Arthroscopic treatment of transchondral talar dome fractures.

Fifteen cases of transchondral talar dome fractures treated arthroscopically at the Naval Hospital in Oakland, California, were reviewed. Roentgenograms and results from clinical examination were assessed preoperatively and at regular intervals postoperatively. Clinical followup of 18 months was obtained in all cases (range, 18 to 36 months; mean, 26 months). All lesions were treated with arthroscopic excision of fragments with abrasion and/or drilling of the remaining crater. There were nine excellent results, four good, one fair, and one poor. There were no complications. Results of arthroscopic treatment compare favorably to those of open arthrotomy.
