Suprapatellar Fat Pad Impingement due to Vascular Lesion

Abstract

Case: We present a fifteen-year-old adolescent boy with anterior knee pain and a palpable tender swelling in the suprapatellar region with painful terminal extension. Imaging was suggestive of a vascular lesion in the suprapatellar fat pad. He underwent arthroscopic debridement and postoperatively regained his terminal extension.Conclusion: Suprapatellar fat pad impingement can rarely be due to vascular lesions or lipomatous tumors affecting the suprapatellar fat pad. If conservative treatment is unsuccessful, surgery can provide good pain relief. The tissue excised should always be sent for histopathological examination.Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/C74).
