About


Unity Knee is clinically proven1 with a strong correlation to patient satisfaction2. Soft tissues are balanced to drive knee kinematics using modern surgical principles either manually or with the OMNIBotics™ robotic platform. Unity Knee, developed by a global team of designer surgeons, incorporates implant and instrument designs focusing on MCL isometry and medial joint line preservation to restore the joint function.

Features and benefits

The harmony between the design of Unity Knee implants and instruments creates the stability and satisfaction that every surgeon and patient needs by prioritising medial ligament isometry.

Stability by design

Stability by design


Unity Knee focuses on two main principles:

  • Ligament isometry throughout range of motion by preserving the medial joint line with a single radius femoral design and medial referencing instrumentation.  
  • High rotational freedom on the tibial inserts and optimised sizing to allow patient-specific kinematics.
Personalised alignment

Personalised alignment


Optimising implant positioning for each patient by using the Unity Knee EquiBalance™, which is designed to allow:

  • Ligament balancing in flexion and extension
  • ‘Anatomic’ alignment principles
  • Minimised soft tissue releases in TKR

Versatile

Versatile


Wide variety of implant constraint available from cruciate retaining and condylar stabilised to posterior stabilised. The built-in modularity of the Unity Knee PS femur and tibial tray allows direct compatibility with stems and augments to simplify your difficult primary knee.

Unity Knee instrumentation is available in standard or streamlined sets to suit your specific requirements.

Predictive Balance™


Unity 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 replacement3,4,5.
