cartiform implanted in a human where this product was used. It's a viable cartilage mesh that we've been able to engineer here at Osiris. And we use it for fixing cartilage defects. And so where a patient loses their cartilage, it'd otherwise progress to osteoarthritis or in a lot of cases, need a knee replacement. Here, we're able to resurface that cartilage. And this is just a great picture of how Cartiform gets implanted and how it fits into articular cartilage defect.
