Localised tenosynovial giant cell tumour of the infrapatellar fat pad mimicking an intra-articular loose body – A case report

Abstract

Tenosynovial giant cell tumour is a benign lesion which presence in the infrapatellar fat pad is uncommon. Herein, we report a unique case of a young female patient who presented with a loose body sensation at the knee. Surgery revealed a localized swelling in the infrapatellar fat pad which was treated with an open excisional biopsy of the mass. Diagnosis of giant cell tumour is confirmed by histopathological examination.
