INFRAPATELLAR FAT PAD SYNDROME “Hoffa’s Syndrome”
The Infrapatellar Fat Pad is a soft tissue structure that lies just posterior to the patella in what is called the anterior interval. Although, there is no definitive function of the fat pad, it is said to be the buffer for direct forces placed on the anterior knee as well as protect the underlying structures. When direct force occurs to the patella pinching of the fat pad between the femoral condyle and/or tibial plateau can result. Due to the increased vascularity and nerve innervation of the fat pad, increased pinching will eventually lead to sharp anterior knee pain.
