Benign cystic lesions of the talus are relatively rare and must be differentiated from degenerative cystic lesions associated with osteochondral injury or established osteoarthritis. Patients may often attribute the associated ankle pain to a previous minor injury and this may erroneously lead the clinician toward treating a ligamentous injury.

 

The gold standard surgical management of a talarintraosseous ganglion has been open debridement, curettage and bone grafting with good result. The diagnoses include unicameral bone cyst, more commonly seen in children and intraosseous ganglion seen more commonly in middle-aged adults. Arthroscopic treatment of a variety of ankle conditions has gained popularity and widespread acceptance due to the reduced morbidity and more rapid recovery associated with the technique.
