Abstract:
1. A method of reinforcing bone located in a targeted bone marrow lesion in a subchondral region of a proximal tibia for treating the targeted bone marrow lesion, the method comprising: identifying a bone marrow lesion in a subchondral region of a proximal tibia so as to establish a targeted bone marrow lesion for receiving treatment, the proximal tibia forming part of a knee joint, the subchondral region occurring under an articular surface of the proximal tibia, the targeted bone marrow lesion being less than 10 cm from the knee joint; creating, in the proximal tibia that contains the targeted bone marrow lesion in the subchondral region, a subchondral injection path to an area in or adjacent to the targeted bone marrow lesion for injecting an injectable fluid material into said area for reinforcing bone located in the targeted 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 targeted bone marrow lesion; and injecting an injectable and curable 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 targeted bone marrow lesion, wherein said identifying includes identifying the bone marrow lesion through use of magnetic resonance imaging (MRI) of the knee joint or a Technetium-99 bone scan of the knee joint.
