Superficial infrapatellar bursitis (clergyman knee) is located more distally than prepatellar bursitis and is often caused by frequent kneeling in an upright position. It can also be seen in gout or syphilis. The differential diagnosis includes Osgood-Schlatter disease. The deep infrapatellar bursa is less frequently inflamed.

Clinically, the patient exhibits pain with flexion and extension at the extremes of the range of motion. Edema is located on both sides of the patellar tendon and is associated with tenderness.
