We report the results of arthroscopic removal of loose bodies and abnormal synovium from 18 knees with primary synovial chondromatosis. After a mean of three years, six months (range one to 10 years), 14 knees were either symptom-free or had only minor symptoms. Three of these had required two arthroscopic operations. Three patients were improved but not cured and there was one failure. The res...

Synovial chondromatosis is a benign idiopathic metaplasia of the synovial membrane. It affects one in 100000 persons. It is 3 times more common in males, arising between 30 and 50 years of age and mainly affects large joints such as the knees (70%), hips (20%) and shoulders (19%). Its etiology is unknown, although it has been associated with chromosomal mutations (p21.3 and 12q13) that affect p...

OBJECTIVES Tenosynovial chondromatosis is an uncommon type of chondro-dysplasia of synovial and connective tissue. We report a case of a patient with a primary right wrist extra-articular chondromatosis extending to the flexor and the extensor compartments. METHODS Until now, there has been no study describing double surgical access for such a case. RESULTS Due to the extension, two surgica...

Synovial chondromatosis (SC) is a cartilaginous metaplasy of the mesenchymal remnants of the synovial tissue of the joints. It is characterized by the formation of cartilaginous nodules in the synovium and inside the articular space (loose bodies). SC mainly affects to big synovial joints such as the knee and the elbow, being uncommon the onset within the TMJ, where 75 cases have been published...

When cartilage-like tissue is present in the synovial membrane of joints, it known as chondromatosis (SC). The main cause believed to be metaplasia embryonal mesenchymal membrane. metaplastic foci grow within joint space and can detach from wall, forming free-floating bodies. While SC more commonly associated with trauma temporomandibular (TMJ), exact relationship between remains unclear. Impro...
