ACL surgery recover time for someone highly active?
I realize that everyone is different and it depends on the severity of ACL injury to estimate the recovery time. But I wanted to see if anyone has ever been in this situation.

My fiance tore his ACL around 3 years ago. And even re injured it a couples of times. But that has not stopped him and even with it damaged he has always been highly active.
Even with a torn ACL he runs, weight trains, rock climbs, does different types of martial arts, etc, and basically involves himself in very intense activities. Every now and then he does wears a brace when it starts bothering him or giving him problems.

Tomorrow he’s getting ACL surgery and I was thinking that maybe his recovery time will be quite fast due to it not stopping him from being highly active. I was wondering if anyone has even had a torn an ACL while still capable of being highly active and then received surgery? How long was it until you were capable of normally walking again and going back your your intense physical activities? Oh and how long was your surgery?

Thank you!
