Efficiency
Time
Is there anything more valuable? Shorten procedures by eliminating sizing and alignment surgical steps with patient matched instrumentation. Improve productivity with reduced instrumentation, requiring less set-up and turnover time.
Size
Want the confidence of walking into the OR knowing the size of the implant that will be used? With VISIONAIRE patient matched cutting blocks, precise sizing is determined pre-operatively using both MRI and X-Ray analysis.
Position
This technology achieves accurate rotational and A-P position. All of the commonly-referred anatomical landmarks (AP axis, epicondylar axis) are analysed pre-operatively, allowing for the proper positioning of the implant for each individual.
Precision
Proven alignment methodology
Unlike other cutting blocks that use alternate methods of alignment, VISIONAIRE blocks are aligned to the mechanical axis of the knee, the gold standard. Without this orientation to the mechanical axis, components may not achieve optimal performance.
Research shows that malalignment can lead to early failures
- A tibial component with more than 3.0° of varus had increased odds of failure.
- Components placed in varus alignment have a higher rate of loosening and revision when compared with components placed in neutral alignment.
- With VISIONAIRE Patient Matched Instrumentation, surgeons can be reassured that they are implanting components in accordance with the proven standards of total knee arthroplasty.
Success
Success is built in
VISIONAIRE Patient Matched cutting blocks are made from medical grade nylon and are delivered with the size, patient name, left or right knee and implant system clearly labeled. Sterile packed with the option to be flashed, the cutting block matches standard instrumentation for intraoperative changes
Implant choice
Some companies with this technology only allow for the use of cruciate-retaining implants or limit options to a single system. VISIONAIRE Patient Matched Instrumentation is available for Smith & Nephew JOURNEY BCS Bi-Cruciate Stabilized Knee System, GENESIS II Total Knee System and LEGION PRIMARY Total Knee System in cruciate retaining and posterior stabilized options.*
*CR implants not available for JOURNEY BCS
Surgeon Control
VISIONAIRE Patient Matched Instrumentation is intended to enhance the surgeon OR experience, not to limit the surgeon's decision-making or flexibility. Changes can be made to the preop plan prior to surgery. Intraoperative flexibility is designed into each cutting block, so standard instrumentation can be utilised in the event that bone resection modifications are needed, such as additional distal resection to accommodate for a flexion contracture.
