Prepatellar bursitis, also known as "housemaid's knee," is common among individuals who frequently kneel on hard surfaces without knee pads. It presents with swelling and redness over the kneecap, which may be tender to the touch. Aspiration and corticosteroid injection is a common treatment option. The other options are less likely given the patient's occupation and presentation.
