ORTHOPAEDICS

JOURNEY◊ II XR◊ Bi-Cruciate Retaining Knee System

While JOURNEY II TKA has been shown to restore anatomical shape, position and motion,1-4 the JOURNEY II XR system goes a step further by allowing the ACL to be retained. An anatomical design is intended to help a smoother recovery, improved function and higher patient satisfaction*1-11

Learning from the past to innovate for the future

Bi-cruciate retaining (BCR) knees have been designed since the very early days of orthopaedics. Even in those early days, surgeons and manufacturers recognised the importance of ACL function to kinematics, proprioception and stability.

The JOURNEY II XR System is designed with the knowledge and learnings of past BCR knee designs, while improving upon early concepts through the principles of anatomic knee design,1-5 improved instrumentation and technique, and advanced bearing materials.
