Bone marrow edema of the tibia is also known as a fracture of the tibia, but this fracture is relatively mild compared to what is commonly referred to as a tibial fracture. Bone marrow edema is commonly referred to as an injury to the bone trabeculae caused by external forces, resulting in bleeding and edema inside the bone, and therefore an abnormal signal on MRI, usually a high signal on the T2 signal or pressure lipid signal, which is reported by the imaging physician. The main symptoms of tibial bone marrow edema are pressure pain, localized percussion pain, and significant limitation of knee flexion and extension activities, which can induce severe pain when squatting, and limitation of knee joint activities when walking. Treatment is generally conservative, with external fixation in plaster and oral medication. If there is a combination of cruciate ligament injury or meniscus injury, surgery may be required.
