Synovial chondromatosis

Last revised by Owen Kang on 18 Oct 2022

Synovial chondromatosis (osteochondromatosis or synovial chondrometaplasia) also known as Reichel syndrome, is a disorder characterized by loose cartilaginous bodies which may, or may not be calcified or ossified.

It is classified under two main types:

  1. primary synovial chondromatosis: predominantly monoarticular disorder of unknown etiology

  2. secondary synovial chondromatosis: resulting in intra-articular loose bodies from causes such as trauma, osteoarthrosis and neuropathic arthropathy

 In the secondary type, articular nodules are often large, vary widely in size, and frequently ossify ,in contrast to the smaller and uniformly sized in the primary type.
