Breaking the Revision Cycle

The Zimmer Biomet Trabecular Metal Acetabular Revision System (TMARS) combines clinically proven Trabecular Metal Technology1–3 with the ability to tailor individualized solutions for each patient. From simple to complex revision arthroplasty, this combination sets the standards for acetabular reconstruction.

System Features

The TMARS system consists of the following acetabular and auxiliary implant designs:

Trabecular Metal Revision Shells and Liners

Designed for use in revision and primary cases. A one-piece construct, created by cementing the liner into the shell, eliminates concerns about backside wear. The low modulus of elasticity of the Trabecular Metal material can produce more normal physiological loading and reduce stress shielding.5

Trabecular Metal Cup Cage

Used in conjunction with the Trabecular Metal Revision Shell to provide adequate stability by spanning acetabular defects and pelvic discontinuities to provide initial mechanical stability of the Cup-Cage construct until biological fixation occurs. Cementing the Longevity Highly Crosslinked Polyethylene Liners, Cages, and Trabecular Metal Revision Shells together creates a single construct, without concerns of micromotion.6

Trabecular Metal Buttress and Shims

  • Work with the revision shell to address extensive superior segmental defects (Paprosky Type IIIA).
  • Serves as an alternative to allograft, without potential for bone resorption or disease transmission.
  • Creates a monolithic construct without concerns for micromotion by using cemented interfaces.6
  • Conserves host bone while implant size, position, and orientation are determined by the defect. 

Trabecular Metal Augments and Restrictors

The Trabecular Metal Acetabular Augments and Restrictors fill bone deficiencies as an alternative to preparing and using structural grafts.7




  • Proven technology and fixation

Addresses Range of Deformities

  • Designed to fit Paprosky Type I to IV acetabular deformities, enabling an algorithmic approach to challenging revisions.

Lower Infection Rates

  • Trabecular Metal (TM) acetabular components used in revision THA are associated with decreased rates of re-revision for infection compared to non-TM components as reported by Tokarski et al.10
