Patellar tendon lateral femoral condyle friction syndrome

Patellar tendon lateral femoral condyle friction syndrome, also called Hoffa fat pad impingement syndrome, is a condition causing anterior knee pain from the superolateral infrapatellar fat pad being compressed between the patellar tendon and the lateral femoral condyle. 

It is often linked to patellar maltracking or muscle imbalances and can result in pain, tenderness, and difficulty with activities like running or squatting. Treatment can involve conservative methods like activity modification and physical therapy, or surgery if conservative options fail.
