Mechanisms of selected knee injuries.

Mechanisms of knee injury are very complex and depend on multiple factors. The purpose of this article was to describe mechanisms of knee injury. Causes of knee injury include microtrauma and macrotrauma. For microtrauma, mention was made of the accumulation of inflammatory reactions that eventually produces clinical signs and symptoms. For macrotrauma, particular emphasis was placed upon immediate injuries resulting in straight one-plane instabilities and transverse plane rotatory instabilities.
