Abstract
The technique of arthroscopy is, at the present time, available for the investigation of the subtalar joint. In this preliminary report, the relevant anatomy and technique are reviewed. Illustrative cases are presented to review some of its applications. It is the conclusion of the author that arthroscopy of the subtalar joint may be of value in the following situations: (1) assessment of the articular cartilage in suspected cases of degenerative, rheumatoid, or infectious arthritis; (2) evaluation of chronic pain syndrome in the hindfoot after injuries; and (3) biopsy of the synovial lining, breakage of adhesions, joint lavage, and removal of loose bodies.
