Predicting the MRI results
Metadata[+] Show full item record
In an article published in the New England Journal of Medicine, researchers decided to create a study of meniscal surgery using a sham surgical control.1 Researchers randomized 146 patients with a nontraumatic meniscal tear (and little or no arthritis of the knee) to either meniscal repair or fake meniscal repair. Every patient started with an arthroscopy and, once the internal damage was confirmed, received either meniscectomy or some detailed stagecraft during which the surgeons made noise and pantomimed a surgical procedure. Then everyone received the same graded exercise program.
