Case Discussion
Secondary synovial osteochondromatosis is distinguished from primary entity by florid evidence of osteoarthritic changes, lack of extensive synovial proliferation and picture of mutliple trapped synovial cysts. A complicated Baker's cyst as it is adds on to the myriad of causes of knee pain in this patient.
