COMPETITIVE COMPARISON CORAIL® AMT TOTAL HIP SYSTEM VS. SMITH & NEPHEW POLAR CEMENTLESS STEM CORAIL HIP SYSTEM OVERVIEW First implanted in 1986 by the ARTRO Group in France, published evidence for the CORAIL Hip System proves that it is a class-leading hydroxyapatite (HA) coated cementless implant. In many markets it is considered the standard of care for primary total hip arthroplasty (THA) when compared with other cementless hip implants.1-3 The CORAIL Stem is designed to provide secure initial and long-term fixation with mechanical stability within the femur. This is achieved by a combination of shape, surface features, implant material and choice of biological material. Due to the success of CORAIL its Portfolio has continued to expand; allowing it to meet the needs of patients and surgeons in revision and to treat patients with poor bone stock with the development of CORAIL Revision, distally locking REEF™ and CORAIL cemented.
