Isn’t that amazing! I had double knee replacement 3 years ago at Mayo Clinic and had same outcome. I just sent X-rays to the surgeon for follow up and they said the knees look fine even though in the report I filled out I had expressed issues with pain and stiffness. As long as X-rays look fine they don’t care about any other issues you may have. I have lost a great deal of respect for the Doctors that I have dealt with at the Mayo Clinic. Not helpful in trying to resolve issues.
