Knee surgery for cartilage damage does not benefit patients, study suggests. People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did not.

Analysis Summary
A 10-year randomized controlled trial found that patients who underwent meniscectomy (knee surgery to trim cartilage damage) had worse knee function and faster osteoarthritis progression than patients who received sham surgery, challenging a widely performed orthopaedic procedure. The study was published in the New England Journal of Medicine and is shifting clinical practice — some countries now recommend waiting 6 months to see if symptoms resolve before considering surgery, reducing surgery rates from 75% to roughly 25% of cases. A minority of orthopedic surgeons still see potential benefit for patients with mechanical symptoms like catching sensations, suggesting the evidence may not apply uniformly across all meniscus tear presentations.
Claims Analysis (3)
“People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did not”
10-year randomized controlled trial published in NEJM comparing meniscectomy vs sham surgery. Confirmed by The Guardian and multiple medical sources.
“Knee surgery for cartilage damage does not benefit patients”
Study found no benefit and worse outcomes for most patients. Some surgeons note potential benefit for specific subset (mechanical catching), so claim slightly overgeneralizes.
“Many independent, non-orthopaedic organisations providing clinical guidelines have recommended that meniscotomies be discontinued”
Directly quoted from Prof. Järvinen in the Guardian article. AAOS and BASK still endorse procedure, showing institutional lag in guideline adoption.
