  Using the unification of the chiral SU(3) model and QCD sum rules, we deduce
the in-medium properties of $K^\pm_1$ meson. Within the chiral SU(3) model,
medium modified gluon and quark condensates are evaluated through their
interactions with the scalar fields ($\sigma$, $\zeta$, $\delta$, and $\chi$).
These condensates are further used as input in the Borel transformed equations
of QCD sum rules to evaluate the in-medium mass of strange $K^\pm_1$ meson. The
in-medium property of the above meson can be used to study the restoration of
chiral symmetry in nuclear matter.
