JOURNEY II BCS

Bi-Cruciate Stabilized Knee System

Algemeen

The goal of the JOURNEY II Total Knee System is to enable a higher level of function for total knee replacement patients–to not only relieve pain, but to help them regain their active lifestyles.  Function, motion and durability is achieved through the unique features of the JOURNEY II Total Knee System–anatomic alignment, kinematics and advanced bearings.  Patient outcomes can be directly related to accurate surgical technique and precision instrumentation. The JOURNEY II BCS and JOURNEY II CR instrumentation has been developed to assist surgeons in obtaining accurate and reproducible results and reducing OR time.

This system is designed for use in patients in primary total knee replacement surgery, where the anterior and posterior cruciate ligaments are incompetent and the collateral ligaments remain intact.

 

To replicate normal knee motion, the JOURNEY II BCS and JOURNEY II CR prosthesis provides more mobility in the lateral compartment than other total knee systems 1,2.  For patients that present with significant varus or valgus deformities (> 15º),morbid obesity or deficient collateral ligaments consider whether additional implant constraint is more appropriate. If patients with the above mentioned conditions are scheduled for a JOURNEY II BCS or JOURNEY II CR then assess the flexion space under full ligament tension (eg, laminar spreaders) with the patella reduced and consider having a constrained implant option on hand.

Stability – The patented, proprietary anterior cam supplements the function of the anterior cruciate ligament (ACL) which helps to eliminate mid-flexion instability, a leading cause of early revisions in replaced knees.1-8

Strength – The patented, proprietary anatomic shapes of the femur and tibia promote anatomic positioning and motion post-replacement which has shown to allow less muscle exertion while performing activities of daily living. 5-10

Satisfaction – The chief goal of this system is to provide further improvement to those already achieved with the original JOURNEY BCS design by providing patients the normal patterns of kinematic motion yet to be seen in other systems. 11,12
