Tips for Arthroscopic Treatment With Microfracture and BST-CarGel

Tips	Reasons
Thoroughly remove protruding synovial tissue to facilitate visualization of the defect in the horizontal position.	Compromised visualization and/or contact of synovial tissue with the lesion site might impede application of the biomaterial.
Debride the damaged cartilage down to the subchondral bone with removal of the calcified layer.	Remaining damaged tissue may compromise repair tissue formation.
Dry the defect with suction or with a swab.	Dryness of the defect bed is crucial for adhesion of the BST-CarGel.
