Prefemoral fat pad impingement
Updates to Study Attributes
Patella alta.
Shallow dysplastic femoral trochlea (Type D).
Focal edema signal of the fat interposed between the patella and the lateral trochlear ridge, mainly along the lateral aspect.

Updates to Case Attributes
Here in this case there are features of patellofemoral instability evident by patella alta and type D trochlear dysplasia in the form of vertical link(cliff pattern) between the facets. This resulted in lateral patellar dynamic subluxation with subsequent friction and edema signal of the prefemoral pad fat mainly along the lateral aspect.
The pre-femoral fat pad or the posterior suprapatellar fat pad is located anterior to the distal femur and superior to the trochlea, separated from the quadriceps fat pad by the suprapatellar bursa.
Prefemoral fat pad impingement is caused either by:
- prominent suprapatellar osteophyte, with the edema usually in the superior aspect close to the midline
- patellar tendon-lateral femoral condyle friction syndrome, with the edema, usually occurs in the inferolateral aspect of the fat pad.
