title: Rotatory knee laxity.
abstract: Evaluation of injured-knee laxity is essential for treatment selection, clinical follow-up, and research. Interest in rotatory knee laxity increased with implementation of anatomic anterior cruciate ligament reconstruction. The pivot shift test represents a link between static testing with 1° of freedom and dynamic testing during functional activity. Difficulties lie in standardizing the performance of the pivot shift test and extracting measurable and relevant kinematic data. Noninvasive methodologies based on electromagnetic or acceleration sensors can evaluate the pivot shift in a quantitative and reliable manner. Further validation and reliability testing of devices for examination of rotatory laxity is warranted.
