Osteochondral-Fracture: Journals

An osteochondral fracture (OCF) occurs when a fragment of a smooth surface breaks at the bone base. It happens in a joint when the articulating cartilage (chondro) and part of the underlying bone (osteo) falls off the bone and becomes a fragment itself. If the fragment remains in place it will be considered stable but if it breaks loose it will be labeled unstable. Unstable fractures in the joint can move around, causing pain and other symptoms too. Those fragments, or loose bodies, may differ in size. Typically as fragment size increases a person becomes more symptomatic.  The injury mechanism most often occurs in a position of weight-bearing with a twisting or torquing force at the joint. A lateral dislocation of the patella occurs another potential cause of the OCF.
