Inelastic collision assumes maximum loss of cinetic energy (deformation, heat, etc) since they glue together.
When you decide that they stick together you lose one degree of liberty so you don't need the energy equation anymore, the system is already defined.
Perfect elastic collision assumes conservation of energy.
