8. Johnson & Johnson – DePuy Synthes: Attune knee systemThe Attune knee system is a total knee reconstruction system that has a high level of stability and motion. It features technologies from DePuy Synthes to help patients regain full movement in their knees, according to the company. It uses Attune Gradius Curve to reduce femoral radius and give a smooth transition from stability to rotational freedom through a range of motion with the patient. It also uses GlideRight articulation to accommodate to a patient’s variation and soft tissue interaction while optimizing patella tracking and maintaining bone coverage. The total knee system also uses LogicLock tibial base as a central locking design that helps the architecture of the system optimize kinetics and reduce backside micromotions. Intuition instruments are also featured in the total knee system. The intuition instruments combine the surgical process with efficient instruments to help the surgeon balance soft tissue and control the implant position in patients.
The Prix Galien USA Committee may have considered the Attune knee system innovative earlier this year. But in September, a nationwide group of researchers called its usefulness into question. Their study in the Journal of Knee Surgery found an “unusually high” rate of early failure related to its tibial components.
