Also known as “housemaid’s knee”, pre-patellar bursitis refers to inflammation and swelling of the bursa located between the kneecap (patella) and overlying skin.
A bursa is a fluid filled sac which allows adjacent tissues to slide over one another without friction; the pre-patellar bursa is located superficially on the anterior aspect the knee between the skin and the patella.
Injury occurs following either a single injury or a series of injuries to the bursa for example a single blow to the knee. Alternatively repeated kneeling can cause minor trauma that builds up over time resulting in the swelling of the bursa and subsequent bursitis.
Management initially should be to use the “PRICE regime” and Physiotherapy will aim to modulate pain, correct abnormal biomechanics and analyse training techniques.
In severe cases debridement of the wound and dissection of the prepatellar bursa (Kaiser et al., 2015).
