The proximal anterior cortex, instead of the lateral cortex, is drilled to access the bone marrow lesion seen in the posteroinferior aspect of the right femur on fluoroscopy with the patient lying supine, thereby stimulating bleeding of healthy proximal bone and introducing biologic tissue to the lesion. (A, B) Anteroposterior view of biologic route. (C) Lateral view of biologic route on fluoroscopy.
