Case Discussion

This condition results from the overstimulation of the knee extensor mechanism due to friction during physical activities and results in of the Hoffa's fat in the inferior aspect of the patella. It is often related to patella alta.

In this case, the patient has been exercising daily with running activities and recently presented with an anterior knee pain.  Within this medical history and MRI findings, the diagnosis of Hoffa fat pad impingement syndrome should be considered.
