A male patient, age 29, had sprained left ankle joint previously (3 years ago) during practice and subsequently suffered repeated sprains. a and b The results of stress position fluoroscopy indicated that a talar tilt angle range to 23° with the subtalar joint instability. c Sagittal and d coronal views of MRI indicated that the structure of the ATFL was damaged (yellow arrow), and CFL was chaotic (white arrow). e and f Arthroscopic views of the operative site. Severe ligament remnant scarring was found by arthroscopic observation. Suboptimal tendon quality and the semitendinosus tendon transplantation was performed. g Sagittal and h coronal views of MRI indicating good tendon graft for ligament reconstruction at a follow-up 24 months postoperative. Interface screw, ATFL, and CFL were as indicated (white arrow)
