At ITRT we are world pioneers in Achilles tendon regeneration, that is, we can create new tissue to make an injury permanently a thing of the past. For the first time ever, we have proven scientifically what we already have seen in our daily clinical experience: that tendons can have a second life.
We have clinical experience with virtually every tendon in the human body, namely the patellar tendon, the Achilles tendon and the Harmstring, to mention just a few. MRI from a 86 years-old patient is included below. He presented a frayed Achilles tendon, with a 3 cms break. The evolution of the injury after treatment him with cultured stem cells can be observed. 8 months later, the injury was virtually healed and 24 months later, the tendon was brand new and completely unlike the previously frayed tendon.

Not all stem cell treatments are equal; many of them barely contain a handful of stem cells, at best.
Our exclusive therapy of cultivated stem cells is the only one in the field of Regenerative Medicine that has scientifically demonstrated its effectiveness and safety. Only ITRT applies this therapy, which is the result of over 20 years of research.
Differences of our exclusive therapy from the rest of the mislabeled ‘stem cell’ treatment:

We have scientifically demonstrated in clinical trial that only by using millions of units can the regeneration process be activated. Our therapy applies millions of stem cells, certified by our laboratory.

Over the course of more than 20 years, we have conducted 23 clinical trials that have demonstrated the efficacy and safety of our therapy, constituting the largest knowledge base worldwide in regenerative therapy.

There are many types of stem cells, but we have demonstrated that only 3 of them are effective when applied to tissues. In the laboratory, we select the correct types of stem cells to ensure regeneration.

Once the appropriate stem cells are selected, the very small quantity obtained through isolation undergoes an activation and culturing process, causing them to begin multiplying until reaching millions of units.

We have demonstrated in several clinical trials that we can use stem cells from other donors. This fact is very important especially for elderly patients, those with urgent needs, or serious illnesses.

Lluis Marsà was a great lover of tennis, to the point that at the age of 75, he still continues to practice it.
When he was 59 years old, he ruptured the Achilles tendon in both legs, which seemed to be the end of his favorite hobby.
After learning about the treatments that other elite tennis players had undergone, he decided to turn to ITRT to have 20 million cultivated stem cells implanted in each tendon.
Today, 15 years later, he continues to play tennis competitions and enjoy his favorite hobby.

Manuel Monzó, 74-years-old patient, had been suffering pain for 10 years, because of a rupture on the Achilles tendon.
For the first time in history, 20 million cultured stem cells were implanted in the Achilles tendon. After 8 months his injury had almost disappeared and a year later he had a brand new tendon.

ITRT has just presented the results of a clinical trial with cultured mesenchymal stem cells that show, for the first time, that tendon can be regenerated.
The results indicate an unprecedented degree of regeneration of the tendon structure in 100% of patients, who resumed their practice of sports within 2 months.
The prestigious American Journal of Sports Medicine, has recently published the results and acknowledged them as “one of the most outstanding advances of recent decades”.
