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.

Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis , injury to the ligaments or meniscus , or fluid collecting in the bursa , a condition known as prepatellar bursitis .
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. [2] It allows for movement of the patellar ...
Patellar subluxation syndrome is an injury involving the kneecap. Patellar subluxation is more common than patellar dislocation and is just as disabling. [1] In this condition, the patella repetitively subluxates and places strain on the medial restraints and excessive stress/tension on the patellofemoral joint. Patellar subluxation can be ...
The articular capsule of the knee joint is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. [1] The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly. [2]

The condition may result from acute injury to the patella or chronic friction between the patella and a groove in the femur through which it passes during knee flexion. [11] Possible causes include a tight iliotibial band, neuromas, bursitis, overuse, malalignment, core instability, and patellar maltracking. [citation needed]
