Subchondral fractures are not only common after ankle injuries, but are also missed or not seen on MRI examinations. The subchondral bone is very important since it supports the articular cartilage that has no blood supply of its own. During this ankle arthroscopic procedure Dr Moore uses a Calcium Phosphate product (Tactoset - https://anika.com/medical/products/tactoset/ ) to fill the void created from this patient's chronic subchondral fracture pain at the talar dome and neck interface. After mixing the solution, the viscosity is low and has the ability to 'back fill' the area where the cannula is inserted as well as other adjacent areas as seen at the end of this video.
