Stem Cell Therapy for Ankles at RMI

If you suffer from chronic or acute ankle pain or instability due to arthritis, cartilage loss, ligament strain or tear, or tendon damage, then you may benefit from non-surgical stem cell treatments or stem cell-enhanced surgery.


Can stem cells heal ankle injuries?

Dr. Riordan and Dr. McKenna have published a case study in CellR4 Repair, Replacement, Regeneration & Reprogramming on treating severe chronic Achilles tendinopathy with bone marrow aspirate concentrate (BMAC), which contains several types of stem cells known to rebuild and vascularize tissue. 10 weeks after the ultrasound-guided injections into the tendon, MRI imaging confirmed significant healing. At 32 weeks, MRI images showed nearly complete healing.

Here’s what RMI patients have to say:

My right achilles heal tendon is back to normal again. I noticed a near immediate improvement within days of the treatment, with a return of a near normal gate. Now with gate fully restored, I’ve resumed all my daily activities as normal including taking long walks. Up hill inclines are no longer a problem.

Stem Cell-Augmented Achilles Tendon Rupture Repair Yields Excellent Results

In this study, 27 patients underwent surgery augmented with bone marrow aspirate concentrate (BMAC). 25 of these patients returned to their sport around 6 months post-treatment. Patients were walking without a boot in about 2 months and were able to participate in light activity at around 3 months. Excellent results, including no re-ruptures and early mobilization, were observed in this small cohort with open Achilles tendon repair augmented by BMAC. No adverse outcomes of biologic treatment were observed with this protocol.

What makes stem cell therapy at RMI different?



At RMI, we are augmenting BMAC with a proprietary, pliable tissue allograft (transplant) derived from human placental amnion, which functions as a biologic structural matrix to facilitate and enhance tissue healing and repair. It contains 108 different growth factors including more than 10 times the amount of WNT-4 and more than 60 times the amount of prostaglandin as competing products.

Prostaglandin inhibits inflammation, which occurs after injury and marks the beginning of the healing process. The faster we can tame this inflammation, the sooner the body can move on to the next phase of healing, regeneration.

WNT4 is arguably the single most important molecule required for wound healing.
