Abstract:
1. A method for reinforcing bone located in a bone marrow lesion in a subchondral region of a proximal tibia for treating the bone marrow lesion, the method comprising: identifying a subchondral defect in a subchondral region of a proximal tibia, the subchondral defect including a bone marrow lesion, the subchondral region occurring under an articular surface of the proximal tibia; creating, in the proximal tibia that contains the subchondral defect in the subchondral region, a subchondral injection path to an area in or adjacent to the bone marrow lesion for injecting an injectable fluid material into said area for reinforcing bone located in the bone marrow lesion, wherein said creating preserves an existing condition of the overlying articular cartilage of the proximal tibia and is conducted without further creating a void inside the proximal tibia in or adjacent to the bone marrow lesion; and injecting an injectable fluid material into said area via the subchondral injection path, wherein the injectable fluid material is a bone reinforcing material that is left in the area for becoming less fluid in the area so as to form, in situ, a bone reinforcing member for reinforcing bone located in the bone marrow lesion.
