We present the result of a full direct component
calculation for the planar four-loop anomalous dimension
of the Konishi operator in Supersymmetric Yang-Mills theory.
Our result confirms the results obtained from superfield and superstring
computations, which take into account finite size corrections to the
all-loop asymptotic Bethe ansatz for the integrable models describing the
spectrum of the anomalous dimensions of the gauge-invariant operators and the
spectrum of the
string states in the framework of the gauge/string duality.
