Infrapatellar bursitis, also known as pastor's knee, is inflammation of the superficial or deep infrapatellar bursa. [1] [4] Symptoms may include knee pain, swelling, and redness just below the kneecap. [3] It may be complicated by patellar tendonitis. [2]

Risk factors include kneeling or crawling. [5] It may also be brought on by frequent bending of the knees while standing, squatting, running, or jumping. [2] [7] Diagnosis is generally based on symptom and physical examination. [2] When the deep bursa is involved, bending the knee generally increases the pain. [3] Other conditions that may appear similar include patellar tendonitis and prepatellar bursitis. [6]

Treatment is generally by rest, alternating between ice and heat, and NSAIDs. [2] Infrapatellar bursitis is relatively rare. [5] Due to the kneeling being enjoined in church services, infrapatellar bursitis has also been called pastor's knee, vicar's knee and clergyman's knee. [1] [2] [3]
