The collarless, polished, double-taper design concept used in the CPT Hip System has proven itself clinically in more than 25 years of use.¹ This distinctive design philosophy is based on the use of natural compressive forces to help ensure that the implant is firmly seated and wedged within the cement mantle. The CPT System, in cobalt-chromium² and stainless steel,3,4 has achieved long-term clinical success since its introduction in the early 1990s.
