Replying to Will leg ever be the same?

Yea so i snapped my Tibia clean, and its been a month now and lookin at like two more till i can run

but i was talkin to my science teacher and he said the leg wont fully heal for like 15 years, then the calouse and everything go away.

but just wondering if this happened to anybody, were they able to come back next year or did it like hurt landing hard or awkward
