’m so happy to hear that.

Mr. Brown – I’m thrilled to death.

Dr. Herrera – [unintelligible] Well, I’m so glad that you’re able to share this with us and glad that we were able to help. Anything else? Any, …you know, a lot of patients will come in and be apprehensive about what we do and things of that nature. Do you have any reservations or advice for patients…

Mr. Brown – No. I have no reservations whatsoever. I know it worked. So, there’s not any question of that. I don’t take Ibuprofen. I don’t take Aleve. I don’t take anything… for that problem that I’ve had. And, I’m fine.

Dr. Herrera – Well, that’s great news.

Mr. Brown – And I’m 84. [laughing]

Dr. Herrera – Amen! That’s beautiful. Thank you for sharing.

Mr. Brown – And I’m not pregnant! [laughing]
