BioCartilage (BC) is dehydrated, minced human hyaline articular cartilage that was developed as an adjunct to microfracture surgery to help stimulate the bone marrow and stem cells to form hyaline-like tissue in full-thickness chondral defects. The minced pieces of BC require a dry environment for application and can easily be disrupted by residual moisture of saline solution in the surrounding tissues. We present a technique of carbon dioxide insufflation during knee arthroscopy as a means of maintaining a dry environment for preparation of the bony bed during BC augmentation of microfracture surgery. This technique is safe and provides more than adequate visualization, as well as a dry environment, to make the arthroscopic application of BC significantly more efficient.
