Unity Knee™ with EquiBalance™ was launched today at the American Academy of Orthopedic Surgeons (AAOS) 2018 Annual meeting by the CorinGroup.  The instrumentation is designed to facilitate ligament balancing and soft tissue preservation during total knee replacement.

The company reports while conventional instruments used in knee replacement may alter the natural joint line, the Unity Knee with EquiBalance preserves the joint line to help enable ligament balancing and medial collateral ligament (MCL) isometry, effectively achieving functional positioning of the knee. This may improve implant stability and performance, and reduce pain and discomfort after knee replacement.

“The new knee system minimizes the impact on soft tissue and enables maintenance of both the distal and posterior medial joint line throughout the range of motion, which may result in improved patient function and joint stability,” said orthopaedic surgeon Stefan Kreuzer, MD of INOV8 Orthopedics in Houston, TX.* “Everybody’s knee is different and what may be natural alignment for one may be different for another. The Unity Knee with EquiBalance lets surgeons make adjustments based on specific patient anatomy and movement,” said Dr. Kreuzer.

“Corin continues to embrace and advance the science and practice of personalization and functional positioning in joint replacement with meaningful and evidence-based innovation that respects the individual differences in patient anatomy and movement,” said Paul Berman, President, Corin USA.
