Polymotion® Hip Resurfacing
Polymotion® is an advancement to previous generations of HRA with superior novel design features. The PHR® is an evolutionary hip resurfacing system that provides the low wear bearing performance of proven advanced polyethylene components, applying novel bone fixation, negating any of the perceived risks associated with hard-on-hard articulations.
The PHR® System is a single use device intended for hybrid fixation. The femoral head is secured to the ball joint using bone cement, and the acetabular cup is press-fit into the socket with a porous titanium coating for bone on-growth.
The PHR® System consists of:
a femoral head component to resurface the ball of the hip joint
an acetabular cup component to resurface the socket of the hip joint.

Are you the right candidate?
The PHR® System is intended for use in patients requiring primary hip resurfacing arthroplasty due to:
Non-inflammatory arthritis (degenerative joint disease) or dysplasia/developmental dislocation of the hip (DDH), or;
Inflammatory arthritis such as rheumatoid arthritis.
The PHR® System is particularly intended for adults who, due to their relatively younger age or increased activity level, may not be suitable for traditional total hip replacement due to an increased possibility of requiring future hip implants on the same side.
Surgery should be avoided during pregnancy.
There are no tests that demonstrate the device is safe for use in children. The implant should only be used in skeletally mature individuals.
