Being Batman is a physically demanding job, Bruce Wayne had been shot, beaten, set on fire, gassed by weaponized hallucinogens, fallen from extreme heights, bitten by dogs, survived explosions, crashes, etc.. While the Batsuit would offer him some protection, the physical trauma he had sustained would certainly take its toll on his body. As we see at the beginning of The Dark Knight, Bruce had several scars over his body and he had only been Batman for less than a year. In this film, 8 years have passed and Bruce has been locked away in seclusion. If he didn't stay in top shape, the previous trauma to his body would likely start taking their toll. At the end of The Dark Knight, Bruce can be seen limping after falling while running from the police, so the cane is probably a result of the fall.
