Abstract

Injuries involving damage to the articular cartilage and subchondral bone of the talus may result in a talar bone cyst. These subchondral cysts generate chronic pain and swelling that can interfere with patient’s ability to perform both daily and recreational activities. Current treatment options are invasive and do not effectively prevent cyst recurrence. Here, we present a surgical technique for the treatment of osteochondral lesions of the talus with persistent subchondral cyst. This Technical Note describes the arthroscopic injection of hyaluronic acid−based calcium phosphate to fill the bone cyst and promote bone remodeling. This technique is a minimally invasive treatment option that stimulates surrounding native bone resorb and replace the bone void filler. [Display omitted]
