This is astounding! A July 2002 Medscape article showed arthroscopic knee lavage or debridement was no better than placebo surgery in a randomized controlled trial described in the New England Journal of Medicine.
“During two years of follow-up, patients in all three groups reported moderate improvements in pain and functional ability, but neither the debridement nor the lavage group fared better than the placebo group. At certain points during follow-up, subjects receiving sham surgery reported better outcomes than those receiving debridement.”
