Terms, definitions and their use within this manuscript to describe ACL injuries in football (valid for team sports)

TermDefinition and use
Injury mechanismThis term describes the ACL injury causation, referring to player-to-player interaction that led to the injury. Three categories have been used: (1) non-contact, (2) indirect contact and (3) direct contact.
Situational patternThis term describes the situation leading to ACL injuries. The patterns can be divided into defensive and offensive situations. This is the situation and not just the action, in that it considers the action interacting with the environment (eg, pressing pattern).
Biomechanics of injuryThis term refers to the kinematics or intersegmental body segment relationships at initial contact and suspected injury frame on the frontal and sagittal planes.
