I don't have a diagnosis, just a painful knee. Can I be evaluated?

Yes. The evaluation begins with your history and imaging. If you do not have recent imaging, your patient advisor will tell you what is needed and how to arrange it.

How is the treatment given?

Typically as a targeted injection into the knee, sometimes combined with intravenous delivery, in a single visit to our licensed clinic in San José.

Does this work for old sports injuries?

Injuries that never fully healed often lead to ongoing inflammation and early cartilage wear. Whether treatment is appropriate depends on what your imaging shows today.

When might I notice a change?

Responses vary. Some patients report changes within weeks; others over several months. We follow up with you on a set schedule.

Who is not a candidate?

Active infection, certain cancers and some other conditions rule treatment out. Your medical review determines candidacy, not this page.

Knee Pain & Injury Stem Cell Treatment

How stem cell therapy may help with knee pain

Knee cartilage has almost no blood supply, which is why a knee that has been hurt struggles to repair itself. Inflammation lingers, tissue quality declines, and pain becomes part of the day. Conventional care manages that pain. It does not change the environment inside the joint.

Mesenchymal stem cells are studied for their ability to reduce chronic inflammation in the knee.
Research examines how cell signalling may affect inflammation and the tissue environment. Evidence and clinical outcomes vary by application.
Treatment is delivered directly into the knee, where it is needed.
Cells are prepared in our own laboratory and used fresh, never frozen.
The protocol is written for your knee, your imaging and your goals.

Concerns to discuss with your care team

Pain that has outlasted the injury

Discomfort that persists despite rest, medication or physical therapy.

Swelling and stiffness

A knee that feels tight or warm, and takes time to loosen each morning.

Instability or giving way

The moment of doubt on a step, a slope or an uneven pavement.

The activities you have set aside

Running, hiking, tennis, gardening, the grandchildren’s games.

Who may be a candidate

Adults with chronic knee pain or a knee injury that has not resolved with physical therapy, medication or injections may be evaluated. This includes early osteoarthritis, old sports injuries and post-injury degeneration confirmed by imaging. Candidacy is decided by our physicians after a medical review of your history and imaging, never by a form.

Treatment is not offered where there is active infection, certain cancers, or other conditions identified in review.
