Doctor: Most likely your description sounds like you may have a liquid collection in your prepatellar bursa produced maybe by p previous traumatism. The prepatellar bursa is a superficial bursa with a thin synovial lining located between the skin and the patella. Normally, it does not communicate with the joint space and contains a minimal amount of fluid; however, inflammation of the prepatellar bursa results in marked increase of fluid within its space. The recommended treatment would be: relative rest, avoid kneeling or additional stress on the knee, you can take anti inflammatory medication (“Aleve”, “Advil”), then physical therapy to control pain and swelling , mobilizations to regain any loss of Range Of Motion, exercises to increase the flexibility and strength of the quadriceps and hamstrings.
