Can someone fracture there patellar? what would be the symptoms? i have medial pain but the swelling is lateral how can that be? please explain

Knee swelling: Knee swelling has nothing to do with the location of the pain. The knee, like most joints, has a capsule that surrounds the joint and keep the fluid contained. When there is an excess of fluid due to injury or inflammation, then the knee will swell. You will usually notice the swelling either above (proximal) the knee or the lateral aspect as these are weaker/thinner areas of the capsule.
