Figure 3.

Pre- and postoperative radiographs of a 73-year-old female who presented with a rigid flatfoot deformity and painful degenerative arthritis of the talonavicular joint (stage 3 PTTI). Intraoperatively, a tear of the posterior tibialis tendon was noted. Left foot Achilles tendon lengthening, talonavicular joint arthrodesis, and medializing calcaneal osteotomy were performed, with improvement in the patient’s deformity and clinical status. PTTI indicates posterior tibialis tendon insufficiency.
