The ${K}^{+}$-nucleon elastic scattering process has been reexamined in light of recent measurements which have found a narrow exotic $S=+1$ resonance in their $KN$ invariant mass distributions. We have analyzed the existing database in order to consider the effect of a narrow state on fits to ${K}^{+}$-nucleon observables.
