  A bursa is a closed fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. When a bursa becomes inflamed, the condition is known as bursitis. Most commonly, bursitis is caused by local soft tissue trauma or strain injury. […] Knee bursitis can be caused by: […] Frequent and sustained pressure, such as from kneeling […] A direct blow to your knee […] Frequent falls on your knee […] Bacterial infection of the bursa […] Complications from osteoarthritis, rheumatoid arthritis or gout in your knee. […] Excessive Kneeling. People who work on their knees for long periods of time, such as carpet layers, plumbers and gardeners, are at increased risk of knee bursitis. […] Participation in Certain Sports. Sports that result in direct blows or frequent falls on the knee, such as wrestling, football and volleyball, may increase your risk of knee bursitis. Runners may develop pain and inflammation in the anserine bursa, located on the inner side of your knee below the joint. […] Obesity and Osteoarthritis. Anserine bursitis, affecting the inner side of your knee below the joint, often occurs in obese women with osteoarthritis.

  A lime- or grapefruit-sized lump at the front of the knee may be a sign of prepatellar bursitis. Prepatellar bursitis occurs when the bursa at the front of the knee becomes inflamed and fills with excess fluid. […] There are many reasons a prepatellar bursa may become inflamed, such as repeated irritation, an injury, or an underlying inflammatory condition. Repeated irritation from kneeling is the most common reason. […] Experts estimate about 1/3 of prepatellar bursitis cases may be caused by an infection. […] When a bursa is infected the bursa sac fills with puss. This condition is called septic bursitis, and requires urgent treatment. […] Bacteria and other microorganisms typically enter a superficial bursa through a scrape or cut. Less often, microorganisms enter a bursa during an aspiration, a procedure to remove fluid from the bursa. […] It is possible for an infection to occur without an obvious entry point on the skin.

  Knee bursitis: causes, symptoms, home remedies […] Causes of prepatellar bursitis […] Bursitis can occur where there is a direct blow to the area which causes bleeding into the bursae. This will occur quickly, usually immediately at the time of the incident. Examples of such trauma might be tripping and falling directly onto the knee. […] The biggest cause of irritation to the pre-patellar bursae is repetitive kneeling. […] Another cause, not previously mentioned is due to infection. […] Prepatellar bursitis looks the same, but there are two very different causes for this diagnosis. You can have an infective bursitis (medical professionals will refer to this as a septic bursitis), or a non-septic bursitis resulting from inflammation. […] It is very important to differentiate between these two types as the septic bursitis can be very dangerous and treatment for this is very different.

  Septic bursitis (SB) results from infection of the bursal sac, which is frequently caused by skin lesions but can also arise from secondary spread of infection from initial cellulitis into a pretraumatized superficial bursa or, in rare cases, from hematogenous seeding. Infection is commonly caused by bacteria (most often Staphylococcus aureus) but can in rare cases result from fungi. The prepatellar bursa is the bursa most commonly involved in Brucella infection. […] Up to 50% of all SB cases occur in immunocompromised patients. Other risk factors include chronic rheumatic inflammatory diseases.

  The prepatellar bursa is a flat, round, synovial-lined structure; its main function is to separate the patella from the patellar tendon and skin. This bursa is superficial, suggesting that it is undeveloped at birth. Within the first few months to years of life, the bursa arises from direct pressure and friction. It reduces friction between the skin and the patella and allows maximal range of motion (ROM). […] Nonseptic bursitis (NSB) is a sterile inflammation that develops secondary to occupational or athletic trauma, crystal deposition (gout, pseudogout), or systemic disease, such as rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, or uremia. Most cases of NSB result from chronic microtrauma caused by repetitive friction. Particularly vulnerable are individuals continually exposed to compressive and sheer forces between the skin and the patella bone, including members of occupational groups whose job requires frequent kneeling or crawling (eg, carpenters, gardeners, roofers) and athletes participating in sports such as ice hockey, volleyball, and wrestling. The inflammatory response causes an overproduction of bursal fluid and subsequent bursal swelling, resulting in NSB.

  Infection in the bursa, also known as septic bursitis, results from bacterial contamination. It causes symptoms like redness, warmth, severe pain, and sometimes fever, requiring immediate medical attention to prevent complications. […] Gout, osteoarthritis, and rheumatoid arthritis contribute to bursitis by causing joint inflammation and additional stress on the bursa. These chronic conditions often exacerbate the severity and duration of bursitis symptoms. […] Some people are more prone to knee bursitis due to lifestyle, occupational activities, or existing health conditions. Factors like prolonged kneeling, obesity, and joint-related diseases increase susceptibility. […] Jobs involving frequent kneeling, such as gardening or construction, increase susceptibility. […] Obesity places excessive strain on the knee joints due to increased body weight. This added pressure makes the bursa more susceptible to irritation and inflammation, heightening the risk of bursitis development.

  Bursitis of the Knee is a painful condition in which one or more of the 11 bursa sacs in the knee become irritated and inflamed, affecting the bursa and the soft tissue around it. […] If the bursa fills with blood, it is usually due to trauma – a specific injury such as a fall or perhaps even a car accident. […] Poor posture, knee joint degeneration (arthritis, osteoarthritis), auto-immune disorders (gout, psoriasis, thyroid disease), previous surgical intervention, bone spurs / calcium deposits, prolonged kneeling and leg-length discrepancy (one leg is shorter than the other) are all risk factors for knee bursitis. […] Basically, degenerative conditions affecting the knee or any type of injury or condition that alters the way you walk, stand or sit can lead to a change in the position of the bones and tissue in the knee joint – and these changes in positioning can result in knee bursitis.

  Diseases like rheumatoid arthritis or systemic lupus erythematosus, involving chronic inflammation, can contribute to knee bursitis. […] As individuals age, the bursae may undergo wear and tear, becoming more susceptible to inflammation. […] The mechanism of knee bursitis often involves repetitive stress or pressure on the bursae. […] Continuous pressure or repetitive stress can lead to increased friction, causing irritation and inflammation of the bursae. […] In knee bursitis, an overproduction of synovial fluid occurs as a response to irritation, leading to swelling and discomfort. […] The inflammatory response triggered by overuse or trauma can disrupt the normal healing process. […] Weakness or imbalance in the muscles surrounding the knee can contribute to abnormal stress on the bursae. […] Factors such as poor posture, improper body mechanics, or structural abnormalities in the knee joint can contribute to the development of knee bursitis.

  Prepatellar bursitis is the inflammation of a small sac of fluid located in front of the kneecap. This inflammation can cause many problems in the knee. […] Bursitis is the inflammation of a bursa. The prepatellar bursa can become irritated and inflamed in a number of ways. […] In some cases, a direct blow or a fall onto the knee can damage the bursa. This usually causes bleeding into the bursa sac, because the blood vessels in the tissues that make up the bursa are damaged and torn. […] The blood in the bursa is thought to cause an inflammatory reaction. The walls of the bursa may thicken and remain thickened and tender even after the blood has been absorbed by the body. This thickening and swelling of the bursa is referred to as prepatellar bursitis. […] Prepatellar bursitis can also occur over a longer period of time. People who work on their knees, such as carpet layers and plumbers, can repeatedly injure the bursa. This repeated injury can lead to irritation and thickening of the bursa over time. The chronic irritation leads to prepatellar bursitis in the end.
