Hi Rajendra, Let me first clear the misconception that you are having regarding TKR surgery. It is one of the highly successful joint replacement
procedure with implant survival at 15 years being upto 98%. Both your mother & mother in law will enjoy "pain free" life upto 80 years of age after TKR. Theoritically, the complication rate after TKR surgery is 2-4%. So the benefit after TKR is 98% & risk of getting complications is 2% (benefit /risk ratio). I highly recommend TKR for them because its time tested and is being done across the globe with excellent results ( provided they do not have life threatening medical comorbidities which may increase the risk of complications).
Do you think that stem cell therapy
is totally free of complications? Its still in budding(experimental stage) phase in INDIA and the cost ???????????? I am not sure, how much it will be. Hope this is informative for you. Good day
