pivot shift test

The pivot shift test is a physical examination used by doctors to assess the stability of the knee, particularly the ACL (anterior cruciate ligament). During the test, the examiner moves the lower leg in a specific way while the knee is slightly bent, observing for a sudden "shift" or giving way sensation. A positive test indicates that the ACL may be torn or damaged, as it no longer properly stabilizes the knee. This helps doctors determine the extent of ligament injury and plan appropriate treatment or surgery.
