Hoffa’s fat pad impingement treated arthroscopically: related findings on preoperative MRI in a case series of 62 patients

摘要

Introduction The morphology of painful impingement of the infrapatellar fat pad (Hoffa’s disease), which is characterized by inflammation, swelling, hypertrophy, fibrosis, and/or calcifications, has been well described. The purpose of this study was to investigate whether corresponding characteristic MRI findings could be assessed in patients with infrapatellar fat pad impingement.
