MicroPort Orthopedics Debuts Evolution Tibial Cones for Revision Knee Arthroplasty

MicroPort Orthopedics Inc. has augmented its revision product line with the introduction of tibial cones for its Evolution Revision Knee System.

The Evolution Revision Knee family aims to address the significant challenges surgeons face during revision total knee arthroplasty (TKA) procedures, particularly in managing metaphyseal bone loss. “We are excited to bring this cutting-edge solution to market and continue our commitment to improving patient outcomes in joint reconstruction,” MicroPort Orthopedics Interim President Badhri Iyengar commented. “The positive feedback from the initial cases reaffirms our belief that adding the Evolution Tibial Cones to the only Medial-Pivot Revision Knee System in the market not only provides our surgeon customers with the tools they need but continues to set a new standard for patient care and experience.”
 
The Evolution Tibial Cones are constructed from OsteoSync Ti, a highly porous titanium scaffold that provides exceptional structural support and initial fixation. Manufactured by Sites Medical, the material has demonstrated excellent initial fixation and bone apposition to enhance component performance when compared with other similar substances. OsteoSync boasts a higher coefficient of friction than leading competitors—contributing to initial implant stability¹—and its bone apposition results support early rigid fixation.² Available in six symmetric sizes, the tibial cones are versatile enough to accommodate various bone defects and can be stacked up to three cones high in a single construct for cases with severe bone loss, according to the company.
 
“We designed the Evolution Tibial Cones to meet the growing need for effective solutions in revision TKA, where bone loss often complicates reliable fixation,” said Dr. Michael Anderson, a fellowship trained orthopedic surgeon at Aurora Sinai Medical Center and a key member of the design team. “These cones not only provide the necessary structural support but also allow for flexibility in surgical technique, ensuring that the final implant position is optimized for each patient.”
 
Key Features of the Evolution Tibial Cones:

• Innovative Material: Made from OsteoSync Ti, known for its excellent initial fixation and bone apposition.
• Versatile Design: Available in six symmetric sizes, with the ability to stack up to three cones for larger defects.
• Surgeon-Friendly Workflow: Offers a flexible surgical approach with options for conical reaming or broaching, based on surgeon preference.
• Enhanced Stability: Provides early rigid fixation, critical for the success of revision TKA procedures.

The first surgeries using the Evolution Tibial Cones have been successfully completed. “As a surgeon who has faced the challenges of revision knee arthroplasty firsthand, I am particularly excited about the addition of the Evolution Tibial Cones to MicroPort Orthopedics’ revision knee portfolio. These cones provide the kind of stability and versatility that we need in complex cases, especially when dealing with significant bone loss. The OsteoSync Ti material has shown impressive results in initial fixation, making it a valuable tool in ensuring successful reconstructions,” stated Donald Knapke, M.D., an orthopedic surgeon with Michigan Orthopedic Surgeons in Troy, Mich., and key design surgeon for the Evolution Tibial Cones project. “I am honored to be performing the first live case with this innovative product, and I am confident it will make a significant impact on patient care.”

The Evolution Tibial Cones are now available to surgeons throughout North America.
