One of the most common surgeries performed by orthopedic
surgeons is a meniscectomy – or trimming of the torn meniscus and smoothing the
jagged edges of what remains. Most times, it is just assumed that this tear is
what is causing the pain.
This arthroscopic surgery is performed some 700,000 times a
year costing $4 billion. Several studies over the last 10 years have given rise
to the question of necessity of this surgery for the most common cause, wear
and tear. 80% of meniscal tears develop
over time from simple wear and tear.
The latest study out of Finland, examined 146 people with
degenerative meniscal tears (caused by wear and tear, not acute injury). One
group received standard surgery and the other a “sham” or fake surgery. After
one year, both groups reported equally favorable outcomes, which was primarily
less knee pain. In the end, the researchers concluded that the real
arthroscopic surgeries had no better outcome than the fake ones.
