1.1) FAT PAD IMPINGEMENT Acute trauma or repetitive microtrauma to a fat pad can cause haemorrhage and inflammation. The QFP is located between the suprapatellar recess and the distal quadriceps tendon. Pain and catching were observed in the proximal-lateral patellofemoral joint, and MRI imaging confirmed a hyperplasic mass in the same area. suprapatellar fat-pad impingement syndrome which may be related to chronic microtrauma. References . There are 2 patterns of focal prefemoral fat pad edema: (A) Superior central edema, directly related to a prominent superior patellar osteophyte impinging on the pad; (B) inferolateral edema, with suggested mechanism being a prior sheer injury or impingement. Hoffa's disease. The fat pad has abundant nerve innervation, which makes it one of the most pain-sensitive structures in the knee. Three distinct fat-pads are located in the anterior knee compartment: the suprapatellar or quadriceps fatpad, the prefemoral or supratroch-lear fat-pad, and the infrapatellar or Hoffa fat-pad. Suprapatella Injection--Spreading the "plane" between the quadriceps fat pad & the prefemoral fat pad in a 59 year old female Prefemoral fat pad Quadriceps fat pad MRI summary Objective: To determine if qualitative and quantitative measures of prefemoral fat pad (PFP) and quad-riceps fat pad (QFP) are associated with incident radiographic osteoarthritis (iROA) over 4 years in the Osteoarthritis Initiative (OAI) study. These intra-capsular but extra-synovial fat pads have been considered to act as protective cushions accommodating the changing volume and shape of irregular articular spaces during joint movement 5 . Case . Symptomatic impingement of the prefemoral fat pad can be clinically significant but easily overlooked on magnetic resonance imaging, unless looked for. The third one is infrapatellar: the Hoffa fat pad. Epub 2006 Dec 6. Read "Prefemoral fat pad: impingement and a mass-like protrusion on the lateral femoral condyle causing mechanical symptoms, Knee Surgery, Sports Traumatology, Arthroscopy" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at … Pain may be worse when barefoot or wearing flat shoes compared with a heeled shoe The fat pad is tender to touch – this will be below the patella and deep to the patella tendon; A puffy anterior knee – the fat pad is a bit like a sponge and when inflamed will become engorged in fluid (9). There were no significant associations between quadriceps fat pad mass effect and the signal intensity of the prefemoral fat pad (χ 2 = 0.1358, p = 0.7125) or the Hoffa fat pad … Name the fat pads in the anterior compartment of the knee. Each is interposed between the joint capsule externally and the synovium-lined joint cavity and its extensions internally, making it intracapsular but extrasynovial. Prefemoral fat pad: impingement and a mass-like protrusion on the lateral femoral condyle causing mechanical symptoms. MRI. Because of the proximity of the fat pad and it’s surrounding structures, the symptoms of fat pad irritation are often mistaken for patella femoral pain syndrome or patella-tendinitis. The term ‘quadriceps fat-pad impingement’ has been used to describe an inﬂammatory process within the anterior suprapatellar fat, manifested on MRI as high T2 signal, low T1 signal and mass effect on the quadriceps tendon. The posterior suprapatellar or prefemoral fat pad (PFP) is located posteriorly to the suprapatellar bursa, superiorly to the trochlea and anteriorly to the anterior cortical of the distal femoral metaphysis. 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. 15(6): p. 786-789. Kohl, S., et al., Anterior knee pain after total knee arthroplasty: does it correlate with patellar blood flow? Two of them are suprapatellar; the quadriceps (or suprapatellar) fat pad (QFP) is anterior and the prefemoral fat pad is posterior, located just behind the suprapatellar recess. A case of prefemoral fat pad impingement syndrome caused by hyperplastic fat pad. Prefemoral fat pad impingement. We describe a case of prefemoral fat pad impingement between the anterior aspect of the distal femur and the patella undersurface, and a mass-like fatty tissue protrusion on the lateral femoral condyle that caused mechanical symptoms. I worry, as do you, about how limited and painful your injury is to project how much improvement you will gain in the next 3-6 months. We describe a case of prefemoral fat pad impingement between the anterior aspect of the distal femur and the patella undersurface, and a mass-like fatty tissue protrusion on the lateral femoral condyle that caused mechanical symptoms. Pain and catching were observed in the proximal-lateral patellofemoral joint, and MRI imaging confirmed a hyperplasic mass in the same area. Of these, one of the most common is quadriceps/suprapatellar fat-pad impingement syndrome which may be related to chronic microtrauma. A case report.

Our case presents an HIV patient with Hoffa’s fat-pad inflammation as well as prefemoral fat-pad edema, posterior soft-tissue inflammation, and bone infarction. Diagnostic and Interventional Imaging - Vol. AX and SAG PD and T1. If this becomes inflamed it can be a potent cause of anterior knee pain. We report a rare case of prefemoral fat pad impingement syndrome that was caused by a hyperplasia of the normal suprapatellar fat pad. The prefemoral fat pad, the third intracapsular fat pad of the knee, has not been systematically evaluated. Although conservative treatment showed no signs of improvement, symptoms improved after an arthroscopic … The Hoffa fat pad was equal to fat in 89% (82/92), intermediate signal in 3% (3/92), and fluid signal in 8% (7/92) .
