Research raises questions about efficacy of knee surgery

A Sept. 2008 posting on the Wall Street Journal Health blog raised questions about knee surgery’s effectiveness for treating arthritis in the knee.  In the article, Jacob Goldstein references several research studies published in the New England Journal of Medicine.

“Researchers randomly assigned nearly 200 patients to receive either surgery, drugs and physical therapy, or drugs and physical therapy alone (for knee pain and dysfunction.) Three months later, patients who had surgery had slightly less pain than those who did not. But there was no significant difference between the two groups at six months, one year or two years. The difference at two years was the main measure the researchers looked at.”
