Current understanding of static anterior and rotational knee laxity measurements: How can they be of use for athletes' health protection?

Several devices have been developed to measure anterior and rotational static knee laxity over the last decades. Knee laxity measurements have the advantages of precisely quantifying laxity and are thus potentially more objective than manual tests. They may systematically be part of follow-up of knee injuries as they allow to study laxity in the non-injured knee, to improve the diagnosis of ACL injuries and to follow up reconstructions. Recent advances in physiologic laxity measurements showed that they may be of interest for the identification of knee injury risk factors in athletes. However, further efforts are necessary to improve the use of rotational laxity measurements in the daily clinical practice. Moreover, further prospective follow-ups of knee laxity in the injured/reconstructed knees are required to conclude on the best treatment strategy for knee soft tissue injuries.
