While some studies suggest that a UKA can be used in the presence of patellofemoral disease, there is the risk of patellofemoral pain and early failure. One study has noted that daily activities such as stair climbing and chair rise are affected by patellofemoral pain and degeneration.⁵  The JOURNEY^◊ DEUCE^◊ system allows surgeons to offer a comprehensive treatment solution to patients with bi-compartmental disease that is a less invasive procedure than a TKA.

Like a UKA, the JOURNEY^◊ DEUCE^◊ Bi-Compartmental Knee System preserves the ACL and does not require medial, lateral or posterior releases, allowing for normal proprioception to be retained.

The JOURNEY^◊ DEUCE^◊ system removes approximately 50% less bone⁶ than a TKA by leaving the lateral compartment intact, maintaining bone stock and the anatomic joint line.

The JOURNEY^◊ DEUCE^◊ system can be implanted using a minimally invasive approach if desired, and patients’ recovery should resemble a UKA, with less blood loss and pain.⁷

The JOURNEY^◊ DEUCE^◊ system with an OXINIUM^◊ Oxidized Zirconium femoral component is an ideal choice for younger or more active patients. However, as the benefits of less bone and tissue resection also are advantageous to older patients and those who may not require the wear reduction capability of OXINIUM^◊ technology, the JOURNEY^◊ DEUCE^◊ femoral component is also available in CoCr to allow for complete demand matching.

The JOURNEY^◊ DEUCE^◊ Knee System works with the GENESIS^◊ II SPC Total Knee System, as it shares the same A-P box cuts and proven lateralized trochlear groove for optimized patellar tracking.⁸ Postop revisions have the potential to be revised to a primary total knee replacement.
