Which symptom is associated with a joint that has been dislocated?

A dislocated joint typically presents with joint deformity as the most notable symptom. When a joint is dislocated, the bones that form the joint are forced out of their normal positions. This misalignment causes visible changes in the joint's shape or position, leading to a distinct deformity.

Increased flexibility, reduced swelling, and normal alignment are not associated with a dislocated joint. In fact, dislocations often result in reduced flexibility due to pain and tissue damage. Swelling usually occurs rather than being reduced, as the body responds to injury with inflammation. Lastly, normal alignment is not characteristic of a dislocated joint because the very definition of a dislocation involves the loss of that normal anatomical arrangement.
