NexGen LCCK Revision System

Product Description

The NexGen LCCK is intended for patients who, in the surgeon’s judgment, require additional prosthetic stabilization due to inadequate mediolateral, anteroposterior, and varus/valgus ligament function, and require augmentation and/or stem extensions due to inadequate bone stock. For use when both cruciate ligaments are excised and when greater varus/valgus constraint is required (an LCCK Femoral Component can be used with NexGen LPS Articular Surface, however, less varus/valgus constraint is provided). The NexGen LCCK can be used with augments and stem extensions.

Prosthetic Constraint

For patients who lack functional collateral ligaments or whose knees cannot be stabilized by the usual tissue releases, the LCCK features an elevated tibial spine and deeper femoral intercondylar box. A close fit between the spine and box provides stability as the mechanical rollback is induced, inhibiting posterior subluxation and limiting varus/valgus movement to +1.25 degrees and internal/external rotation to +2 degrees. This design accommodates a theoretical range of motion in excess of 120 degrees.

Modular Femoral Tibial Augments

For patients with inadequate bone stock, tibial and femoral augments offer true patient specificity. Tibial: third-, half-, and full-wedge augments or 5-20mm blocks in 5mm increments in Titanium or up to 30mm in Trabecular Metal Material. Femoral: posterior, distal, posterior/distal, and anterior augments. Augments are designed for either screw or cement fixation (anterior augments are cement fixation only), and come available in either Titanium or Trabecular Metal Material.


The Zimmer NexGen LCCK System offers a reported survivorship of 96% at 10+ years when used for revision TKA.1

Interchangeable between all stemmable NexGen Femoral and Tibial Components, straight and offset stem extensions allow the surgeon to optimize canal fill and component positioning.

For patients whose canal is not centered relative to the distal femur or proximal tibial surface, the patented offset design allows the component to be positioned 4.5mm away from the center of the canal in any direction. This flexibility provides for a full 360 degrees of orientation for improved bone coverage, and allows the surgeon to optimize implant position.
