Correlation Between Anatomical Parameters Of Femoral Condyle,Posterior Inclination Of Tibial Plateau And Injury Of Anterior Cruciate Ligament:A Meta-Analysis

Objective:This article adopts the method of Rev Man 5.3 software system evaluation,to explore the relationship between the anatomical parameters of femoral condyle and the posterior inclination of tibial plateau and anterior cruciate ligament(ACL)injury,Analyze and seek out the main risk factors of anterior cruciate ligament(ACL)injury.To provide theoretical basis and reference value for clinical prevention and treatment of anterior cruciate ligament(ACL)injury.Methods:Through the computer using Note Express software data engine,it receives five major databases such as Pub Med,Nature Journal,Web of Science,Chinese Journal Full Text(CNKI)database,and Wanfang database.The time frame of the search was from the establishment of the database to December 2020,and the national and international literature included articles on the anatomical parameters of the femoral condyles and the posterior tibial plateau inclination angle associated with ACL injuries,and contained controlled studies of case groups and healthy groups,and the Newcastle Ottawa Scales(NOS)criteria were used to evaluate the quality of the literature.Rev Man 5.3 software was used to perform Meta-analysis on the data collected from the literature.Results:A total of 54 studies were included in the analysis and evaluation,including 4616 cases of no injury of anterior cruciate ligament(ACL)and 3315 cases of injury of anterior cruciate ligament(ACL).Meta-analysis and evaluation results:(1)there was significant difference between ACL injury and intercondylar fossa width index(NWI)in coronal position(Z=7.91,P<0.001,MD=0.03,95%CI: 0.02～0.04)(2)there was a significant difference between the(ACL)injury of anterior cruciate ligament and the width of femoral intercondylar fossa in coronal position(Z=6.21,P<0.001,MD=2.66,95%CI:1.82～3.50).There was a statistically significant difference between the ACL injury and the width of intercondylar fossa of femur in axial position(Z=2.38,P=0.02,MD=1.23,95%CI : 0.22 ～ 2.24).(3)There was a statistically significant difference between the ACL injury and the posterior tibial slope(Z=2.24,P=0.03,MD=-1.11,95%CI:-2.09～-0.14).There was a statistically significant difference between the ACL injury and the Materal tibial slope(Z=4.3,P<0.001,OR=-0.79,95%CI:-1.15～-0.43).There was a statistically significant difference between ACL injury and the Lateral tibial slope(Z=4.89,P<0.001,MD=-1.94,95 % CI :-2.72 ～-1.17).(4)There was significant difference between ACL injury and intercondylar Shape Index(NSI)in coronal position(Z=2.44,P =0.01,SMD=2.31,95%CI: 0.45～4.16).There was significant difference between ACL injury and NSI in axial position(Z=7.65,P<0.001,MD=0.05,95%CI: 0.05～0.06).(5)there was significant difference between the ACL injury and Intercondylar Height(ICH)in coronal position(Z=2.05,P=0.04,MD=0.80,95%CI: 0.04～1.57).Conclusion:Meta-analysis showed that there was an association between intercondylar fossa width(coronal and transaxial),intercondylar fossa height(coronal),intercondylar fossa width index(coronal),intercondylar fossa morphology index(coronal and transaxial),and tibial plateau posterior tilt angle and ACL injury.Among them,intercondylar fossa width and intercondylar fossa morphology index of femur showed negative correlation with the data of ACL injury group,and the posterior tibial plateau inclination angle showed positive correlation with ACL injury group.
