It depends on the extent of nerve damage
incurred. If there is a laceration of the nerve but the lacerated segment is short and the ends can be brought together without tension and attached, then there is a good prospect of recovery of sensations and motor functions provided the nerve coaptation is done in a proper fashion. If a longer segment of nerve has been involved or if the nerve has been damaged at many places then nerve grafts taken from other parts of your body like the leg have to be used and the return of sensations and muscle function would be less than optimal. Similar thing applies to more than one nerve damage.
