In this article we review studies of the near threshold $pp \rightarrow ppK^{+}K^{-}$ reaction done with the COSY-11 and ANKE detectors. We discuss phenomenological studies of the $ppK^{+}K^{-}$ dynamics, in particular the recent investigations on the $K^{+}K^{-} $ final state interaction are presented.
