It is caused by kneeling for long periods or repetitive knee movements

Housemaid’s knee or prepatellar bursitis is caused by kneeling for long periods or repetitive knee movements. In this condition, the fluid builds up in the bursa (the sac of fluid that cushions the knee joints), resulting in swelling behind the knee called ‘Baker’s cyst’. It can also be caused by injuries or arthritis.

Bursitis is generally an inflammation of a bursa, a small sac of fluid with a thin lining. Our body has a number of bursae, which are generally found in places where there has been unusual pressure or friction and where tendons and ligaments pass over the bones.
