Hoffa's disease is a disorder of the infrapatellar fat pad.
The Hoffa fat pad is the main fat pad in the knee. It protects the soft-tissue structures deep within the joint, but is itself vulnerable to injury.
Inflammation of the fat pad
Hoffa's disease is characterised by pain at the front of the knee, and often an effusion and signs suggestive of ligament instability.
