Video Summary

Brian Waterman and Cassandra Lee demonstrate an arthroscopic MACI (matrix-induced autologous chondrocyte implantation) technique in a cadaver knee. They review the single-use instrumentation kit: multiple curettes (rake, square, ring), cannulas, a deployable dam to create a dry field, a lesion-prep cutter with adjustable oscillating positions, toothless forceps, cutting board, implant cutter, and silicone-tipped sponges for gentle graft manipulation and drying. They emphasize portal placement to achieve an orthogonal approach to the chondral defect, aggressive fat pad debridement, and use of accessory portals/traction sutures to obtain vertical lesion borders. After templating and preparing the defect, the cell-seeded membrane is cut (cell side up) and kept in saline until implantation. The joint is dried, fibrin glue is applied sparingly, and the graft is delivered with a V-shuttle, adjusted to avoid overhang, tested through range of motion, then sealed with a fibrin-glue perimeter. Indications discussed: isolated femoral condyle/trochlear (and possibly tibial) lesions ≤3 cm, typically without major concomitant procedures; tourniquet use is preferred. They also describe obtaining a full-thickness cartilage biopsy near the lateral notch/ACL during initial arthroscopy.
