Horn,
I had Anteria & Posterial & Medial ligaments removed! + the top of the leg bone came off in the process and had to be glued/sewn back on!(Footballing injury - Hyperextended - It Hurt like hell!)
I hadn't taken up flying at the time, but 6 months after my accident went to get my PPL with a view to going commercial and my Class 1 - Basically I had to push the AME off of the end of the couch with my feet, to simulate fully rudder deflection...So I don't think you will have any problems.
