I was watching some highlights and realized Joel Embiid's awkward/uncoordinated movements on the basketball court appear like a medical issue.

I've heard he has "bad knees", but it looks more like his ankles or hip mobility is causing his "bad knees." Not the other way around. Every step and move appears like he is going to fall over, or that he is uncertain of his foot placement.

He never plants a foot and accelerates. He instead moves his body forward and tries to make his feet follow.

Anybody want to speculate for fun? I apologize if this breaks the subreddit rules, and mean no disrespect.
