If my hand is penetrated by a knife, just like those in movies, can it fully recovered and function like it always did?

Depends what it hits on the way. If a major nerve gets sliced it can take quite a while to recover, and may never recover fully. If a tendon gets sliced, it's up to having a good surgeon to re-connect it. Again, full function may be recovered, but may not depending on how badly mangled things are and how good a job the surgeon does. Similar things can happen if muscle bundles are fully or largely severed. Severed ligaments, same thing, though the actual change experienced for severed ligaments could vary widely depending on exactly which are severed.

Edit: "...can it fully recover and function like it always did?" is fine.

Edit 2: If nothing like that is hit (which is entirely possible) the hand could not only recover full function, but could continue to function immediately if the knife were removed (though with pain, blood loss, and risk of further injury, naturally).
