you mean you haven't realised that they removed your kneecap??!!?? =D

A couple of points...

1. Up to 100% of females will develop OA int he knee with an ACL rupture. They think it is due to not controlling the rotation motion in the ACLR.

2. The kneecap exists for a reason (i know it hasn't been removed in this case !). Losing that change in vector will make a difference - it just is a matter of time to see what that is...

Good luck with your rehab!
