"A knee that can help patients get back sooner" 1-2

The ATTUNE® Primary Total Knee System is designed with the goal of addressing the clinical needs of patients, surgeons, and hospital providers around the world. Extensive research and science is included in the design to help improve functional outcomes for patients, performance for surgeons, and efficiency for providers. The ATTUNE Knee is an innovative, comprehensive, integrated knee system.

The ATTUNE Knee is one of the largest research and development projects in the history of DePuy Synthes Joint Reconstruction and combines the latest in design, kinematics, engineering and materials to deliver stability and motion.

In an IRB approved early outcomes study, physiotherapists collected data on 40 patients implanted with ATTUNE® Knees and 40 patients with SIGMA®CR150 knees. The results demonstrated that patients implanted with the ATTUNE Knee had statistically significant improvements in some early outcomes, other outcomes demonstrated a trend favoring the ATTUNE Knee, and some outcomes were equivalent.

PMD10-Comparative Effectiveness of ATTUNE® Versus Triathlon™ Total Knee Systems: Real-World Length of Stay and Discharge Status."Value in Health 19(3): A298. Premier Perspective™ Database analysis including 38 hospitals, representing 1,178 primary, unilateral TKAs with the ATTUNE Knee and 5,707 primary, unilateral TKAs with Triathlon™. The analysis found that the patients implanted with the ATTUNE Knee had statistically shorter length of stay and were more frequently discharged home vs. a skilled nursing facility compared to the TKAs with Triathlon™.

Features & Benefits

The ATTUNE® Knee features several key proprietary technologies, exclusive to DePuy Synthes Joint Reconstruction: The ATTUNE Primary Total Knee System is designed to deliver a high level of stability and motion.

 

  Features Benefits
ATTUNE Knee with GRADIUS Curve ATTUNE GRADIUS® Curve The patented ATTUNE GRADIUS Curve is the gradually reducing femoral radius designed to provide a smooth transition from stability to rotational freedom through a patient's range of motion.
ATTUNE Knee with GLIDERIGHT Articulation GLIDERIGHT® Articulation The GLIDERIGHT Articulation encompasses a trochlear groove designed to accommodate patient variation and soft tissue interaction, and patella components designed to optimize patella tracking while maintaining bone coverage.
ATTUNE Knee with SOFCAM Contact SOFCAM® Contact The proprietary S-curve of the SOFCAM Contact is designed to provide a smooth engagement for gradual femoral rollback and stability in flexion, while reducing stresses transferred to the tibial spine.
ATTUNE Knee with LOGICLOCK Tibial Base LOGICLOCK® Tibial Base The LOGICLOCK Tibial Base has a patented central locking design that provides the architecture for the system that optimizes kinematics, while reducing backside micromotion to the lowest reported levels in the industry.1
ATTUNE Knee with S+ Technology Tibial Base with the ATTUNE S+™ Technology The ATTUNE S+ Technology is designed to enhance tibial fixation with its innovative combination of macrolock features and a microblast surface finish on the tibial base. These features are designed to provide greater residual pull off strength under a range of simulated intra-operative conditions and the presence of lipid infiltration.
