We construct nucleon knockout amplitudes which exactly satisfy probability current conservation. The derivation is first produced for a nucleon bound to an inert core and is then generalized to the case of realistic nuclei. Numerical tests are presented for a nucleon bound in a square well potential for which exact results are compared with several approximated ones; the need of imposing probability current conservation is also numerically demonstrated.
