Abstract
IntroductionA synovial chondromatosis is a rare benign neoplasm on the synovium. 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 presentationA 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.ConclusionsAlthough 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.

Summary
A synovial chondromatosis is a rare benign neoplasm that is caused by metaplasia of the synovium into chondrocytes [1]. To further scrutinize these calcifications, a magnetic resonance imaging (MRI) scan was recommended It showed an extensive thickening of the patient’s synovium, multiple intraarticular calcific and ossific loose bodies, and large calcified bursal extensions. The bursal component extended into the patient’s posterior distal thigh and his proximal calf These findings were thought to be consistent with very extensive synovial chondromatosis (Figure 1). The patient underwent weekly physiotherapy sessions focusing on quadriceps strengthening, with a daily exercise regime to supplement this He recovered well and three months after the operation, has regained his right knee’s full range of movement with flexion increased to 130 degrees, which is equal to that of his left knee. He has residual medial joint line tenderness, undoubtedly due to osteoarthritis
