My dad went through full knee replacement surgery in Nagpur. Rehab is a long process, and I am sure the painkillers are helping, but so far, he is doing well and is able to walk without pain. I am very impressed with the quality of doctor and the process he went through. Everything required was available in one private hospital and the cost is very reasonable. The out-of-pocket expenses for one knee replacement turned out to be around 2 Lakhs (~$2,500). Given my dad served in military, the whole cost was absorbed by Indian government military insurance.
Out of curiosity, I inquired about what would it cost to do this process without insurance in USA. Turns out to be around ~70K and that’s excluding rehab. No wonder medical tourism is so popular and will continue to be.
