Heightened realism is obviously at the forefront of Nolan's Batman movies so this would translate into a real man fighting crime for this long. Everyone saw the damage he had suffered in TDKR from just the limited he was Batman and that was before the events of TDKR!
I agree with this, you just cannot physically do what Batman does night in and out without incurring some serious damage. Also, even though he wasn't active in those 8 years, cartilage does not grow back, once you start damaging and losing it...it only deteriorates.
