For some reason – presumably educational – a surgeon decided to wear a head cam whilst he was performing knee replacement surgery on a patient. That’s pretty much all you need to know, other than the fact it’s pretty graphic – although hopefully that would be obvious – and that it was filmed at Bega District Hospital and it’s a Stryker Triathlon total knee joint replacement.

Obviously don’t watch it if you can’t hack it, maybe watch this slow motion supercut of dogs sloberring  instead if you think it might be a bad idea.
