Arthroscopy of the calcaneocuboid and talonavicular joints.

The authors describe the anatomy, portal placement, technique, indications, and preliminary results of seven cases of calcaneocuboid or talonavicular joint pathology that underwent elective investigational diagnostic or therapeutic arthroscopy with a follow up of 3-14 months. All patients had failed available conservative therapy. Results of treatment were five excellent and two good cases. Two patients required arthrotomy. There were no complications associated with portal placement, arthroscopic technique, or instrumentation. Arthroscopy of the calcaneocuboid and talonavicular joints has proven to be a relatively safe and valuable diagnostic and therapeutic tool. It is hoped that advances in small joint arthroscopy application will encourage further technological evolution in arthroscopic instrumentation and establish a foundation for further arthroscopic exploration of the small joints of the foot.
