Trauma is implicated as a precipitating factor. Specific diagnostic criteria are presented. The differential diagnosis of primary synovial chondromatosis includes secondary reactive synovial chondromatosis and synovial chondrosarcoma. The usual sources of osteochondritic loose bodies, on the other hand, are traumatic joint disruption, osteoarthritis, and infectious disorders. Acute primary synovial chondromatosis is adequately treated by removal of the loose bodies and synovectomy.
Postoperative prognosis is dependent on the stage of the disease at the time of surgery.
In this acute case, the patient had minimum impairment, and ankle roentgenograms twenty years after the arthrotomy were normal.
