Knee bursitis is a condition in which one or more small fluid-filled sacs near the knee joint become inflamed. The sacs are called bursae. Bursae reduce friction and cushion pressure points between bones and tendons, muscles and skin near the joints.
Any of the bursae in the knee can be affected by painful swelling, also called inflammation. But most often, knee bursitis happens over the kneecap or on the inner side of the knee below the joint.
Causes
Frequent kneeling: Most cases of prepatellar bursitis are caused by pressure and irritation from frequent kneeling.
A direct hit to the knee: Trauma to your knee from falling or getting hit with something can cause prepatellar bursitis.
Bacterial infection: If you have a scratch, insect bite or cut on your knee that becomes infected, it can spread to your prepatellar bursa sac. This kind of prepatellar bursitis is called infectious bursitis. It’s not as common, but it’s a serious condition that needs immediate medical treatment.
Having rheumatoid arthritis and/or gout: Although it’s not as common, both rheumatoid arthritis and gout can cause prepatellar bursitis
And finally ,it’s important to contact your healthcare provider immediately or go to the nearest hospital. Infected prepatellar bursitis needs medical treatment. If left untreated, it can cause serious and life-threatening complications. These informations are gotten from cleaveland clinics.
