ATTUNE S+™ Technology with Macrolock and Microblast
The ATTUNE S+™ Technology is yet another way that DePuy Synthes is driving evidence-based innovation intended to make continuous enhancements with the goal of positively affecting patient outcomes and satisfaction. The tibial base with the patented ATTUNE S+ Technology (U.S. Patent No. 10,307,260) includes added features designed to provide greater residual pull off strength under a range of simulated intra-operative conditions and the presence of lipid infiltration and motion. 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.
Features & Benefits
Increased surface roughness designed to work with macrolock to provide a greater level of residual fixation under simulated intraoperative conditions and lipid infiltration compared to other implants tested.1
Four Cement Pockets; designed to provide additional macro mechanical fixation with cured cement. 45 degree undercuts; macro geometry designed to provide a macro-lock between cement–implant interface.
ATTUNE Knee Proprietary Technologies
This tibial tray incorporates the original ATTUNE Knee patented technologies that deliver improved patient satisfaction.2
Based on our clinical heritage, the central cone design of the ATTUNE Rotating Platform Tibial Base allows the tibial insert to rotate as the knee flexes, which allows for a more natural motion and may reduce the stress and wear on the implant.3,4,5
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.
