There are two forms of cartilage in the knee; the two meniscal cartilage discs or cushions, and the articular cartilage on the ends of the bones. Some physicians might be referring to a meniscus tear.
When a surgeon says you are “missing cartilage” in your knee, more often than not, he or she is referring to the articular cartilage on the end of your bone.
