“…Although limited, there are publications in the literature revealing that the eminence structure is a risk factor for both ACL ruptures and avulsions of the tibial eminence. 23,25 In the present study, no relationship was found between the parameters defined and ACL rupture.…”

“…Eminence height was calculated as the perpendicular distance between the line connecting the lowest parts of the articular surface of both tibial condyles and the highest point of eminentia. 23 Medial, lateral, and overall eminence height were recorded separately. Based on the line connecting the medial plateau and lateral plateau joint lines (the line connecting the lowest parts of the articular surface of both tibial condyles), the tibial plateau surface was determined on the coronal MRI, and the distance between the highest points of the medial and lateral eminence was calculated in the same plane.…”

Background: There are no definitive anatomic morphometric risk factors for adolescent anterior cruciate ligament (ACL) injury. Purpose: To compare the parameters used to define the tibial and femoral morphometric structure of the knee between adolescent patients with and without ACL rupture. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Included were magnetic resonance imaging (MRI) scans and radiographs of 115 patients aged 10 to 17 years who were evaluated for ACL rupture at a single institution between February 1, 2019, and January 31, 2022. Images from 115 patients with intact MRI scans were included as controls. We investigated the following imaging parameters: tibial slope (on lateral radiograph), lateral condylar height, tibial sulcus height, medial condylar height, condylar width, intercondylar notch with, intercondylar notch angle, notch index, eminence width, tibial plateau width, eminence width/tibial plateau width, medial/lateral/overall eminence height, medial plateau depth, and 2 different eminence angles. Parameters were compared between groups using the chi-square, Fisher exact, Student t, or Mann-Whitney U test, as appropriate. Receiver operating characteristic analysis was conducted for cutoff values of significant parameters. Results: There were no significant differences in age, sex, or side affected between groups. Only the medial plateau depth was found to be statistically significant between the ACL rupture and ACL intact groups (2.6 vs 2.2 mm; P = .015). A statistically significant cutoff value could not be obtained for the medial plateau depth. Conclusion: Medial plateau depth was found to be significantly greater in adolescent patients with ACL rupture compared with ACL-intact controls.

“…Aging alters the morphology of the knee joint (Figure 6A–D ). From the age of three to 17 years the NWI grows smaller, from 0.326 in the youngest to 0.25 in the eldest (Anderson et al, 2001 ; Domzalski et al, 2015 ; Herzog et al, 1994 ; Lima et al, 2020 ; Pekala et al, 2019 ). Everhart et al ( 2014 ) also described a positive age‐related change in the size of the anteromedial ridge at the osteochondral border of the notch.…”

The intercondylar fossa—A narrative review

2021

View full text Add to dashboard Cite

The intercondylar fossa ("intercondylar notch," IN) is a groove at the distal end of the femur, housing important stabilizing structures: cruciate ligaments and meniscofemoral ligaments. As the risk for injury to these structures correlates with changes to the IN, exact knowledge of its morphology, possible physiological and pathological changes and different approaches for evaluating it are important. The divergent ways of assessing the IN and the corresponding measurement methods have led to various descriptions of its possible shapes. Ridges at the medial and lateral wall are considered clinically important because they can help with orientation during arthroscopy, whereas ridges at the osteochondral border could affect the risk of ligament injury. Changes related to aging and sex differences have been documented, further emphasizing the importance of individual assessment of the knee joint. Overall, it is of the utmost importance to remember the interactions between the osseous housing and the structures within.

“…Previous studies reported several morphological risk factors for primary ACL ruptures in children and adolescents [6–8, 22, 32]. Risk factors in children include an increased medial and lateral tibial slope, narrower notch width, increased size of tibial eminence and patella alta [6–8, 22, 32]. The tibial slope has been studied previously as a morphological risk factor for re‐ruptures or revisions in children and adolescents [5, 12, 26].…”
