title: Benign synovioma presenting as mechanical abnormality in large lower limb joints.
abstract: Benign synovioma is a rare cause of symptomatic instability of joints of the lower limb. We report two cases presenting in this way. Arthrotomy is indicated to ensure adequate excision of these lesions if recurrence is to be avoided.
