Superficial infrapatellar bursitis
Infrapatellar bursitis (or clergyman's knee) occurs with inflammation of bursae around the insertion of the distal patellar tendon. The inflamed bursa may be:
- superficial/subcutaneous: anterior to the distal patellar tendon
- deep: posterior to the distal patellar tendon, in the region of the infrapatellar fat pad (Hoffa's fat pad).
Radiographic features
Inflammation of an infrapatellar bursa is well detected on either targeted musculoskeletal ultrasound or on MRI.
