Unable to process the form. A high-riding patella, a short distance between the patellar ligament and the lateral trochlear facet, and an increased distance from the tibial tubercle to the trochlear groove are associated with superolateral Hoffa fat pad edema at MR imaging. Hoffa's syndrome, also known as infrapatellar fat pad syndrome, is a problem which affects one of three pads of fatty soft tissue that lies under the kneecap (patella) and leads to pain at the front of the knee. Ultrasound appearances ofHoffa's fat pad impingement syndromefrom patellar maltracking. The fat below the caudal margin of the patella shows an abnormal increased signal (arrows), associated with moderate patella alta.

In prefemoral fat pad impingement syndrome, the cause is either secondary to a prominent suprapatellar osteophyte, with the edema usually in the superior aspect of the prefemoral fat pad close to the midline or secondary to patellar tendon-lateral femoral condyle friction syndrome, with the edema, usually in the inferolateral aspect of the fat pad. There are various fat pads, but the one at the knee that causes a lot of problems is the infrapatellar fat pad, also known as Hoffa's fat pad after the man who first described it. Structurally it is composed of adipose tissue similar to subcutaneous fat 1. This syndrome was first described by Hoffa in 1904. Five classic bone contusion patterns have been described 1-4:.

Hoffa's fat pad is a normal part of the human anatomy, and acts as a shock-absorber to cushion the patella and stop it from hitting off the femur (thigh bone) in the case of a direct blow to the front of the knee. The fat pad is spongy fat tissue located just below the kneecap, which means any bad positioning of the kneecap can compress and irritate it, causing pain. Hoffa fat pad impingement syndrome occurs secondary to patellar maltracking or imbalance of the forces between medial and lateral vastus muscles causing impingement of the superolateral aspect of Hoffa fat pad between the inferior patella and the lateral femoral condyle. The fat pad is intraarticular meaning it actually sits within the joint but outside the synovium (joint capsule). Hoffa impingement.
