ATTUNE™Knee System

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 a 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.

Features & Benefits

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.

LOGICLOCK™ Tibial Base

The LOGICLOCK™ Tibial Base has a patented central locking design that provides the architecture for the system that improves kinematics, while reducing backside micromotion to the lowest reported levels in the industry¹.

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.

GLIDERIGHT™ Articulation

The GLIDERIGHT™ Articulation encompasses a trochlear groove designed to accommodate patient variation and soft tissue interaction, and patella components designed to improve patella tracking while maintaining bone coverage.

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.

INTUITION™ Instruments

The INTUITION™ Instruments combine the surgical process with intuitive and efficient instruments to allow the surgeon to balance the soft tissue and precisely control the implant position and fit for each patient.

Surgeons share their experience and evidence with ATTUNE.

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™.
