The primary causes of prepatellar bursitis include acute trauma resulting from a direct fall onto the knee, and microtraumas occurring from prolonged or repetitive contact of the knee with the ground. In cases of acute trauma, blood vessels within the bursa can be damaged, leading to bleeding into the bursa. This hemorrhage can be more severe, especially in individuals with blood clotting disorders or elderly patients taking anticoagulant medication. If not treated early and appropriately, the bursa walls can thicken, and the blood tissue and fluids within it can become dense, transforming the condition into a more difficult-to-treat chronic process. In individuals working in professions that require repetitive or continuous kneeling (such as miners, gardeners, carpet layers, mechanics), pathological changes can occur in the bursa due to constant, albeit less severe, exposure, leading to fluid accumulation accompanied by pain and swelling. Infections, and low-grade inflammatory conditions such as gout, syphilis, tuberculosis, or rheumatoid arthritis are other factors that can cause prepatellar bursitis.
