“There was a study done by the VA, and it was on arthroscopic surgeries, and what they did was they took a group, and this, and as a result, they changed all the policies, the VA around this, and they gave them fake surgeries. What they did is put them under just like the other group, nobody they were, Cut open the knee, just cut the flaps, sewed it back, did nothing to the knee. The other group, they did arthroscopic surgery, and what they found is after six months, the group that had no, nothing done to them improved more than the group for the surgery, and after doing the several follow-up studies to that, they no longer fund it.”

The claim, plainly

A Veterans Affairs study showed that patients receiving fake knee surgery improved more after six months than those given actual arthroscopic surgery, leading the VA to stop funding the procedure.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The claim is partially true. The landmark 2002 VA trial led by Dr. J. Bruce Moseley (published in NEJM) found that patients receiving placebo/sham knee surgery experienced initial improvements and reported equal or slightly lower pain scores at six months compared to those receiving real arthroscopic surgery, with overall outcomes showing surgery was no better than placebo. However, the study did not lead the VA to completely stop funding or banning arthroscopic knee surgery; rather, the VA and Medicare updated clinical guidelines to restrict its use for unicompartmental osteoarthritis without mechanical symptoms, while continuing to fund the procedure for appropriate clinical indications.

Moseley et al. (2002) found that at no point during 24 months of follow-up did either surgical group show statistically significant superiority over placebo, with placebo patients showing equal or numerically slightly lower pain scores at 6 months.
Following the study, the VA updated clinical guidelines to restrict knee arthroscopy for osteoarthritis without mechanical locking, but did not completely ban or stop funding the procedure across the board.
Health services data tracking VHA procedures from 1998 to 2010 showed knee arthroscopies continued to be funded and performed within the VA system.
