The prepatellar bursa and the olecranon bursa are the two bursae that are most likely to become infected, or septic. [10] Septic bursitis typically occurs when the trauma to the knee causes an abrasion , though it is also possible for the infection to be caused by bacteria traveling through the blood from a pre-existing infection site.

Prepatellar bursitis, also known as housemaid's knee, is a common cause of swelling and pain above the patella (kneecap), and is due to inflammation of the prepatellar bursa. It is common in people who frequently kneel , such as roofers, plumbers, carpet layers, and gardeners.
A distension of this bursa is therefore generally an indication of knee effusion. [3] the prepatellar bursa between the patella and the skin [2] It allows movement of the skin over the underlying patella. the deep infrapatellar bursa between the upper part of the tibia and the patellar ligament.

Prepatellar bursitis (kneecap bursitis) Cysts; Tumours; Repetitive strain injury; Having osteoarthritis or engaging in high-risk sports that involve rapid cut-and-run movements of the knee — football or tennis, for example — means an individual is more likely to develop water on the knee.
The [deep] infrapatellar bursa is located under the patella, between the patellar ligament and the fibrous membrane of the joint capsule. It is communicating with the joint space in particular cases. Other less regularly present bursae include the subfascial prepatellar, the subtendinous prepatellar, and the subcutaneous prepatellar bursae.
“Rupture of a bursa,” like Johnson’s, “is more rare than bursitis itself,” Siddiqi says. There are two main forms of bursa ruptures: septic, when the sac swells to fight an infection ...
Patellofemoral pain syndrome can become a chronic injury, with an estimated 50% of people reporting persistent patellar-femoral pain after a year. [32] Risk factors for a prolonged recovery (or persistent condition) include age (older athletes), females, increased body weight, a reduction in muscle strength, time to seek care, and in those who ...
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.
