✅ Overview

Patellar tendon-lateral femoral condyle friction syndrome, also known as Hoffa fat pad impingement syndrome, is a common cause of anterior knee pain, especially in active individuals. 

It results from patellar maltracking or an imbalance between the medial and lateral vastus muscles, leading to impingement of the superolateral aspect of the Hoffa fat pad between the inferior patella and the lateral femoral condyle.

 

✅ Clinical Presentation

• Anterior knee pain worsens with hyperextension
• Point tenderness at the inferior pole of the patella
• Thickened fat pad, making patella palpation difficult
• Associated conditions: patella alta and lateral patellar subluxation

 

✅ MRI Findings

• Focal high T2 signal (edema) at the inferolateral patellofemoral joint
• Involvement of the superolateral portion of the infrapatellar fat pad
• Possible cystic lesion between the lateral femoral condyle and lateral retinaculum
• Strong association with lateral patellar subluxation and patella alta (seen in ~90% of cases)
