So, there will still be some issues with knee.
Not disagreeing with you as such, just pointing out that the knee should be 100% healed at this point. What's left is reduced proprioception (the body's ability to sense it's position), balance, muscle strength and flexibility.
Strength is something you can't really start working on until the knee is healed (until the bone forms around the grafted ligaments, securing the in place). That takes about 6 months and there's not a damned thing you can do to speed up the process. Flexibility is hard to work on as well, but it's something that newer surgical procedures have done a lot to improve.
Proprioception is the real killer. This can manifest itself in any number of ways, including "favoring a leg". The fundamental problem is that "the body" doesn't have a firm grasp of exactly how bent / twisted the knee is in a given situation and therefore cannot "tighten up" to prevent significant (re)injury. It's natural to overcompensate for this and rely on your conscious mind to tell the body to react. That takes way too long though, and significantly impacts performance.
Even with the best rehab available today, regaining proprioception takes a really long time - sometimes years, sometimes it never fully recovers.
