I had to intubate patients as part of my clinical time for paramedic, which meant time in the OR. Some surgeons would let us hang out and watch the surgery. Orthopedic surgery sounded like a cross between a construction site and an automotive shop. Die grinders, saws, and power drills.

Also, apparently knee replacement involves one guy doing MMA submission moves on the patient’s leg while another goes at their exposed, hyper-flexed knee joint with a hammer and chisel.
