Morphometric parameters as risk factors for anterior cruciate ligament injuries: A MRI case-control study

Abstract

According to the results of our study we can say that a narrow intercondylar notch contains a proportionally thin anterior cruciate ligament, but we cannot say that this factor necessarily leads to rupture of the anterior cruciate ligament.

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

“…Conversely, Alentorn-Geli et al ,19 Stijak et al 7 and Lombardo et al 18 found no significant difference on ICN width between ACL-injured and non-ACL-injured participants. Similarly, Vrooijink et al 12 found no significant difference on the ICN width between ACL-injured and non-injured participants; however, they found smaller bicondylar width in injured male participants.…”

“…The meta-analysis performed confirms this association, showing that ACL-injured patients had significantly narrower ICN widths when compared to those who were non-injured. In contrast, three studies were not able to show the same results 7 18 19. Lombardo et al 's18 was the only study in which the authors measured ICN width at 45° of knee flexion on X-rays instead of, as all the other studies did, on MRIs.…”

“…The majority of the studies used MRI7–17 19–21 23 24 or radiography7 18 21–23 25–29 for measurement of bone morphology parameters. Additionally, Vrooijink et al 12 compared their measurements performed by MRI or intraoperatively, which did not find any correlation.…”

“…In addition, one study performed a case-series of ACL-reconstructed and ACL-deficient patients 25. Overall, the studies provided a moderate description of their inclusion and exclusion criteria: 11 studies included isolated unilateral ACL tears,7 9 11 13 16 20–26 7 studies included ACL reconstruction/surgery patients,8 10 12 15 19 27 28 one study explored ACL-deficient knees,29 one study investigated the contralateral knee of ACL-injured patients17 and one study also included bilateral ACL tears 23. Nonetheless, 12 of 23 studies (52%)7–10 12 13 15–17 20 23 25 did not report how did they determined the status of ACL.…”

Intercondylar Notch Stenosis of Knee Osteoarthritis and Relationship between Stenosis and Osteoarthritis Complicated with Anterior Cruciate Ligament Injury

“…4,8 The reason of ACL injury caused by the intercondylar notch stenosis is variable. Stijak et al 23 and Dienst et al 24 , as per their research work, think that the ACL's cross-sectional area was small, strength was weak, biological performance was poor and easy to injury in intercondylar notch stenosis patients. Everhart et al 25 found that in the knee joint movement, ACL can collide with the stenotic intercondylar notch, resulting to wear and tear and finally lead to ACL injury.…”
