Orthopedic Products Symmetric Knee

Symmetric Knee Implant Systems

The Symmetric Knee Systems feature a single radius femoral component, which is engineered to optimize polyethylene surface contact for enhanced stress distribution across the joint. Additionally, the systems incorporate two key innovations for long-term stability and implant integrity.

  1. The Micro Seal® technology, a unique locking mechanism, securely anchors the polyethylene liner to the tibial tray. This design minimizes micromotion and effectively seals out joint fluid, mitigating the risk of osteolysis around the screw interface.
  2. The tibial component benefits from an Arc-deposited Titanium (Ti) coating. This porous surface fosters robust bone in-growth and on-growth, ensuring firm fixation and reducing the potential for implant loosening.

Together, these advanced features are designed to minimize the likelihood of future osteolysis or inflammation, which supports long-term bone health and implant stability.
