Yeah. It’s been a bit too long to simply be an ankle sprain IMO.
Then again, it could be what’s commonly called a “high ankle sprain” aka syndesmosis sprain. Those take quite a while to heal vs the traditional ankle sprain, aka anterior talofibular ligament sprain.
But watching the video, it’s not how a high ankle sprain usually occurs. High ankle sprain usually occurs with a foot somewhat planted and twisting around it. Stranger things have happened though. I’ve seen things and thought because the mechanism of injury, it would be a classic whatever injury, only to get proven completely wrong by imagining.
I remember one of my former team orthopedists giving me a very hard time about mis-diagnosing an ankle fracture that ended up needing surgery. The doc looked at me and said “how could you possibly mistake that? How long have you been doing this job?” He was a real a-hole. So I said “well, his mechanism of injury was (insert long jargon here) and he walked off the field on his own and didn’t complain of pain for 2 hours. I can show you the video if you’d like. And I’ve been doing this job for 10 years now, thank you.” Doc looked at us, shrugged his shoulders, and said “no idea how you broke that by doing what he said. No idea how you walked off on your own. No idea how it didn’t bother you that much for 2 hours. But I guess stranger things have happened.”
I really hated that doctor. But he’s honestly one of the best orthopedic surgeons there is. And he won’t hesitate to tell anyone who asks either
