Unicompartmental Knee System

JOURNEY II Unicompartmental knee system


JOURNEY UNI provides satisfaction to patients by providing minimal bone and ligament removal.

The JOURNEY UNI and PFJ knee systems have been engineered to empower patients with a renewed right to an active lifestyle and seek to bridge the gap of improving patient satisfaction and implant longevity through function, motion, and durability.

Paired with the NAVIO Surgical System, JOURNEY Partial Knee procedures can utilize the benefits of intraoperative planning software and robotic assistance to enable precise implant placement and soft-tissue balance

Femoral component

JOURNEY II UNI femoral component


  • The implant mimics the distal condyle’s normal, anatomic shape by following a 10° A/P angle.


  • The implant comes in seven sizes in order to customize the fit to the patient. 

Bone interface

  • Three planar resections and two peg holes provide a uniform, congruent cement interface.


  • Sizes 3, 4, 5, 6 and 7 all feature the exact same planar resections and peg hole locations. 
  • Sizes 1 and 2 are also interchangeable, with slightly different cuts and peg locations than 3 – 7

Tibial component

JOURNEY II UNI Tibial component image


  • The left medial component can be used on the right lateral tibia, and the right medial component can be used on the left lateral tibia.



  • The implant comes in six sizes, and the poly thickness increases in single millimeter increments from 8 – 11mm to allow for fine-tuning the fit.

* The all-poly version and the metal-backed version have the same instrumentation, allowing for easy intraoperative choice. 


Unconstrained kinematics

  • When coupling a curved femoral component on a flat articular surface, unconstrained kinematics can be achieved.


JOURNEY II UNI Indications

Unicompartmental knee implants are indicated for restoring either compartment of a knee that has been affected by the following:

1. Noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis, oravascular necrosis

2. Correction of functional deformity

3. Revision procedures where other treatments or devices have failed

4. Treatment of fractures that are unmanageable using other techniques.Unicompartmental knee implants are single use only and are intended for implantation only withbone cement.


1. Cases where there is poor bone stock which would make the procedure unjustifiable

2. Active, local infection or previous intra-articular infections

3. Mental or neurologic conditions that tend to pre-empt the patient’s ability or willingness to restrictactivities

4. Neuropathic (Charcot) joint

5.Conditions that tend to place increased loads on implants such as age, weight, and activity level,which are incompatible with a satisfactory long-term result

6.Collateral ligament insufficiency (except in cases where a constrained knee system is indicated and used)

7. Skeletal immaturity.

8. Use of a supracondylar nail through intercondylar notch of PROFIX™ primary femoral components.

9. Use of slotted femoral and tibial stems without adequate bone support.
