About


Designed with three specific criteria in mind, Apex Knee addresses stability to improve function, while providing optimal fit, and fixation to promote long term survivorship. These design principles have created a knee replacement system well suited for today's active patients, by combining the best of modern knee replacement philosophies with innovative delivery technologies such as robotics.

Introducing the APEX Knee system: a design focused on function, fit and system versatility, which enables the surgeon to match the specific needs of each patient.

Function and stability

Function and stability


Matching insert conformity to the femur enhances the functional characteristics of the knee and optimises stability throughout range of motion1.

Fit

Fit


Narrow size femur options across the range of sizes to provide best bone coverage.

  • Femoral component overhang of >3mm doubles the odds of knee pain at two years after TKR2.

Asymmetric tibial design based on anthropometric data to match the patient's native anatomy.

  • Matching tibio-femoral rotation improves patella tracking3.
  • Minimises tibial overhang and soft tissue irritation.
Versatile

Versatile


A full range of implant solutions with varying levels of insert constraint in both CR and PS femoral designs, with cemented and porous coated fixation. Modular stem and augment options also available to address more complex clinical scenarios.

Apex Knee TiN

Apex Knee TiN


The latest addition to the Apex Knee range includes a proprietary coating technology, which provides a dense, thin and uniform ceramic coating, designed to limit metal ion release and improve implant scratch resistance and wear properties4.

 

Predictive Balance™

Predictive Balance™


The Apex Knee is available with OMNIBotics™ robotic-assisted technology, providing predictive gap balancing throughout range of motion. Advanced femoral planning optimises gaps and implant position which has been shown to improve intraoperative accuracy, reduce soft tissue releases and improve postoperative patient satisfaction at 12 months compared to conventional knee replacement5,6,7.
