My understanding is that for swelling to exist that means something with blood supply was torn, parts of the meniscus, ligament …. So I find it odd to define a dislocated knee in the manner you are saying.
In order for the knee to dislocate something has to tear. I did give an extreme example but that’s the typical association. Maybe you can have a displaced knee with minor tears but for the knee to be truly dislocated there’s going to be massive damage. I don’t think it’s accurate to define a dislocated knee in the manner you are saying. I respect your experience on this but I’ll just have to disagree on this one.
What do you think the final result will be?
Swelling does stem from small capillaries leaking fluid. Like you said lot of it comes from ligamentous tears, dislocations, sprains, etc.
Yes more than likely ligaments will be torn and your patella will move out of place. That’s your typical patellar dislocation. A typical dislocation is the bone separation from the joints. A painful injury.
The example you gave of Zach Miller is 100% different. He tore his popliteal artery which is the major blood supply that runs from mid thigh to the lower leg. That’s extremely severe and rare.
Couldn’t tell you what the final result will be without seeing the MRI. Just saying a dislocation can’t be ruled out because the knee looked to pop laterally and that’s how the majority of knee dislocations occur.
