Although described as a benign disease it can be very destructive and can cause severe osteoarthritis and pain. To the best of our knowledge we report the first known case of an extensive presentation of this intra-articular and extra-articular disease of the knee joint. Case presentation A 49-year-old Caucasian man presented with right knee pain and stiffness caused by diffuse intra-articular and extra-articular synovial chondromatosis. He underwent careful preoperative imaging and planning followed by a two-stage arthroscopic and open procedure in order to completely eradicate the disease. He has regained full range of movement but continues to experience residual pain due to severe osteoarthritis. Conclusions Although synovial chondromatosis is described as a benign disease it can be very destructive and debilitating. A challenging management dilemma arises when confronted with both synovial chondromatosis and osteoarthritis. Introduction A synovial chondromatosis is a rare benign neoplasm that is caused by metaplasia of the synovium into chondrocytes 1 . The aetiology of the disease is uncertain.
