Abstract Background:Overuse injuries and ankle sprains are commonly sustained by soldiers and athletes during conditioning programs and may have significant ramifications on both individuals and organizations. The Landing Error Scoring System (LESS), and its expedited real-time version (LESS-RT) were developed to assess risk for ACL injuries, but have never been used to assess overuse or ankle injuries which are of high priority in a military or athletic settings. The purpose of this study was to evaluate predictive value of The Landing Error Scoring System Real-Time (LESS-RT) for overuse injuries of the lower limb and ankle sprains among Israel Defense Forces (IDF) combat soldiers.Methods: A historical cohort study was conducted on 2,474 IDF combat soldiers from different service units with a wide range of fitness levels and training requirements. The predictive variable was LESS-RT score and the outcome variables were the incidence of overuse injuries and ankle sprains. Receiver operator characteristic curves were used to assess the predictive value of LESS-RT for both outcomes. Results: The AUC for overuse injuries and ankle sprains were 0.537, 95% CI 0.514-0.560 and 0.523, 95% CI 0.491-0.556 respectively. Conclusions:The results of this study shows no predictive value of LESS-RT score for both overuse injuries of the lower limb and ankle sprains.

Abstract Introduction The high frequency and number of ankle inversion injuries and meniscal injuries in military populations is an area of concern due to the debilitating effects and cumulative consequences of these particular injuries on the soldiers sustaining injury and the consequences on the operational effectiveness of the Israeli Defense Force (IDF). This study examines the possible relationship between ankle inversion injury and potential for subsequent meniscal injury in infantry soldiers in the IDF. Material and Methods All 89,069 infantry combat soldiers (including special units), recruited to the IDF between 2007 and 2017 were included in this study. A historical cohort study was conducted. The cohort was divided into two groups: The exposure group included all participants that had suffered at least one ankle sprain in the past and the unexposed group that included all participants who did not suffer an ankle sprain in the past. A Cox proportional-hazards model (COX) model was used in order to obtain the adjusted to confounders association between exposure and outcome expressed in hazard ratio (HR). Results The crude association between ankle sprain in the past and the development of meniscal injury in this study was 0.87 (Relative risk = 0.87, P = 0.007). After adjusting for unit type, Body Mass Index (BMI), previous fracture of the lower limb, and the use of eyeglasses, using a COX model, the adjusted association between ankle sprain in the past and the development of meniscal injury was 0.8 (HR = 0.8, P = 0.001, confidence interval (95%) 0.74, 0.88). Conclusion The results of this study indicate ankle sprains to be a protective factor for meniscal injury. Our main conclusion from the results of this study is that the assumption that those with previous leg injuries are at a greater risk for further leg injuries is questionable and cannot be generalized. Hence, the association between different types of injuries should be investigated separately.
