Cobalt chrome (CoCr) knee implants are used for knee replacements since 50 years. However, Meril has patented a new technology called Opulent Bionik Gold Knee least wear property, which is 40% lesser than regular CoCr, the hardest surface (8 times harder than CoCr), 2 times stronger than other implants of similar category and the most biocompatible non-allergic surface material.
This knee implant system, with a base science of the Freedom Knee, is a ray of hope for young and old patients who want to enjoy an active, long-term and quality performance.


The OPULENT Bionik Gold surface is for allergy and wear protection of knee implant. Macroscopically, the Bionik Gold surface presents a metallic, light golden yellow appearance whereby the coating forms an extremely strong bond with the implant.
The Bionik Gold surface prevents direct contact of the base material with the surrounding tissue and reduces the release of particles and ions due to wear.
