Correction of Severe Flatfoot Deformity by 3-Portal Arthroscopic Triple Arthrodesis.Arthrosc Tech. 2020 Jan; 9(1):e103-e109.AT
Severe flatfoot deformity with lack of coverage of the talonavicular joint is frequently treated by triple arthrodesis. Various arthroscopic triple arthroscopic techniques have been described to reduce the extent of soft-tissue dissection. The purpose of this Technical Note is to describe the details of 3-portal arthroscopic triple arthrodesis for correction of severe flatfoot deformity. This approach allows thorough preparation of all fusion surfaces, and the bone removal by decortications facilitates reduction of the talonavicular joint and correction of the forefoot supination.
