Intra articular loose bodies
Dr MT Niknejad and Dr Frank Gaillard et al.
Intra articular loose bodies can result from a variety of pathological processes.
Use of the term loose is frowned upon by some because the fragments do not necessarily rattle around in the joint : the term intraarticular fragment is a safer alternative.
Patients may be entirely asymptomatic, or complain of pain, clicking and locking, depending on the location and mobility of the fragment as well as any associated secondary degenerative disease, and symptoms from the underlying cause.
Causes include
- osteochondral fractures
- osteochondritis dissecans
- pigmented villonodular synovitis (PVNS)
- osteoarthritis
- intra-articular fracture fragments
- synovial osteochondromatosis
- neuropathic joints
- meniscal fragmentation and its calcification
