Duraniom

India’s first US-made, US FDA–cleared TiNbN-coated knee implant. Backed by over 32 years of clinical history and a commitment to continuously evolving patient needs, Duraniom brings together the proven traditional J-curve design with an advanced Titanium Niobium Nitride (TiNbN)–infused surface. This combination is engineered to deliver reliable performance, enhanced durability, and improved biocompatibility for long-term clinical confidence.

Product Information

Duraniom builds upon the original Consensus® Knee design rationale and elevates it with a revolutionary TiNbN surface coating. This advanced coating enhances implant performance by reducing wear, improving biocompatibility, and addressing concerns related to metal sensitivity—while maintaining the trusted kinematics of a proven knee system.

Benefits

TiNbN-coated implants help mitigate risks associated with elevated ALVAL values, thereby reducing the likelihood of adverse local tissue reactions.Allergy Protective Effect
TiNbN-coated implants significantly reduce the release of metal ions such as nickel, chromium, cobalt, and molybdenum into the body. This helps minimize inflammation and lowers the risk of early implant loosening, making it suitable for patients with metal sensitivity concerns.

Reduced Wear & Improved Biocompatibility

The TiNbN coating enhances surface biocompatibility while significantly reducing implant wear,

supporting long-term durability and smoother joint performance.

Reduced Coefficient of Friction (CoF)

TiNbN exhibits a lower coefficient of friction (≈ 0.04–0.07) compared to conventional CoCr alloys (≈ 0.08). This enables smoother articulation, reduced wear, and improved implant longevity.

Four Times Harder than Conventional CoCr Alloys

With a surface hardness of approximately 24 GPa, the TiNbN coating is significantly harder than standard CoCr alloys, providing superior wear and corrosion resistance.

Reduced Risk of Adverse Local Tissue Reactions
