My mom is going to have bilateral knee replacement surgery in India. From the conversation with my parents, what I figured, the doctor is going to use oxinium Knee replacement implant (which is from Smith and nephew). From another source, I was suggested to use Johnson and Johnson knee implant. Which one is best and what should I know before going for knee replacement implant? What could be the implant cost per knee implant (for one leg)? Any pros and cons?
