ACRION Saw Blade

ACRION™ Saw Blades

ACRION™ Saw Blades are designed for joint reconstruction surgery and have large teeth engineered to provide a fast and stable cut3. Longitudinal grooves and holes aid in the ejection of debris, and the portfolio of sizes cover the characteristic dimensions of total knee replacement blocks.

Three Battery Power Line II handpieces

Battery Power Line II 

The Battery Power Line II is a powerful, efficient, and reliable bone drill/cutting system designed for hip and knee reconstruction surgeries. It’s strong enough to tackle large bone cutting but also able to accept a large portfolio of finer drilling and insertion attachments, giving it the flexibility to adapt to both major and minor orthopaedic procedures.

Fusion Saw Blades with DePuy Synthes/Zimmer coupling

Fusion Saw Blades

Fusion Saw Blades are designed for traumatology and joint reconstruction procedures and provide a less aggressive cut than our ACRION™ Saw Blades. For surgeons, this means precise1, controlled1 guidance into the bone with minimal effort.

Knee Restoration is Here

DePuy Synthes is revolutionizing what’s possible in orthopedics by enabling surgeons to restore patient knee function sooner1-3 to help achieve the next level of patient satisfaction4 by combining the kinematically advanced and clinically-proven3,6-10 ATTUNE™ Knee System with the VELYS™ Robotic-Assisted Solution and the patient-specific techniques together in a single end-to-end solution. Knee restoration is here and with it, we envision a future of better outcomes and improved patient satisfaction.

Restoring Knee Function Through Kinematics

Knee arthroplasty is a soft-tissue procedure5. The restoration of normal knee function is highly dependent on load sharing among the implant, surrounding ligaments and other supporting soft-tissue structures. 

The kinematically-designed ATTUNE™ Knee System is an integrated implant system that takes these into account and features a proprietary tibiofemoral articulation and advanced patellofemoral kinematics that enable natural rollback and rotation with reduced anterior slide.

The Most Modern Knee on the Market

The ATTUNE™ Knee System, in combination with computer assisted techniques, may deliver greater knee function2 and help achieve the next level of patient care and satisfaction4.
In fact, registry data shows that 88% of patients are satisfied with the results of their ATTUNE™ Knee TKA4, which is closing the gap of patients unsatisfied with their surgery.

ATTUNE™ Knee System is statistically significantly better than class for both patient satisfaction4 and implant survivorship5.  Additionally, global data have shown that the ATTUNE™ Knee System shortened patients’ length of stay and reduced rehabilitation referrals, compared with other leading knee systems1-3.

Patient-Specific Techniques

Patient-specific techniques target the restoration of an individual patient’s knee function and help preserve the soft tissue envelope of the knee.

Preserving Soft Tissue While Optimizing Stability

A combination of the ATTUNE™ Knee System and PSA surgical techniques is designed to help create a more stable joint within the soft tissue envelope and improve patient satisfaction.

PSA is available in both tibia-first and femur-first techniques, which are designed to maintain the natural soft tissue envelope of the knee and reduce the requirement for soft tissue releases.

The VELYS™ Robotic-Assisted Solution Optimizes Every Aspect of the Process

Another key component of the single end-to end solution is the VELYS™ Robotic-Assisted Solution, part of the VELYS™ Digital Surgery platform of connected technologies. 

Not only does it simplify knee replacement for surgeons by providing valuable insights for precise implant selection and positioning, the VELYS™ Robotic-Assisted Solution also improves efficiency for surgeons, and can help maximize patient satisfaction.

Simplicity for Better Outcomes

The VELYS™ Robotic-Assisted Solution simplifies knee replacement surgery by providing valuable insights for precise implant selection and positioning, improving efficiency for surgeons with the overall goal of improving patient outcomes at each step of the patient journey.

When the System Works in Harmony, the Patient’s Anatomy can Work in Harmony

The VELYS™ Robotic-Assisted Solution and Patient Specific Alignment (PSA) work exclusively with the ATTUNE™ Knee System which has shown to improve patient reported outcomes by working in harmony with the patient’s anatomy to deliver both stability and motion.
