CENTER VALLEY, Pa.–(BUSINESS
WIRE)–On May 20, 2012, Aesculap Implant Systems’
debuted the new VEGA System Posterior
Stabilized Knee Replacement Technology during the Current Concepts in Joint
Replacement Spring meeting held in Las Vegas, Nevada. The VEGA System is based
on a patent-pending post-cam mechanism that recreates a natural pivotal motion
while greatly reducing surface stress. Additionally, the narrowed design
combined, with smoother transitional radii reduce soft-tissue infringement. 13
femoral sizes and 11 tibial sizes offer a wide-range of options for a better
bone fit. The VEGA System includes
the Advanced Surface
(AS) multi-layer coating, which has demonstrated reduced wear results and
increased longevity. Aesculap Implant Systems
along with an international group of experienced surgeons have collaboratively
combined their expertise and knowledge to design this pivotal breakthrough in
knee replacement technology.
Natural Knee Kinematics
Designed to mimic natural knee kinematics by enabling a physiological pivot
around the medial condyle, the VEGA System’s
distinctive patent pending post-cam design facilitates a large range of motion
and optimized surface contact between the femoral component and gliding
surfaces. The surface contact between the articulating components maximizes
bearing surface stress distribution, reducing the risk of delamination.
Unique 7-Layer AS Coating
Wear is the number one reason for knee revision in the long term.1 The AS multilayer
coating can withstand corrosive environments, high stresses and strains
that all artificial knees are exposed to in the human body. An AS coated knee
prosthesis demonstrates 60% reduction in wear when compared to a CoCr
prosthesis, as demonstrated in testing with other Aesculap knee designs.2,3 The
hard ZrN ceramic surface can lead to improved scratch resistance and good
wettability for better articulation between bearing surfaces.
Soft-Tissue Friendly Design
13 femoral sizes, including standard and narrow design, and 11 tibial sizes,
including standard and AP+ sizes, offer a wide range of soft-tissue-friendly
implants for a better bone fit regardless of gender, size, morphotype, or race.
Additionally, the VEGA System’s
low-profile box helps preserve more bone.
Innovation that Moves You
The VEGA System’s IQ
Instrumentation platform is highly intuitive, with dual-purpose instruments,
fewer trays, and a simplistic design that allows surgeons to operate quickly
and easily resize. Reduce steps in your workflow to save time and money.
The design team was led by William Mihalko, MD, PhD,
Professor and J.R. Hyde Chair and Director of Biomedical Engineering at the
University of Tennessee Campbell Clinic Department of Orthopaedics and
Biomedical Engineering and K.J. Saleh, BSc, MD, MSc (Epid), FRCS(C), MHCM, with
a focus on bringing more natural knee motion with less resistance to patients.
Dr. Mihalko said, “The breakthrough design concepts found in the VEGA System
knee replacement allows the patient to regain their natural motion while the
Intuitive and Quick instrumentation leads you through a logical step-wise
progression during surgery, reducing steps in the Operating Room for optimum
outcomes.”
