Should I be worried about my knee swelling up on top of my knee cap overnight it feels like a waterballon?

Seek more advice: Most likely this represents swelling within your joint called an effusion or swelling outside the joint on top of the patella, called prepatellar bursitis.

Twisted knee and hit on door frame. Swelling and pain, grinding. Knee cap moves all over, seems to be floating and see-saws. Is this ligament damage?

Twisting the knee can cause ligament damage but it has to be pretty severe (unless you're 80 years old and never drank a glass of milk in your life). That "grinding" doesn't seem too comforting either. Best you get to a doctor who can examine you and decide what to do next ...Read more

However, if something more major was done like an acl, microfracture, lateral release, oats procedure this would be within normal limits. Being too active, too early after a scope will cause persistent swelling. ...Read more
