What is it?
What is knee osteoarthritis and how is it treated?
Knee osteoarthritis is the progressive degeneration of knee joint cartilage. It’s the joint most affected in recreational and high-performance athletes, as well as in people with intense daily activity, regardless of age. Previously there were only two paths: painkillers and physical therapy while waiting for joint collapse, or facing surgeries ranging from arthroscopy to the dreaded total knee replacement. Today, with the SANAA protocol, we halt the aggressiveness of the condition, restore joint function through stem cell transfer, and give our patients back an active, high-quality life.

Mechanism of action
How do Stem Cells work in this case?
The regenerative action works on four simultaneous fronts to address the cause, not just the symptom.
Differentiation into chondrocytes
Stem cells transform into cartilage cells that rebuild knee joint tissue.
Local growth factors
Release of molecules that activate repair and halt cartilage breakdown.
Anti-inflammatory modulation
Reduces chronic intra-articular inflammation that perpetuates pain and deterioration.
Synovial fluid restoration
Restores joint lubrication for smooth, friction-free movement.
