Severe Pain After Knee Replacement May Foretell Outcome

By October 8, 2011

Follow me on:

According to a report presented at the 2011 World Congress on Osteoarthritis, patients who have severe pain within the first 3 months following total knee replacement surgery have worse pain and function at one and 2 years post-op and are less satisfied with the procedure than patients who do not experience severe pain within the first 3 months. Patients who are depressed and those who view their pain level as worse than it actually is also are more likely to experience severe post-op pain.

About 15% of patients experience severe pain after knee replacement surgery, but until now, it was not associated necessarily with poor long-term outcomes. Researchers concluded there was a link after studying WOMAC Osteoarthritis Index scores of a group of 622 patients who had knee replacement surgery. Researchers suggested that cognitive behavioral therapy, pain management, and antidepressants may be helpful when indicated before surgery or after -- as well as considering surgery sooner, before pain becomes too severe.

I had knee replacement 2 years ago. Every quarter the surgeon removes 50 ccs of water which is clean and clear and also then gives a cortizone injection. Why is this knee filling with water? We are supposing it is the synovial tissue weeping but are not sure . Do you have any ideas?
