Abstract

Anterior cruciate ligament, or ACL, injuries are among the most common athletic injuries that occur in the world. While many studies focus on understanding which sports pose the greatest risk for ACL injuries and the differences in injury rates between female and male athletes, there have been fewer studies compare ACL injury rates among different countries. This paper reviews the studies that have examined ACL injury rates in different countries, to help understand whether there may be genetic or geographic contributions to differences in these rates. This information can guide the design for future prospective studies on international ACL injuries.
