Abstract:

OBJECTIVE: To understand biomechanical characteristics of knee joint ligament to reveal the causes for ligament injury of the knee joint, so as to provide suggestions of knee joint prevention, treatment, functional recovery and reconstruction material optimization for college students during sports exercise.
METHODS: A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and Wanfang database (http://www.wanfangdata.com.cn) was performed for related articles published between 2006 and 2010, with the key words “knee joint, biomechanics, sports injury, artificial ligament, material optimization” in English and Chinese. Articles involving biomechanical characteristics of knee joint, general causes, prevention, treatment and functional recovery of knee joint ligament and reconstruction material to repair ligament breakage were included. Repetitive studies were excluded.
RESULTS: A total of 566 articles were collected, and 18 were included for further analysis following title reading and abstract screening.
CONCLUSION: Ligament injury of the knee joint is common in sports exercise and greatly damages students body quality. Studies of biomechanical characteristics, rehabilitation, and reconstruction material to repair ligament breakage benefit prevention, treatment and functional recovery of knee injury of college students during sports exercise, which also promote students health and carry out positive sports exercise. With developing material medicine, artificial ligament has been used clinically, which obtains favorable effect in short and middle period of time. Biodegradation of polymer in combination with cytokine treatment, in vitro cell culture and gene transfection techniques help to confirm basic theory of ligament repair and substitution. A novel ligament substitution should be developed to reach requirements of artificial ligament.
