What Is Bone Marrow Edema in the Knee?

Bone marrow edema (BME) is when normal fatty bone marrow—the spongy tissue in the center of bones—is replaced with a watery mix of fluid and blood. Also known as a bone marrow lesion, BME occurs when arthritis, an injury, or a fracture damages the normal bone structure.
