In the case report presented, we describe the Reichel syndrome - synov
ial chondromatosis. The disease is monarticular, involves no trauma or
inflammation, and tends to cause a build-up of floating cartilage. It
s prognosis is good. On the basis of a review of the literature, we pr
esent its etiology, diagnosis, differential diagnosis and histology. F
or the initial treatment we recommend resection of the floating cartil
age. If the disease occurs, we recommend synovectomy in addition.
