This study was conducted to determine risk factors for second anterior cruciate ligament (ACL) injury using return-to-sport (RTS) tests consisting of qualitative and quantitative measures in young athletes.<\/p>\n
All athletes completed an RTS test consisting of qualitative and quantitative assessments and psychological assessments. Athlete demographics, surgical characteristics and sports participation were also examined.<\/p>\n
In 72 eligible athletes, 12 suffered a second ACL injury. One variable that showed the lowest p-value in the preliminary analysis was entered into the binary logistic regression, which resulted in that qualitative assessment of knee valgus during the sidestep cut was associated with second ACL injury.<\/p>\n
Athletes who demonstrated excessive dynamic knee valgus on the involved limb during the sidestep cut were approximately 4.6 times more likely to suffer a second ACL injury.<\/p>\n
Quantitative assessments, such as strength and hop test performance, and psychological assessments are frequently used as part of return-to-sport testing after anterior cruciate ligament (ACL) reconstruction (ACLR) and have been found to predict second ACL injury.<\/p>\n
This study identifies qualitative risk factors for second ACL injury in adolescent athletes. Excessive knee valgus during a cutting task was associated with second ACL injury after primary ACLR in adolescent athletes.<\/p>\n
A set of qualitative assessment methods in cutting movements was developed.<\/p>\n
Return-to-sport tests after ACLR should include a qualitative assessment of knee valgus during a cutting or change of direction task.<\/p>\n
Future studies should continue exploring RTS test criteria, specifically qualitative assessment, that predict second ACL injury risk with a bigger sample size, especially in young female population.<\/p>\n
This study examined risk factor of second ACL injury with using quantitative and qualitative measures. A battery of the quantitative tests using such as limb symmetry index is common for RTS tests following ACLR. Hopefully, this study opens the door for a qualitative RTS test evaluation following ACLR.<\/p>\n
