Cause: Rupture of the anterior cruciate ligament usually occurs during running with fast changes of direction or as the result of a fall while skiing. Most injuries occur without contact with an opponent.
Symptoms: Usually a snap can be heard or felt and continued sports activity must be aborted. The knee swells within the first few hours, after which the knee can not bend completely. You can subsequently often sense that the leg gives way (knee failure). Acute treatment: Click here. Examination: If a partial or complete rupture of the cruciate ligament is suspected, you should seek medical attention (casualty ward) immediately, to obtain a diagnosis. The doctor can perform various tests on the knee (front drawer looseness, Lachmann, Pivot shift) to examine the stability of the knee. It should be noted that the looseness in the knee can often only be demonstrated after two weeks. The fluid in the knee can be drained. Blood in the knee provides a very strong suspicion of a rupture of the anterior cruciate ligament. The bleeding that occurs after a rupture of the anterior cruciate ligament can usually be seen in an ultrasound scan (Ultrasonic image) (article) or MR-scan. Arthroscopy (a telescopic examination of the knee) is the best suited examination if there is any doubt in the diagnosis.
