Abstract:
Objective To explore the incidence of global anterior tibial subluxation(ATS)after an-terior cruciate ligament(ACL)injury and analyze its risk factors.Methods The weight-bearing magnet-ic resonance imaging(MRI)scans of 280 consecutive patients with ACL injury in year 2022 and 2023 were retrospectively analyzed.According to the relative relationship between the tibial plateau and the femoral condyle,all patients were divided into three groups of the ATS-negative group(no ATS in neither the medial nor the lateral tibial plateau),the mild ATS-positive group(only ATS of the lateral tibial plateau),and the global ATS-positive group(ATS of both the medial and lateral tibi-al plateau).Moreover,the posterior tibial slope(PTS),the continuity of anterolateral ligament(ALL),the integrity of meniscus,the time from injury to surgery(TFIS)and results of physical ex-aminations were detected to find the risk factors of global ATS.Results Among the 280 consecutive pa-tients,41 patients were finally confirmed to have global AT,reaching an incidence of 14.6%.More-over,there were 110(39.3%)patients of mild ATS and 129(46.1%)without ATS.Meanwhile,the PTS,as well as the incidence of combined medial meniscus injury and TFIS of the global ATS-posi-tive group were significantly higher than the other two groups(P<0.05).In addition,the incidence of combined ALL and lateral meniscus injury,grade of pivot-shift test and KT-1000 side-to-side differ-ence of the global ATS-positive group were significantly higher than the ATS-negative group(P<0.05),without significant differences from the mild ATS-positive group(P>0.05).Furthermore,results of logistic multi-factor regression analysis showed that PTS>12 degrees,TFIS>6 months and combined medial meniscus injury were all independent risk factors of global ATS after ACL injury.Conclusion In this study,the incidence of global ATS after ACL injury was 14.6%.Clinically,ACL-injured pa-tients with PTS>12 degrees,TFIS>6 months or combined medial meniscus injury should be warned against the global ATS.
