The infrapatellar (Hoffa's) fatpad is an important structure within the knee, whose function and role are both poorly understood. This review explores the anatomy, neural innervation, vascularity, role in biomechanics, pathology, imaging (stressing the importance of dynamic ultrasound assessment) and treatment of disorders presenting within this structure.
