Re: Injured knee…
I’d be inclined to see if there is a reason for re-occurrence first, albeit 7 years ago. I suspect hamstring strength (or absence of) may be a contributing factor which would influence the graft for me.
The dilemma about where to take the graft from is interesting and some will tell you different things, but in most cases the patella tendon is used.
You may benefit from, in an ironic way, having the graft from the opposite knee.
The other question is age and length of playing career – and finally if you can play without an ACL.
It is possible and depends on how long you want to play on for.
