Replacement Knee System Conserves Bone and Ligament

An innovative knee system may give nearly 70% of all patients receiving a total knee replacement a more minimally invasive, bone and ligament preserving treatment alternative.

The Journey Deuce bi-compartmental knee system replaces the medial tibiofemoral compartment and patellofemoral compartment with a single femoral component. The lateral tibiofemoral compartment is left untouched. The deuce implant retains both the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL), allowing more normal kinematics throughout the range of motion (retention of the ACL and PCL has been shown to maintain patient proprioception). A range of six femoral and tibial sizes has been designed for optimum fit and to accommodate both men and women. The system is available in Oxinium (oxidized zirconium), a patented bearing surface that has been shown to reduce wear up to 85%, thereby potentially increasing the longevity of the implant. The Journey Deuce is a product of Smith & Nephew (Memphis, TN, USA).

"With the retention of the anterior and posterior cruciate ligaments, the Journey Deuce knee system addresses an unmet need in the market for the active, informed patient who may be concerned about potential reduced knee function and mobility with a total knee,” said Joseph DeVivo, president of Smith & Nephew orthopaedic reconstruction. "The Journey Deuce knee system provides a bone-conserving alternative to a total knee replacement, while allowing for earlier intervention and preserving all future surgery options for patients, including a total knee replacement.”

Oxinium is an advanced bearing product technology that transforms the surface of the implant to a ceramic, resulting in a material that incorporates the best features of ceramic and metal while avoiding the limitations associated with either material.
