  In the present paper we review the $q$-analogue of the Quantum Theory of
Angular Momentum based on the $q$-algebra $su_q(2)$, with a special emphasis on
the representation of the Clebsch-Gordan coefficients in terms of
$q$-hypergeometric series. This representation allows us to obtain several
known properties of the Clebsch-Gordan coefficients in an unified and simple
way.
