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

Risk factors include kneeling or crawling. ^[4] It may also be brought on by frequent bending of the knees while standing, squatting, running, or jumping. ^{[1] [6]} Diagnosis is generally based on symptom and physical examination. ^[1] When the deep bursa is involved, bending the knee generally increases the pain. ^[2] Other conditions that may appear similar include patellar tendonitis and prepatellar bursitis. ^[5]

Treatment is generally by rest, alternating between ice and heat, and NSAIDs. ^[1] Infrapatellar bursitis is relatively rare. ^[4] It has also been called vicar's knee and clergyman's knee. ^{[1] [2]}
