Three Advanced Components, One Revolutionary Surgical Solution

DePuy Synthes is enabling surgeons to restore patient knee function sooner1-3 with next level patient satisfaction4, by offering an end-to-end solution. This single solution combines the ATTUNE™ Knee System with the proprietary Patient-Specific Techniques, and VELYS™ Robotic-Assisted Solution to help enhance surgical accuracy, precision and predictability. Surgeons enjoy greater ease of use. Patients get back on their feet, faster1-3. One knee solution, endless steps forward.


DePuy Synthes Knee Solutions is a natural fit for providing end-to-end solutions, including the implant, techniques and technology for surgeons’ success throughout the entire care continuum. One key component is the ATTUNE™ Knee System.

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.6

​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

The next key component of our single end-to-end surgical solution is the Patient Specific Alignment (PSA) surgical techniques.​

Preserving Soft Tissue While Optimising Functional Implant 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 a surgical philosophy that aims to preserve soft tissues while optimising implant stability for every patient within tested & validated boundaries. ​

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.​

VELYS™ Robotic-Assisted Solution

The VELYS™ Robotic-Assisted Solution Optimises 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 efficiency7 for surgeons and can help maximise patient satisfaction.8,9

Simplicity for Better Outcomes

The VELYS™ Robotic-Assisted Solution simplifies knee replacement surgery by providing valuable insights for precise implant selection and positioning, improving efficiency7 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 outcomes10 by working in harmony with the patient’s anatomy to deliver both stability and motion.11-14

Knee Restoration is Here

DePuy Synthes is revolutionising 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-proven3,12-16 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.
