OptiStem CRL (Press-fit femoral hip stem)

The OptiStem CRL is a Titanium and Hydroxyapatite (HA) coated press-fit femoral stem. A design that has evolved to define many of the standards for the cementless stems. Identified from several national hip implants registers as having the best long-term outcomes for patients. The geometry provides immediate bone engagement and long-term stability supported by the HA coating that encourages osseointegration, allowing for an anatomic continuity between implant and host bone. 

By basing our design in evidence with well-established features we are able to provide increased access to some of the best-in-class implants, with the highest quality materials.

Design Features

  • Clinical Heritage – modelled after the implants with the highest survivorship, reducing costs while simultaneously improving patient outcomes. 
  • HA coating – providing an optimal surface for biological fixation.
  • Stability and Load transfer features- both Horizontal and Vertical grooves are present to provide increased stability and proximal load transfer helping to minimise distal thigh pain.
  • Neck allows for a wide degree of movement before impingement.
  • A surgical approach that is bone sparring.

Product Options

  • Collarless and Collared
  • Standard offset with 10 sizes
  • Lateral offset with 11 sizes
