Libertas® Acetabular Cup

Compatible with CoCr and Biolox® modular femoral heads

The Libertas Acetabular Cup is a cementless component used in total hip replacement surgeries. It is designed for a secure press-fit implantation into the acetabulum and is compatible with highly cross-linked ultrahigh molecular weight polyethylene liners. Screws can be added when additional fixation is required.

Libertas Acetabular Cup is Designed for Optimal Fixation

The cup is designed to be implanted into the acetabulum with a tight fit just below the equator of the shell. The shell is oversized by 1.3 mm in relation to the reamed bone cavity. Preoperative templating using X-rays and CT scans in the case of unusual conditions in the acetabular roof further helps plan the surgery for optimal fit and fixation.

The Libertas Acetabular Cup features:

  • Mechanical Stability – Press Fit Philosophy, Design Geometry, and Optional Screw Fixation
  • Biological Stability – Ti-Growth® Coating
  • Bone Conservation – 16 Shell sizes for better fit with matched odd and even sized acetabular reamers
  • Congruent Stress Transfer – Overall Design Geometry/corresponding modular shells with CoCr or Biolox® delta head choices (with offset options)
Advanced Materials and Coatings

The Libertas Acetabular Cup shell is manufactured in Titanium alloy (Ti6Al4V-ELI) with an external Ti-Growth® Titanium plasma spray coating. The exterior shell surface has been designed to pre-stress the bone in the oversized area specifically to prevent unwanted preferential apical loading. The shell accepts highly cross-linked ultrahigh molecular weight polyethylene liners, which can accommodate a range of Biolox® Delta Ceramic or cobalt chrome heads of different sizes, lengths, and offsets.
