Fig. 4. At 18 postoperative months (A), valgus ankle arthritis was developed on the left side while the talar tile on the right side was intact. On the hindfoot alignment view (B), valgus malaligned hindfoot was shown. A valgus deformity was corrected on with varus stress (C). A standard load of 150 N was applied to the ankle joint using the Telos device (METAX, Hungen, Germany). Using 3-dimensional computed tomography (D), we found a bony contact with subchondral cyst formation on the lateral side of talar dome and tibial plafond.
