Biomechanical progress of fatigue effect on non-contact anterior cruciate ligament injury / 中国组织工程研究

ABSTRACT

BACKGROUND:Anterior cruciate ligament injury can trigger knee instability, knee osteoarthritis which decreases human beings’ life quality. Exploration on non-contact anterior cruciate ligament injury mechanism can prevent the occurrence of anterior cruciate ligament injury. OBJECTIVE:To investigate the mechanism of fatigue effect on non-contact anterior cruciate ligament injury and to introduce the progression of fatigue effect on non-contact anterior cruciate ligament injury in jump-landing activities. METHODS:The author retrieved the PubMed database from 1988 to 2013 by computer. The key words were set asACL, landing, and fatigue. A total of 42 articles were included which related to biomechanics research on anterior cruciate ligament injury, fatigue landing and low-limb injury. RESULTS AND CONCLUSION:In jump-landing activities, knee valgus, moment, knee joint rotation and smal er knee flexion are main biomechanics underlying non-contact anterior cruciate ligament injury. In addition, fatigue effect is another critical factor for non-contact anterior cruciate ligament injury. However, the cause-effect between fatigue effect and anterior cruciate ligament injury is not clearly investigated and summarized, especial y on fatigue level, fatigue induction and movement control. Introduction of fatigue induction is crucial for better understanding how fatigue effect results in anterior cruciate ligament injury. Thus, the quantification of fatigue level, fatigue models and landing ways wil provide new ideas for exploring biomechanical mechanism underlying anterior cruciate ligament injury in fatigue state, as wel as provide more information on intervention design and injury rehabilitation.
