Knee surgery: We found no evidence of benefit from the procedure, with a suggestion of worse outcomes after arthroscopic partial meniscectomy than after sham surgery. 10-year follow-up of Teppo Järvinen’s randomised trial. https://t.co/7b3PvzpZm8

PI Teppo Järvinen @shamteppo talks about the placebo-surgery FIDELITY Trial 👉
Results have been published twice in @NEJM (2013, 2026)
🔍 Arthroscopic Partial Meniscectomy provides no benefit and may even be harmful. Link to the last publication: https://t.co/tljFidhHes

[FICEBO @ficebo]

The FIDELITY trial’s 10-year NEJM results are out. This placebo surgery–controlled trial showed no benefit from arthroscopic partial meniscectomy at 1 year (NEJM 2013), and now suggests there may even be harm at 10 years. In this short interview, PI Teppo Järvinen explains why it matters. Full publication: https://t.co/DD7yhs1tkq

Useless, unnecessary, and now harmful surgery of meniscal tear proven in a trial that followed patients for ten years!

[Alan Cassels @AKECassels]

Alex Berenson's reporting of the famous Finnish Fidelity Trial on meniscectomy is fabulous.

People don't like to be told the surgery they underwent was useless. How will they feel when they are told it was likely harmful? https://t.co/9eTKM4tB3z

A widely used knee surgery may not just be ineffective — it may cause harm.
