Fat pad impingement (Hoffa’s Syndrome)
What is it?
The fat pad is a soft tissue structure that sits below the kneecap (patella) right behind the patellar tendon. The fat pad acts as a cushion, protecting the condyle of the femur from being hit by the patella in the case of a direct blow to the kneecap. The fat pad contains many nerves, and at the time of injury, one experiences extreme knee pain. A person’s hip and/or knee alignment can cause the fat pad to become irritated and impinged.
