Histopathology of Intraarticular Loose Body in View of the Joint-Related Vasculature - Abstract
Intraarticular loose bodies (ILBs) are not uncommon orthopedic disease. ILBs are caused by various osteoarthritic or joint diseases, some of which are associated with the joint-related vasculature. However, non-specific additional changes can occur in ILBs associated with or without the vasculature. The former represents revascularized enchondral ossification due to re-attachment of ILBs to the synovium, and the latter includes gullying of cartilaginous matrix, secondary synovial chondromatosis, and fatty metaplasia. Histopathological examination of ILBs in considering such relationship with the vasculature can be useful for assessment of the source and/or etiology of ILBs.
