ADVANCE® REVISION

Description

The Advance® Stemmed MP system provides the same joint kinematics in a revision implant as the primary Advance® MP prosthesis, thanks to its ball-in-socket mechanism. The system includes a full range of modular stem extensions, femoral and tibial augments.
Notably, the Advance® Stemmed MP femoral component is boxless, which significantly reduces femoral bone resection.

The positioning of the femoral stem restores natural anatomy, optimizes cortical contact with the anterior cortex, and accurately reconstructs the flexion gap.

The cementless stem extensions have ribs and grooves on their surface for primary mechanical fixation and rotational stability. A coronal slot in the stem reduces dynamic stress to ensure long-term fixation.

Femoral and Tibial Augments

Posterior and distal femoral augments (5 mm and 10 mm thick) can be used independently and are securely fixed to the femoral component of the Advance® Stemmed MP (cemented version) using screws.

Block-shaped (5 mm, 10 mm, and 15 mm thick) and wedge-shaped (15°) tibial augments feature a unique three-point centering mechanism that reduces friction and wear while providing secure fixation on the tibial component.

Wedge-shaped cemented stem extensions are available in three lengths (30 mm, 65 mm, and 100 mm) and in diameters ranging from 10 mm to 18 mm, in 2 mm increments, to precisely match the patient’s anatomy.

Ball-in-Socket Mechanism

The ball-in-socket design of the Advance® Stemmed MP system allows for posterior cruciate ligament (PCL) resection while maintaining anterior-posterior stability, maximizing contact area even in deep flexion, and restoring normal joint kinematics with 15° of rotational freedom around the medial condyle axis.
