Ortho update

Saw the ortho. Turns out fortunately it wasn't dislocated (despite what the coaches and trainers thought).
Knee is completely stable and fine. Dr. could not find any unstability or cause any pain. Based on Cole's condition in the office, no way it could have been actually dislocated, as major trauma and ligament damage would have resulted and would have still been causing lots of pain and swelling.
Most likely cause was a "hypermobile minuscus".

Meaning the minuscus has " a lack of normal meniscocapsular attachments" in the back of the knee. This can allow the minuscus to bulge out of the knee capsule, thereby causing the knee to lock and not move, as like a dislocation. This is especially caused by deep knee squats or kneeling.
Hypermobile Minuscus or The Wrisberg varient occurs in around less than 1% of the population depending on what studies you review.
According to the Dr. it just happens and there's not much that can be done about it other than to avoid the deep squats. Not too sure that's enough of an advice just yet.
We are getting an MRI of the knee on Sunday just to confirm that it really is the case. Dr. really didn't want to, oh well.
