The infrapatellar fat pad - also known as Hoffa’s fat pad - is a pad of fatty tissue at the front of the knee, situated behind the patellar tendon and below and behind the kneecap (patella). If this becomes inflamed it can be a potent cause of anterior knee pain. Deep to the patellar tendon, look at the intracapsular Hoffa fat pad and check the deep infrapatellar bursa between the distal patellar tendon and the anterior aspect of the tibial epiphysis. described the MRI features of infrapatellar fat pad impingement and found evidence of patellofemoral maltracking in 38 of 42 patients who presented with anterior or anterolateral knee pain. Because disease in this region is not uncommon, it is important to be familiar with the various pathologic entities that may occur here. The infrapatellar fat pad of Hoffa is an intracapsular structure that is routinely visualized on magnetic resonance images of the knee. It was described for the first time in 1904 by Albert Hoffa and is defined as acute or chronic inflammation of the infrapatellar fat pad. This patient”s findings suggest it is probably the largest Hoffa's fat pad ever to be published in the literature. 2015 Mar; 9(3):20-26 Radiology: Posterior Hoffa's fat pad impingement secondary to a thickened infrapatellar plica: a case report and review of the literature Radu et al. Hoffa fat pad superiorly(Fig.2)25.A fat apronextendingdown from the IPFP partially divides the bursa into anterior and posterior compartments, separate from the knee joint26. Both patellar maltracking and Hoffa’s fat pad impingement are … Abnormalities that are intr … rts medial, lateral an membranes. In Hoffa’s (infrapatellar) fat pad (HFP) is one of the knee fat pads interposed between the joint capsule and the synovium. Radiology Case. Signal alterations in Hoffa's fat pad were scored semiquantitatively from 0 to 3 on the sagittal unenhanced proton density–weighted fat-suppressed images at the superior edge of the fat pad adjacent to the patella and the internal fat pad, as described previously [6, 20, 22]. Between 16 and 20 weeks, these membranes are normally resorbed and the knee becomes a single cavity. Mild distension of the bursa appears as a small triangular hypoechoic area and should be regarded as normal. The commonest traumatic lesions follow arthroscopy, but intrinsic signal abnormalities can also be … Abnormalities within it most commonly are the consequences of trauma and degeneration, but inflammatory and neoplastic diseases of the synovium can be confined to the fat pad. The infrapatellar fat pad of Hoffa is commonly injured but rarely discussed in the radiological literature. PICTORIAL REVIEW Hoffa’s fat pad abnormalities, knee pain and magnetic resonance imaging in daily practice F. Draghi 1 & G. Ferrozzi2 & L. Urciuoli3 & C. Bortolotto1 & S. Bianchi4 Received: 3 January 2016/Revised: 25 February 2016/Accepted: 26 February 2016/Published online: 21 March 2016 Located posterior to patellar tendon and anterior to the capsule, the HFP is richly innervated and, therefore, one of the sources of anterior knee pain. MRI helps in treatment decision making, as was demonstrated in our case, in which the ganglion cyst was large and was located outside the synovium but within the fat pad. Hoffa’s fat pad is a normal part of human anatomy, and acts as a … Chung et al. It is attached to the knee cartilage at the front of the knee. Every knee has a very sensitive tangerine sized piece of fat that sits behind the kneecap tendon called the Hoffa's fat pad. Hoffa's disease sometimes called hoffitis is an intrinsic disease of Hoffa's fat pad (also called the infrapatellar adipose body). The vascular supply of Hoffa's fat pad derives from the superior and inferior geniculate arteries, with a central area left paucivas-cular.
