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, or avascular necrosis;

2. Correction of functional deformity;3. Revision procedures where other treatments or devices have failed; and4. Treatment of fractures that are unmanageable using other techniques.

Unicompartmental knee implants are single use only and are intended for implantation only with bone cement.

Contraindications:

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

restrict activities.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.

JOURNEY™ II UNI Unicompartmental Knee System Femoral component

Asymmetric: The implant mimics the distal condyle’s normal, anatomic shape by following a 10° A/P angle. This allows the left medial component to be used on the right lateral condyle, and the right medial component to be used on the left lateral condyle.

Anatomic: The implant comes in seven sizes in order to customize the fit to the patient. The shape of the sagittal J-curve is the result of extensive testing to optimize function throughout the flexion arc. The anatomic anterior mesial bevel is a design feature that further optimizes the shape by ensuring smooth patellar tracking in deep flexion.

Bone interface: Three planar resections and two peg holes provide a uniform, congruent cement interface. The pegs significantly diverge from the posterior planar resection, and the posterior peg is long enough to aid in placing the component in small spaces for final implantation. The entire mating surface, including the pegs, is grit-blasted to enhance cement fixation.

Versatility: Sizes 3, 4, 5, 6 and 7 all feature the exact same planar resections and peg hole locations. Once these preparations have been made, the 3 – 7 trials are interchangeable, and can be up- and down-sized until a decision is made for the final implant choice. Sizes 1 and 2 are also interchangeable, with slightly different cuts and peg locations than 3 – 7. Sizes 3 – 7 typically are used for 80% or more of uni cases.

Tibial component

Asymmetric: 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.

Flexibility: 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. The all-poly version also has a thin 7mm option.

GENESIS™ UNI Kinematics: JOURNEY II UNI features the same proven tibia articular as GENESIS UNI/ACCURIS™. This gentle conformity gives similar interchangeability and kinematics as a round on flat design with increased contact area to lower point stresses. The lack of constraint allows JOURNEY II UNI to be ACL/PCL conserving, allowing the native ligaments to control the movement of the knee.

JOURNEY™ II UNI Unicompartmental Knee System Traditional Method continued

Step 1: Initial EM Guide set up continued

• Refine resection depth with Tibia Stylus (2mm, 4mm, 6mm or 8mm)

• Tibia stylus references cutting surface on either 5° Captured Block or any Uncaptured block (0°, 5°, or 7°).

Using the tibial styli

• Some surgeons prefer to place the resection check in the cutting slot to locate the transverse tibia resection.

• If it is preferred to use a stylus in order to measure the resection, two double-sided styli are offered to measure 2, 4, 6 or 8 millimeters of resection.

• Evaluation of deformity during preoperative planning may aid in determining which stylus to use.

Step 2: Resect Proximal Tibia

• Additional resection may be taken using either block by unlocking adjustment screw on EM Guide and dialing down desired amount.

Note: Lines on EM Guide are 2mm apart.

• If initial resection is made with 5º captured block, 5º uncaptured block may be used as +2mm additional resection block without unlocking alignment guide.

• Two oblique pin holes provided for optional additional fixation

Step 3: Assess joint balance

• With measured resection balancing technique a set of two piece gap sticks are used to assess imbalance caused by deformity.

• This technique is a posterior referencing technique where the distal resection is adjusted based on deformity.

• Insert thickness/flexion gap is established by increasing the thickness of outer rail in flexion.

• Extension imbalance is determined by increasing thickness of inner shim.

1. Determine f lexion gap by inserting outer colored rails increasing in thickness with inner Black Shim Number “0”.

2. Once Flexion gap is established continue to use the Colored Outer Shim which best approximated the flexion gap, bring the knee into full extension and assess the extension gap.

• If laxity is found increase the thickness of the Inner (Black) Shim until the desired extension gap is found.

• The combination of colored rail from Step 1, and appropriate numbered Black shim will represent your extension gap.

• If extension gap is tighter than flexion gap, go to steps 3A and 4A (page 13). Do not go to step 4, page 12.

Traditional Method continued

Step 4: Resect Distal Femur

• The numbered inner shim is then replaced with the like numbered distal cutting block.

Reminder: If extension gap is tighter than flexion gap, go to steps 3A and 4A (page 13). Do not go to step 4, page 12.

• Once the Distal block is pinned into place (two parallel pins and optional oblique pin) the outer rail may be removed to allow distal resection to be made with knee in any flexion angle.

• Numbered blocks will resect number listed in millimeters less than the distal implant thickness to re-establish a balanced postoperative condition.

Step 3A: Assess joint balance continued

2a. If extension gap is found to be tighter than flexion gap, decrease the outer rail thickness and continue to use Number “0” black shim. The number of rails decreased between the rail used in flexion and extension will be the amount of additional resection needed.

Reminder: If extension gap is looser than flexion gap do not complete Steps 3A and 4A, return to Step 4 (page 12).

Note: Colored Rail used to establish flexion space will continue to represent flexion gap

Step 4A: Resect Distal Femur

• Using the same colored shim that gave the final extension balance; replace the Number “0” Black Shim with the Number “0” Distal Cutting Block.

• Affix two pins through the parallel guide holes (non-oblique) in the distal cutting block as shown, then replace the Number “0” Distal Block and Gap Spacer Rail with the Femur Recut Block using the holes marked with the appropriate resection depth.

• Resect the distal femur.

Step 5: Assess joint balance

1. Balance is established by first determining flexion gap using Colored Gap Balancing Rails and Number “0” Black Insert.

2. Once flexion gap is determined extension gap will be determined by using Colored Gap Balancing Rails and “Resected Gap Check” Black Insert.

• After both flexion and extension gaps have been assessed the thicker colored rail will determine the desired insert thickness.

• If the thinnest rail (7mm for All Poly/8mm for Metal Backed) will not fit in either joint space with the appropriate Black Insert additional Tibia resection will be necessary.

Install implants

Tip: If the resected surfaces of the tibia and/or femur are sclerotic, drill multiple holes with a small drill (2.0mm – 3.2mm) to improve cement intrusion.

Tibia Component

• To facilitate insertion, flex the knee and externally rotate tibia.

• Apply Cement and press the tibia baseplate onto the tibia,

• Press down on the posterior portion of the tibia component first to force the cement anterior, then press down on the anterior portion of the component.

• Use the Tibia Impactor to fully seat the tibia baseplate.

• If sterile gauze was used, remove it slowly from behind the tibia and use a Cement Removal tool to remove any excess cement.

Femoral Component

• Apply cement and seat the femoral component with the femoral lugs aligned with the pre-drilled holes.

• Use the Femoral Impactor to fully seat the component.

• After the cement has cured, remove any excess cement before final placement of the tibia articular surface.

Tip: Tibia trial may also be used while cement is drying before final selection and implantation of tibia articular surface.
