OCD grade IV is characterized by which of the following?

Osteochondritis dissecans progression is defined by how stable the osteochondral fragment is. In the most advanced stage, the fragment has completely separated and becomes a loose body that can move freely within the joint space. This explains why the description of a fully displaced, loose fragment inside the joint best fits grade IV. The other scenarios describe non-displaced or only partially detached fragments, which do not match this final, fully displaced stage.
