Features and Benefits of JOURNEY II Total Knee Arthroplasty - Rediscover normal

 

  • Smoother recovery
  • Improved function
  • Higher patient satisfaction

 

Smoother recovery

JOURNEY II TKA has been demonstrated to significantly improve flexion by enabling 23º range of motion improvement earlier in the recovery period.3

JOURNEY II TKA smoother recovery

Improved function

The normal knee designs of JOURNEY II TKA have shown to deliver improvements in both knee function and motion with increased medial/lateral (M/L) stability mid-flexion.4-6

JOURNEY II TKA improved function

Higher patient satisfaction

Quicker recovery, improved function and normal kinematic patterns of motion lead to high levels of patient satisfaction.3-5

JOURNEY II TKA higher patient satisfaction

Defining Normal

Defining normal

Advanced technology should lead to extraordinary outcomes. Using cutting edge computer simulation, JOURNEY II TKA is designed to restore the function of the normal knee; replicating anatomic shape, position and motion resulting in higher patient satisfaction.1

The JOURNEY II TKA has been designed to do what no other total knee replacement currently does, restore normal position, shapes and motion.2-5

Normal shape

Accurate replication of anatomic, asymmetric femoral profile

JOURNEY II TKA normal shape

Medial concavity and lateral convexity of the tibial geometries restored

JOURNEY II TKA normal shape medial concavity

Normal position

The JOURNEY II knee is designed with an anterior tibial sulcus to restore the native knee’s normal starting AP position, preventing paradoxical motion.

 

JOURNEY II TKA normal position

The JOURNEY II knee is designed with an anterior dwell point and 3° varus jointline which restores the natural patellar tendon angle and improves patella track.

JOURNEY II TKA normal position patella track

Normal motion

Full extension: 0º

The anatomic position in full extension reduces paradoxical motion in the early gait cycle

JOURNEY II TKA Normal Motion full extension

Mid-flexion: 1-90º

Concave medial tibial plateau provides anatomic stability while proprietary convex lateral plateau drives external rotation

Asymmetrical posterior cam promotes femoral external rotation and aligns anatomic patella femoral angle

JOURNEY II TKA Normal Motion mid flexion

Deep-flexion: 90+º

External rotation is maximized to reduce stress in the knee

Mimicking the normal knee, JOURNEY II TKA translates bilaterally posteriorly with lateral plateau relief to maximize deep flexion6

JOURNEY II TKA Normal Motion deep flexion

Bi‑cruciate stabilized total knee arthroplasty can reduce the risk of knee instability associated with posterior tibial slope

The purpose of this study was to evaluate the relationship between posterior tibial slope and knee kinematics in bi-cruciate stabilized (BCS) total knee arthroplasty (TKA), which has not been previously reported.

In Vivo Kinematics after a Cruciate-substituting TKA

The primary goal of our study therefore was to describe the in vivo kinematics after implantation of a TKA prosthesis based on a guided-motion principle. Patterns of motion in the native knee show substantial variability. Guided motion prosthetic designs offer stability but may limit natural variability. To assess these limits, we therefore determined the in vivo kinematic patterns for patients having a cruciate-substituting TKA of one design and determined the intersurgeon variability associated with a guided-motion prosthetic design.

In Vivo Kinematic Comparison of a Bicruciate Stabilized Total Knee Arthroplasty and the Normal Knee Using Fluoroscopy

The bicruciate stabilized (BCS) total knee arthroplasty (TKA) features asymmetrical bearing geometry and dual substitution for the anterior cruciate ligament and posterior cruciate ligament (PCL). Previous TKA designs have not fully replicated normal knee motion, and they are characterized by lower magnitudes of overall rollback and axial rotation than the normal knee.
