Q. How successful s minimally invasive surgery for knee replacements?

A. Approximately 300,000 knee replacements are performed each year in the United States. and it said that 90% of the people who had a total knee replacement report an improvement in their function. i searched the CDC statistics for failure of the surgery and couldn't find any info about it. but as i said- it's a very common surgery. my grandmother had a hip joint replacement due to arthritis, it helped.
here is something that might help you to prepare for the surgery:
