How much does it cost to have a bilateral total knee replacement surgery using oxinium implants in India

The cost of total knee replacement is comparatively lesser in India vs. the western nations. Cost ranges between 2 to 3.5 lakhs for a single TKR while a bilateral TKR costs around 5 to 6 lakhs. However, a single seating bilateral TKR is less costly than bilateral TKR done in separate seatings. However, oxinium implants may cost more 70 to 80 thousand more. Selection of the knee implant type is a vital aspect of TKR. It involves consideration of multiple aspects such as ROM, type of metal alloy composition and most importantly, cost of the implants in a country like India. Durability of the implant is as vital as any other aspects listed above. Average durability of any TKR implant ranges from 15 to 20 years.

Gradually, the implant gets subjected to normal wear and tear due to varied forces and begins to lose its quality and strength. This wear and tear gives rise to metal debris into the joint. Hence, it is vital to select an implant that is highly non-reactive to biological components to prevent any hypersensitive reactions arising from the metal debris. Co-Cr and oxinium alloys are a couple of such highly effective materials. Oxinium alloy is composed of two of the most biologically inert metals known till today. TKR implants composed from oxinium possess excellent resistance against fracture and wear. Hence, they prove to be highly favourable materials to manufacture TKR implants.

Theoretical benefits associated with oxinium implants are as follows: 1) >0.0035% detectable Nickel which leads to reactions. 2) Ceramic coating over metal leading in less wear and tear and resulting into higher durability. 3) No evident bioreactivity and is biocompatible. 4) 20% lighter vs. Co-Cr. However, real-world studies have failed to demonstrate considerable difference in terms of safety and effectiveness between Co-Cr and oxinium implants.
