General objective of this article is to explain Causes and Prevention Patellar Dislocation. Patellar dislocations can happen for various causes, starting from contact to non-contact predicaments. An athlete involved inside impact or contact activities can suffer from it because of a sudden change in direction, causing a twisting action around the kneecap and a pursuing dislocation. This is classified as non-contact since it doesn’t involve a third bash. One of the pre-requisites because of this to happen is the existence of the weak knee ligament to hold on to the knee properly constantly in place. Another method is a principal impact onto the knee, causing a much more dangerous injury.
