Knee Surgery No Help for Arthritis
Posted by Jacob Goldstein

Surgeons take it as an article of faith that a chance to cut is a chance to cure. So it’s a pretty big deal when a study clearly shows that a common surgery doesn’t actually help certain patients. Even more so if the study is confirming similar results from a previous study.

That’s what happened this week, when the New England Journal of Medicine published a study that showed arthroscopic surgery doesn’t provide any benefit for moderate to severe arthritis of the knee.

Researchers randomly assigned nearly 200 patients to receive either surgery, drugs and physical therapy, or drugs and physical therapy alone. 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.

A 2002 study had similar results.

“We now have two independent, well-controlled trials that demonstrate that the procedure is ineffective,” Brian Feagan, one of the authors of the new study, told the WSJ. “I think that will change practice.” For more on the study, see the video interview by the HealthCare Channel with another one of the authors, Robert Litchfield of the Fowler Kennedy Sport Medicine Clinic in Ontario.

Bonus Scans: Another study in the NEJM found that MRI scans of middle-aged and older people commonly detected tears of the meniscus in the knee, often without any accompanying pain or stiffness. The results suggest that doctors who order MRIs to assess knee problems be cautious in interpreting tears as problems that require surgical treatment. 这个应该需要进一步的证实 本人已认领该文编译,48小时后若未提交译文,请其他战友自由认领。 [标签:content1][标签:content2]
