Knee Replacement Launches: ATTUNE Cementless, Persona Revision and Sterizo Total Knee

Knee segment leaders DePuy Synthes (#3) and Zimmer Biomet (#1) enhanced their offerings and noted that their new knee systems combined with their robotic-assisted systems will boost revenue. Smaller player Fuse Medical launched its next-generation total knee platform and announced further product launches for 2020. Detail of these new systems follow. 



DePuy Synthes
commenced limited launch of the ATTUNE® Cementless Knee in a rotating platform option in select global markets. ATTUNE Cementless is suitable for a younger, active patient and combines proprietary technologies of the ATTUNE Knee that address stability with DePuy Synthes’ rotating platform knees and cementless technology.

The ATTUNE Cementless Knee is initially being launched in the United States, select countries in Europe, Japan, Australia and New Zealand, with additional launches to follow. It is available in a Cruciate Retaining and Posterior Stabilized Rotating Platform construct, as well as a hybrid construct (cementless Femoral Component with a cemented Fixed Bearing or Rotating Platform Tibial base). All of the bone interfacing surfaces of the ATTUNE Cementless Femoral Component are coated with POROCOAT Porous Coating and the ATTUNE Cementless Rotating Platform Tibial Base features four porous-coated pegs and a central cone to enhance fixation. INTUITION Instruments allow the surgeon to balance the soft tissue and control patient-specific implant position and fit.

The complete ATTUNE platform includes a cemented primary knee, revision knee and a tibial base with ATTUNE S+ Technology designed to enhance intraoperative tibial fixation. As with the cemented primary and revision systems, ATTUNE Cementless features the ATTUNE GRADIUS Curve for stability through the range of motion and GLIDERIGHT Articulation to replicate the normal relationship between the patella and femur.

Company leadership believes that future launch of Orthotaxy robotic-assisted technology combined with a cementless knee will drive the company to at or above market growth. (Knee sales have been eroding for several quarters.)

“With the ATTUNE Cementless Knee, we have carried forward technologies and learnings from clinically proven devices like the LCS Knee and combined that with ATTUNE Knee patented technologies to provide our customers a compelling solution to meeting emerging patient needs,” said Rajit Kamal, Vice President and Global Franchise Leader, Knees, DePuy Synthes. “Our strong hope and belief is that this implant system will help younger, more active patients get back to doing what they love if their surgeon feels they are the right candidate.”

The first ATTUNE knee design received FDA 510(k) clearance in 2010.



Fuse Medical
introduced the Sterizo Total Knee, a next-generation platform based on proven and accepted design principles. Sterizo is designed to offer high flexion with a high range of motion, and stabilization options include Cruciate Retained, Ultra Congruent Anterior Stabilized and Posterior Stabilized.

Sterizo is accompanied by a stackable, two-tray modular instrument system to help reduce sterile processing costs. In 2020, the company intends to launch a revision knee as well as a primary total hip.



Zimmer Biomet
received an additional FDA 510(k) clearance for the Persona® Revision Knee. Initial U.S. launch is underway; full launch is slated for 2020. This revision model completes the company’s portfolio of Persona patient-personalized designs. Persona Revision received its first 510(k) clearance in 4Q18. The very first Persona design was cleared in 2012.

Persona Revision features Zimmer Biomet’s Trabecular Metal™ porous biomaterial and the Vivacit-E® Highly Crosslinked Polyethylene (HXPE) bearing surface. Persona knees are compatible with the company’s ROSA® Knee robot, along with Vanguard® and NexGen® systems.

The ROSA Knee system remains in limited launch, with overall unit placements noted as “relatively small” by leadership in their latest earnings call. The company is committing more resources to robotics R&D, as well as commercial infrastructure.

“Persona Revision completes Zimmer Biomet’s flagship Persona knee system and enhances our ecosystem of customer-centric solutions that address the needs of our customers and improve patient outcomes,” said Ivan Tornos, Zimmer Biomet’s Group President of Global Orthopedics. “The highly-anticipated release of Persona Revision provides surgeons with a full portfolio for the continuum of knee arthroplasty care and the ability to truly tailor an implant solution based on each patient’s unique requirements.”
