(A) Via the anterolateral viewing portal, BioCartilage mixed with 1 mL of bone marrow aspirate concentrate (white star) is injected arthroscopically through the trocar and smoothed with the paddle portion of the trocar (white arrows). (B) Throughout this process, an assistant (black star) intermediately applies suction through the inferior spinal needle via a Frazier-tip suction device (white arrows), keeping the working area free of fluid. (C) Once the BioCartilage has been applied, fibrin glue (white star) is injected over the filled lesion via the superior spinal needle (white oval), sealing it in place. (D) Fibrin glue (white star) is given time to harden prior to removal of the scope and closure, and the remaining bone marrow aspirate is injected into the joint after closure of the portals.
