Vanguard® Knee

Surgical Simplicity

Vanguard

The Vanguard® Knee System offers surgical simplicity to knee arthroplasty with its bearing versatility and complete component interchangeability. The independent fit of the femoral, tibial, and patella components allow surgeons to provide tailored patient care. The Vanguard Knee System offers an entire spectrum of knee stability, including:  

  • 2 femoral stabilisation options: cruciate retaining (CR) and posterior stabilised (PS) 
  • 10 femoral sizes
  • 9 tibial sizes
  • 5 levels of bearing constraint
  • Complete interchangeability between femoral and tibial components
  • Optimal congruency in the coronal plane resulting from Zimmer Biomet's proprietary 1:1 conformity
  • 26 patella options in multiple diameters, thicknesses, and peg configurations
  • 3 fully interchangeable instrument platforms

Part of the surgical simplicity is the overall performance surgeons and their patients can rely on with Zimmer Biomet orthopaedic implants.

Zimmer Biomet’s Vanguard Knee System features 2 knee implant options so that surgeons may select an implant specifically suited to each patient’s unique needs. Additionally, 3 fully interchangeable instrument platforms allow for various approaches, ranging from traditional to minimally invasive quadriceps sparing.  

Product Features

Cruciate Retaining (CR) Knee:

Posterior Stabilised (PS) Knee:
  • Proximally flared patella track accommodates varying Q-angles
  • Extended trochlear groove maintains patella contact in flexion
  • Rounded sagittal profile reduces soft tissue forces mid-flexion
  • 10 proportional femoral sizes
  • 1:1 tibial-femoral coronal articulation provides increased contact area
  • Enhanced cement grooves
  • PPS® Porous Plasma Spray coating for cementless application; Interlok® finish for cemented
  • Proximally flared patella track accommodates varying Q-angles
  • Extended trochlear groove maintains patella contact in flexion
  • Conservative proportional box resection preserves femoral bone
  • Extended cam increases dislocation height
  • Posterior condyle design accommodates up to 145º flexion in primary cuts
  • Accommodates distal and posterior augment options
  • PPS Porous Plasma Spray coating for cementless application; Interlok finish for cemented

3 bearing options:

  • CR –  3º posterior slope
  • CR Lipped – enhanced posterior lip
  • Anterior Stabilised – ultracongruent deep dish design

2 bearing options:

  • PS – substitutes for PCL – no constraint
  • PS+ - rotational and varus/valgus constraint

Technology

Vanguard with  VERASENSE™

VERASENSETM quantifies soft-tissue instability, tibial-femoral rotation, and alignment in total knee arthroplasty. Adding to the Vanguard Knee System, the VERASENSE surgical solution from OrthoSensor® is a single-use, wireless sensor that takes the place of standard tibial insert trials and provides surgeons with dynamic intra-operative feedback without interrupting their workflow.

  1. Rotate: Establish congruent tibial-femoral contact point rotation1,2,3
  2. Balance: Dynamically fine tune soft tissue balance through full range of motion1,2,3
  3. Align: Confirm alignment values such as proximal tibial varus/valgus, and overall hip-knee-ankle mechanical axis
  4. Provides Options to Enhance Intra-operative Performance: Available in a variety of tray sizes, thickness, and articulation to address many soft tissue scenarios:
    1. Articulations: cruciate retaining and posterior stabilised
    2. Thickness: 10-18mm
    3. Tray Sizing: 6 sizes
