Novation Crown Cup

The Novation® Crown Cup® is a titanium hemispherical design that utilizes Connexion GXL® polyethylene liners, which minimize wear debris over standard polyethylene.

With a goal of creating a more stable hip replacement in mind, the Novation Crown Cup uses a sizing scheme that allows the largest head possible while maximizing polyethylene thickness.

Features and Benefits

Reliable

  • Three-facet locking mechanism
    • Anti-rotational tabs secure the liner firmly, providing enhanced stability
    • Full congruency between the shell and liner inhibits micromotion and maintains liner integrity under load and stress
    • Locking mechanism resists transverse and tipping forces and minimizes micromotion by providing a secure point of stabilization

Versatile

  • Wide range of acetabular options enable patient-anatomy matching, initial stability to promote biologic fixation, and restoration of kinematics.

Intuitive

  • Unique, non-threaded mechanism for easy on/off attachment to acetabular shell
