A sprain, ligament strain or twist of the knee is an injury to the ligaments of the knee due to strain, excessive stretching, twisting or tearing.
It originates when the joint area is affected by mechanical action (the demand of a rough movement, excessive articular opening or closing, anti-natural movement), or by violence (fall, blow).
It causes inflammation and pain (at first intense, later decreasing), causing functional impotence and even temporary paralysis of the knee.
It is diagnosed by performing medical questioning, physical examination of the knee and imaging tests such as radiography and/or MRI.
Depending on the type of sprain, conservative (rest, painkillers) or surgical treatment will be required.
