My bet is that JT had Syndesmotic screws removed during his 2nd surgery, these screws are placed from to the fibula to the Tibia to help the syndesmotic ligament heal. problem is these screws must be removed prior to allowing him to walk. usually 10-12 weeks. once screws are removed then walking can begin. Problem being if you walk with syndesmotic screws, then you run the high risk of the screws breaking.
