Total knee replacement is generally performed in older patients with osteoarthritis. For the first time in India, a new prosthesis will be introduced for young osteoarthritis patients. This prosthesis made of a wonderful material called Zirconium, a ceramic coated metal ensures a longer survival of the prosthesis after implantation. The introduction of this prosthesis is expected to encourage more young and middle-aged Indians and Westerners to undergo knee replacement in India.

Advantages of zirconium

1) The significant advantage of zirconia knee implants is that they are considerably harder. In tests, it lasts 85 times longer in tests that simulate the stresses within the real knee. Additional advantages are scratch resistance.

2) When wet, ceramic can slide smoothly on plastic, allowing smoother movement than metal on plastic. As a result, the Oxinium total knee replacement will not generate the amount of plastic wear debris that cobalt chrome will, and the implants should last considerably longer. Zirconium is one of the six most biocompatible elements known to man. Therefore, your immune system will more easily tolerate your new implant.

3) Finally, patients allergic to nickel, the metal most used in current implants, cannot currently receive total knee replacement. However, the ceramic implant can be safely implanted in patients with a nickel allergy, as it uses a nickel-free zirconium alloy. Implants made from Oxinium have been implanted in a larger number of patients in the UK, Australia and the US with great success.

Who would benefit the most from a total knee replacement with oxynium (zirconium)?

Three types of patients have been identified as the “best” candidates for total knee replacement with Oxinium.

“Younger” patients: Because Oxinium knee implants offer significantly less wear compared to cobalt chrome implants, they are expected to last considerably longer. In the past, orthopedic surgeons advised patients under 65 to wait before undergoing knee replacement surgery because the lifespan of cobalt chromium knee implants is only 10-15 years. Now, surgeons have a viable option for a younger patient who previously would not be a candidate for a total knee replacement because Oxinium knee implants should last much longer. Therefore, a patient under the age of 65 who has advanced knee arthritis no longer has to suffer for years until they reach a suitable age for total knee replacement surgery.

“Active” Patients: Patients who want to return to an active lifestyle, including sports, dancing, gardening, or other strenuous activities, may also benefit from a knee replacement with Oxinium. As a result of their high level of activity, this patient population will put more “wear and tear” on their knee replacement, which can cause implants to wear out more quickly. An Oxinium knee is better able to tolerate this high level of activity and lasts longer than the traditional cobalt chrome knee. Metal Allergy Patients: Because oxynium is one of the most biocompatible materials known to man, it is the only option for patients with metal allergies. Patients who have needed total knee replacement surgery, but were unable to tolerate cobalt chromium implants due to their nickel content, can now undergo the surgery they need to return to an active lifestyle without fear of suffering. an allergic reaction

The first patient will be a middle-aged housewife with osteoarthritis. While normal knee replacements cost around Rs 80,000, this new prosthesis may cost around Rs 1.25 lakhs, but is comparable to the best in its class. The higher cost will be offset by the longer implant survival. A Total Knee Package is available to Indians and foreigners with normal and long-lasting prosthetics at affordable prices.
