A prospective evaluation of the Landing Error Scoring System (LESS) as a screening tool for anterior cruciate XXXX risk.

@entity1 @entity626 @entity130
BACKGROUND: Anterior cruciate ligament (ACL) injuries are immediately disabling, costly, take a significant amount of time to rehabilitate, and are associated with an increased risk of developing posttraumatic @entity626 . Specific multiplanar movement patterns of the lower extremity, such as those associated with the drop vertical jump (DVJ) test, have been shown to be associated with an increased risk of suffering noncontact @entity130 . The Landing Error Scoring System (LESS) has been developed as a tool that can be applied to identify individuals who display at-risk movement patterns during the DVJ. HYPOTHESIS: An increase in LESS score is associated with an increased risk of noncontact @entity130 . STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Over a 3-year interval, 5047 high school and college @entity1 performed preseason DVJ tests that were recorded using commercial video cameras. All @entity1 were followed for @entity130 during their sports season, and video data from injured @entity1 and matched controls were then assessed with the LESS. Conditional logistic regression analysis was used to examine the association between LESS score and @entity130 risk in all @entity1 as well as subgroups of female, male, high school, and college @entity1 . RESULTS: There was no relationship between the risk of suffering @entity130 and LESS score whether measured as a continuous or a categorical variable. This was the case for all @entity1 combined (odds ratio, 1.04 per unit increase in LESS score; 95% confidence interval, 0.80-1.35) as well as within each subgroup (odds ratio range, 0.99-1.14). CONCLUSION: The LESS did not predict @entity130 in our cohort of high school and college athletes.
