re: Marcelo accidently breaks guy's leg

Is that actually his XR or just a stock google image knee dislocation? Without question one of the few true orthopaedic emergencies. There are a lot of people who think they’ve had a “knee dislocation” when really it’s just a patellar dislocation. Aside from the fact that you have to shred every ligament holding the knee to dislocate it like this, the real concern is vascular. Amputation is not an infrequent sequelae after this injury. And if you avoid that, you are stuck with a severe multiligamentous knee injury with a low chance of ever being close to the same.
