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]
Bursae are readily inflamed when irritated, as their walls are very thin. [7]: p. 22 Along with the pes anserine bursa, the prepatellar bursa is one of the most common bursae to cause knee pain when inflamed. [9] Prepatellar bursitis is caused by either a single instance of acute trauma to the knee

Patellar tendon rupture is a tear of the tendon that connects the knee cap (patella) to the tibia. [1] Often there is sudden onset of pain and walking is difficult. [1] In a complete rupture, the ability to extend that knee is decreased. [1] A pop may be felt when it occurs. [2]

Immune deficiencies, including HIV and diabetes, can also cause bursitis. [1] Traumatic injury is another cause of bursitis. The inflammation irritates because the bursa no longer fits in the original small area between the bone and the functionary muscle or tendon. When the bone increases pressure upon the bursa, bursitis results.
What is a ruptured bursa sac? Bursa sacs are small, thin pouches, or sacs, of fluid found at many points on the body, including the elbows, hips and kneecaps. They act as cushions for bony ...
