Superolateral Hoffa ’s Fat Pad Edema: Patellofemoral Impingement

This is a 24 year old female patients presenting with knee pain with patella alta deformity along impingement-related edema of the superolateral aspect of Hoffa ’s (infrapatellar) fat pad. Edema in superolateral Hoffa ’s fat pad may be an important indicator of underlying patellofemoral maltracking or impingement in younger, symptomatic patients.Hoffa ’s infrapatellar fat pad is one of three anterior fat pads of the knee, the other two being the anterior suprapatellar (quadriceps) and posterior suprapatellar (prefemoral) fat pads. The infrapatellar fat pad is an intracapsular structure and plays a role in stabilizing the patella in extremes of flexion and extension.  Superior to inferior, it extends from the patella to the anterior menisci and tibial periosteum and anterior to posterior, from the patella tendon to the synovial lining of the knee.Famous Radiology Blog http://www.sumerdoc.blogspot.com
