Pathology

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. It is also common in wrestlers due to the repeated impact on the knee when shooting.[1][2]

Symptoms

Symptoms include knee pain, swelling, redness and inability to flex the knee on the affected side. Rest usually relieves symptoms. Physical exam reveals erythema, tenderness to touch, fluctuant edema over the lower pole of the patella and crepitus.

Treatment

General treatments consist of bursal aspiration, NSAIDs. For patients with high athletic or occupational demands, intrabursal steroid injection may be performed. Surgical treatment is restricted to severe cases.
