Notch morphology is a risk factor for ACL injury: a systematic review and meta-analysis

Profile of Knee MRI Morphometric Risk Factors for Anterior Cruciate Ligament Tear at Dr. Soetomo General Academic Hospital

“…This finding is consistent with a study from Han et al, Andrade et al, Zeh et al, Shen et al, Volkan et al, Huang et al, Bayer et al, Priono et al study, where they reported a significant correlation between an increase in MTPS value with ACL tear incidence. 2,[9][10][11]13,15,18,26 They also found that the case group had a mean MTPS value of more than 14.4 degrees. 8 Between total and partial tear groups, it was found that NW, NWI, Q-angle and MTPS values were smaller in total tear group than in partial tear group.…”

“…In a systematic review study by Bayer et al, Domzalski et al, Shaw et al, Zeh et al, Volkan et al, the NWI value was also referred to as an important factor for ACL tear evaluation..The NWI cut off value stated in Shen et al study for NWI was 0.25. 1,[9][10][11]16,1818 The case group had a larger -angle value with a mean value of 37.98±4.69 than the control group, with a mean value of 35.59±4.52. This result was consistent with previous studies results, which found that the case group had a mean -angle value of more than 38.5 degrees 15 , 60 degrees 18 , and 70 degrees 25 , which were greater than the control group.…”

“…NW and NWI value was assumed to be valuable for estimating ACL volume and could indicate impingement in ACL. 1,[9][10][11]15,16 The hypothesis in a study from Bining et al stated that the smaller the intercondylar notch, the greater the force imposed on the ACL midsubstance, which will increase the risk of injury. 24 In this study, mean NW for non-ACL tear group was higher ACL tear group.…”

“…Identification of these risk factors in athletes will be useful to adjust the type of training for each individual according to their anatomical variation for minimizing ACL tear incidence. 1,7,[9][10][11][12][13][14] Previous study reported that anatomical factors that play some roles in ACL tear were femurotibial alignment, narrow intercondylar notch, type A stenotic notch, medial tibial plate depth, and steep lateral tibial slope. However, various measurement techniques and methods of these anatomical factors are still debatable.…”

“…However, various measurement techniques and methods of these anatomical factors are still debatable. 1,2,[9][10][11]13,[15][16][17]18 This study aims to provide an overview of anatomical risk factor characteristics in knee joint MRI study.…”
