"I now wear my ear in my knee" - Marianne Hartl on her innovative stem cell treatment at the ROC

The well-known folk music duo Marianne & Michael Hartl relied on the ROC Regenerative Centrum in Aschheim near Munich for orthopaedic complaints - with great success.

Marianne Hartl suffered from severe knee pain for years. Thanks to the innovative stem cell therapy with the AMT procedure, carried out by Dr. Daniel Filesch, she finally became pain-free: "I now wear my ear in my knee," she says with a smile - because the body's own cells for the treatment were taken from behind the ear. She is delighted that she can now finally play a full 18-hole round of golf again.

What is the AMT procedure?

The Autologous Microtransplantation Technology (AMT) is an innovative and non-surgical method for treating joint pain and regenerating cartilage tissue, particularly in diseases such as arthritis or arthrosis.

How does the AMT procedure work?

1. Tissue removal:
   First, the body's own cartilage tissue is removed from the ear cartilage - this contains a particularly large number of regenerative progenitor cells.
2. Preparation & transplantation:
   The removed tissue is specially prepared and then injected minimally invasively into the affected joint.
3. Regeneration & pain relief:
   The cells promote the natural regeneration of cartilage - often with a significant reduction in pain and improved mobility.

Michael Hartl also found support in the ROC

Michael Hartl received a Racz catheter treatment for targeted pain therapy in the spine. The flexible catheter reaches the segment of the spine that causes the pain. Anti-inflammatory and pain-relieving medication can be administered to the inflamed and partially compressed nerves through this catheter. The accompanying physiotherapy Michael Hartl receives at INTAKT - directly on the 1st floor of the ROC Regenerative Center.

In an interview with ganz-muenchen.de, the two talk openly about their experiences:
