Dr. Chintan Hegde, a leading orthopedic surgeon at Thunga Hospital, Mumbai, has successfully performed India’s first knee replacement using the Evolution® NitrX™ Medial-Pivot Knee implant system. This advanced implant features the innovative NitrX™ coating, designed to reduce metal ion release and improve patient outcomes.
Dr. Hegde explains that many patients visit him with advanced arthritis, severe deformities, swelling, and pain in both knees, often struggling with daily activities such as climbing stairs or standing for extended periods. After detailed evaluation, he recommends total knee replacement surgery to restore mobility and improve quality of life.
Sharing his experience, Dr. Hegde said, “I have been using the Evolution® Medial-Pivot Knee for some time and I am impressed with the stability and natural motion it provides. Recently, I used the version with the NitrX™ coating, which offers an added advantage by reducing wear, tear, and potential metal ion release. Patients report excellent flexion, comfort, and confidence while performing everyday tasks.”
The golden-colored implant owes its appearance to the NitrX™ coating, which creates a barrier against the release of cobalt, chromium, and nickel ions. This may help reduce soft tissue reactions linked to metal sensitivity.
The Evolution® Medial-Pivot Knee is manufactured by MicroPort Orthopedics Inc., a Tennessee, USA–based global medical device company. Commenting on its adoption in India, Dr. Mukesh Parmar, Senior Director & General Manager for South Asia at MicroPort Orthopedics, said:
“Globally, the Evolution® Medial-Pivot Knee has achieved 98.8% survivorship at 17 years and a 95% patient satisfaction rate. With over 25 years of clinical success and more than one million cases worldwide, we are delighted to see its growing use in India, where we have recently surpassed 1,000 implantations with excellent outcomes.”
While this innovation brings new possibilities, each patient is unique, and surgical outcomes may vary. Patients considering knee replacement should consult a qualified orthopedic specialist, as risks and recovery timelines are part of the surgical process.
