<qa>  What is the name of the surgical procedure that is implanted during a standard knee- Hyalofast with BMAC is implanted during either a standard knee arthroscopy or min-arthrotomy depending upon surgeon preferences and intra-operative findings. The lesion to be treated will be debrided to a stable cartilage margin. The defect will be sized and Hyalofast will be cut to fit the lesion area. If necessary, more than one Hyalofast pad can be overlapped to cover the lesion. 2 mL of BMAC will be loaded per Hyalofast scaffold and then implanted to cover the defect. Hyalofast with BMAC readily adheres to the site of application, but, if necessary, can be secured to the defect margins with an FDA-approved fibrin glue.
