PATELLAR TENDON-LATERAL FEMORAL CONDYLE FRICTION SYNDROME

 

Patellar tendon-lateral femoral condyle friction syndrome, also known as Hoffa fat pad impingement syndrome, is a common cause of anterior knee pain in active individuals. It is thought to be due to patella maltracking or imbalance of the forces between medial and lateral vastus muscles causing impingement of the superolateral aspect of Hoffa fat pad between the inferior patella and the lateral femoral condyle.

Patients with Hoffa syndrome would present with acute or chronic sharp pain below the patella which is worsened by activities like walking, prolonged standing, wearing high heel shoes or any other activity that puts the knee into full extension. On examination, there may be swelling in the infrapatellar region, with point tenderness at the inferior pole of the patella.

The diagnosis is classically made with MRI and usually occult on radiography and CT. MRI findings include focal area of high T2 signal (edema) at the inferolateral aspect of the patellofemoral joint, within the superolateral portion of the infrapatellar fat pad. A cystic lesion can sometimes be found between the lateral femoral condyle and the lateral retinaculum. Associated findings include lateral patellar subluxation and patella alta (Insall-Salvati ratio greater than 1.2) which are found in around 90% of cases. Conservative treatment is usually successful, although full recovery may take time.
