MRI after Knee replacement

I had a total Knee replacement march 2011 on my left Knee.  In August I hurt my right Knee and have had a MRI on it.  Since having the MRI my replacement knee has been extremely painful
. The Ortho Doctor has told me that the MRI should not have caused any problems.  Why then is my REPLACEMENT KNEE extremely sore and could you tell me if I have anything to be concerned about.  My strength in this knee seems to be getting worse and more painful.

Hi there!

MRI is a very safe method of imaging. It is not usually done post implants since the imaging tends to be distorted on exposure to magnetic field. However it may still be done in a few cases with adjusted pulse sequences and other parameters. Most implants are safe for MRI machines. The imaging study per say is unlikely to be the cause of sore knees. You may like to have this examined by your orthopedician for appropriate management.
Hope this information is helpful.

Take care!
