CORAIL® Revision – the Conservative Option

The Orthopaedic Patient Population is Changing

Prof Tim Board at the Wrightington (UK) Hospital Orthopaedic Centre of Excellence, has reported that 26% of hip revision patients between 2006 and 2016 were under the age of 60 and 57% were under 70 years of age.

26% of revision patients are under the age of 601

57% revision patients are under the age of 701

Type I

Type II


89% of Hip Revisions are Type I, II or IIIA (Paprosky classification) and are suitable for conservative revision treatment with the CORAIL Primary or Revision System.2

By selecting CORAIL Revision as a conservative option, you may be able to preserve healthy bone for future use.

The CORAIL Revision stem maintains the same low-profile proximal intramedullary geometry as the CORAIL Primary stem. The longer distal portion of the stem incorporates slots designed to provide adaptability to the natural curve of the femur and may help prevent thigh pain.


Based on the CORAIL and KAR™ Hip Systems’ clinical history, the CORAIL Revision Hip System is a taper wedge revision stem designed to provide a bone-conserving option compared to modular revision systems.3

Designed to offer a simplistic technique and efficient instruments, the CORAIL Revision Hip System is designed to provide the science of simplicity for today’s revision scenarios as well as primary patients.

Reliable Results

“A fully HA-coated stem in femoral revision surgery can provide reliable results for up to 27 years.”4

“The bone changes confirmed a well-fixed femoral component with a rather physiological transfer of stress from proximal to distal regions with
 no significant thigh pain.”4

Restoring Biomechanics

In Revision Total Hip Replacement, biomechanical challenges confront the surgeon in restoring the normal mechanics of the hip joint while achieving stable, long-term fixation of the prosthetic components in host bone. Restoration of femoral off-set, global off-set and leg length is a key objective in Hip Revision Surgery.

“Aiming to achieve fixation as proximal as possible and as distal as necessary allows a conservative approach to revision surgery”3

“Confidence can be taken in restoring adequate biomechanics of the hip in revision surgery using a
non-modular stem”3

“Restoration of biomechanics achieved in 84-97% of cases.”3

“Results compare favorably with studies using a modular, Wagner type prosthesis.”3
