It typically results from a hard blow to the front of the knee or falling on the knee. [1] The patella can also be fractured indirectly. For example, a sudden contraction of the quadriceps muscle in the knee can pull apart the patella. [1] Diagnosis is based on symptoms and confirmed with X-rays. [3] In children an MRI may be required. [3]

Lead is the most common shield against X-rays because of its high density (11,340 kg/m 3), stopping power, ease of installation and low cost. The maximum range of a high-energy photon such as an X-ray in matter is infinite; at every point in the matter traversed by the photon, there is a probability of interaction.
The Ottawa knee rules are a set of rules used to help physicians determine whether an x-ray of the knee is needed. [1] They state that an X-ray is required only in patients who have an acute knee injury with one or more of the following: Age 55 years or older; Tenderness at head of fibula; Isolated tenderness of patella

A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
It can thus serve as a surrogate radio-opaque marker of the posterior border of the knee's synovium. On a lateral radiograph of the knee, an increase in the distance from the fabella to the femur or to the tibia can be suggestive of fluid or of a mass within the synovial fossa. This is of particular use in radiographic detection of knee ...
