Arthroscopic Knee Surgery Isn't Going to Fix Your Knee

The video discusses the use of sham surgeries to evaluate the effectiveness of arthroscopic knee surgery for osteoarthritis. A BMJ paper reviewed multiple trials and found minimal benefits and significant risks associated with the surgery. Despite this, the procedure remains common, with ethical concerns raised about sham surgeries. The video concludes with a call for viewer support.
