What happens to a knee if it pops out of socket?

When a knee pops out of its socket, it typically indicates a dislocation, which occurs when the bones of the knee joint are forced out of their normal alignment. This can cause severe pain, swelling, and an inability to move the joint. Immediate medical attention is necessary to realign the bones and prevent damage to surrounding ligaments, nerves, and blood vessels. Following treatment, rehabilitation is often required to restore mobility and strength.
