Ggeiger is correct. there is absolutely no dislocating of the knee during arthroscopy. there are 2-3 incisions approx 1cm through which the various instruments are inserted (irrigation, camera, tool(s)). It’s about as minimally invasive a procedure as you can have done. That being said, I always remind my patients that it is still invasive, and even if they only went in to take a peak and did no surgery, you would still have pain, swelling, loss of strength and range of motion. I tell them if it was 100 years ago, they just took a couple of arrows to the knee. I think the other poster was referring to a total knee replacement, which is far more advanced (but still does not involve dislocating anything, just sawing off the end of the bone. kinda fun to watch, but not much fun to have done. hip replacements can involve dislocation in order to position correctly for the procedure)
