JOURNEY II BCS

Product Info

The goal of the JOURNEY II Bi-Cruciate Stabilised (BCS) 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. Unmatched function, motion and durability is achieved through the unique features of the JOURNEY II BCS system–anatomic alignment, kinematics and advanced bearings.

Function:

Stability – Provides a proper femoro-tibial A/P position yielding a virtual elimination of paradoxical motion, anterior sliding of the femur during flexion.1-8

Strength – Restoration of both the anatomic A/P alignment and the normal kinematic patterns of the knee should produce more normal neuromuscular firing patterns throughout the range of motion as demonstrated in the original BCS design.5-10

Satisfaction – Restoration of more normal neuromuscular firing patterns throughout the range of motion should improve a patient’s ability to perform the activities they are demanding as demonstrated in the original BCS design.11,12

Indications for JOURNEY II BCS

  • rheumatoid arthritis
  • post-traumatic arthritis
  • osteoarthritis
  • degenerative arthritis
  • failed osteotomies or unicompartmental replacement.

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 prosthesis provides more mobility in the lateral compartment than other total knee systems. 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 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.
