Abstract: Synovial chondromatosis and parameniscal cysts are well documented pathologies around the knee joint.
We present an unusual presentation of synovial chondromatosis masquerading as a parameniscal cyst of the
knee. The patient was an 82-year old gentleman seen in our knee clinic with painful swelling over medial
aspect of the right knee, no history of injury and with symptoms of a locked knee. Clinico-radiological
features were suggestive of a binary pathology of a meniscal tear and multi-locular cyst of the knee. An
arthroscopic assisted open excision of the cystic lesion allowed clinical recovery with histological
confirmation of benign synovial chondromatosis.
We highlight the challenges in our case with the overlap of diagnostic features of both synovial and meniscal
pathology with surgical management of this patient.Keywords: Knee, synovial chondromatosis, para meniscal cyst, magnetic Resonance Imaging, knee arthroscopy
