What does this mean? i have a small subchondral fracture deformity of the lateral trochlear facet with prominent bone marrow edema throughout the regi

Cartilage damage: Prominent marrow edema of the lateral trochlea means that the cartilage covering the bone in this area is injured or worn thin. This is a common place to develop arthritis which causes marrow edema when the cartilage gets too thin or is worn out and bare bone is exposed there. If you had a recent injury, it could be cartilage damage rather than arthritis. See your provider for recommendations.
