What is CARGEL Bioscaffold?

CARGEL Bioscaffold is an easy, ready-to-use product applied during a single-step bone marrow stimulation procedure. It is easily prepared by mixing a buffer, a chitosan solution and the patient’s whole blood to create a liquid bioscaffold, resulting in superior cartilage repair.1,2

How does CARGEL Bioscaffold work?

  • Physically stabilizes a more voluminous blood clot
  • Provides structural framework for subsequent cellular ingrowth
  • Impedes blood clot retraction
  • Generates an adhesive bond between clot and surrounding cartilage

    Why choose CARGEL Bioscaffold?
