Patellar tendon tear

New ITRT 3 10 1

The patellar tendon, located in the knee, plays a crucial role in the movement and stability of the leg. This anatomical structure is quite special, as it is a strong band of fibrous tissue situated at the front of the knee.

Its primary function is to transmit the force generated by the quadriceps muscle to the tibia, allowing for the extension of the knee. Injuries to the patellar tendon, such as patellar tendinitis or a tendon rupture, can be debilitating and require appropriate medical attention for recover.

Challenges in the treatment of a Patellar tendon tear

The regeneration of the patellar tendon is an area of increasing interest in sports medicine and orthopedics due to the frequency of injuries to this structure. The patellar tendon connects the kneecap to the tibia and is essential for knee extension, crucial in activities such as walking, running, and jumping.

The most common causes of patellar tendon injury are:


Common in sports that involve repetitive movements such as running or jumping, typical of sports like soccer, basketball, athletics… the repeated stress on the tissue causes small tears that worsen over time.

Direct trauma:

Blows or falls can also damage this tendon, as it is just a connective tissue that transmits the force generated by the quadriceps to the tibia and is sensitive to impacts.


With the passage of time and the accumulation of circumstances, the tendon tends to weaken and become more susceptible to injuries. Nutrition and lifestyle also play a crucial role.

Medical conditions:

Diseases such as rheumatoid arthritis, diabetes, gout, psoriasis, or thyroid diseases, as well as certain antibiotics like fluoroquinolones, affect the health of the tendon.

Worldwide pioneers

In ITRT, we are global pioneers in tendon regeneration, meaning, creating new tissue to definitively overcome the injury. For the first time in history, we have scientifically demonstrated in a clinical trial published by the American Journal of Sports Medicine that our exclusive therapy generates new tissue in the tendon, contrary to what the global medical community believed.

Our exclusive therapy has shown 100% effectiveness, with absolute tissue regeneration in record time and without the need for bothersome surgeries that, in most cases, do not restore full joint functionality.

This is a groundbreaking therapy worldwide, based on over 20 years of study and research in Regenerative Medicine.

Why our treatment is one-of-a-kind?

Only ITRT applies the therapy that heals a patellar tendon tear

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:

Ensayos clinicos

Clinical Trials:

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.

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.



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.

Activación celular

Cellular Activation:

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

Otros donantes

Cells from donors:

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.

Second chance in a professional sports career

Carla López was a professional basketball player until she got an injury on the patellar tendon from her left knee. 

After 4 years of pain, she decided to get implanted with Cultured Stem Cells. In a couple of months, his tendon was regenerated and she came back to sports life. 

Nowadays, she lives a regular life, but she has changed the practice of basketball for weightlifting.
