“…According to Angelo et al, there was no statistically significant difference in BCW values between the ACL-injured and control groups [16]. The ACL is located in the intercondylar notch, and it can impinge in certain knee postures [17]. There has also been a link between intercondylar notch stenosis and an increased risk of an ACL tear in some studies [12], [18].…”

BACKGROUND: Anterior cruciate ligament (ACL) tear is a condition that has been linked to both short-term and long-term clinical outcomes and has an anatomical risk factor known as femorotibial joint morphometrics. There are three grades of this condition, which are sometimes difficult to detect through imaging. AIM: This study aimed to analyze the prevalent ratio (PR) of femorotibial joint morphometrics to ACL tear grades using magnetic resonance imaging (MRI). METHODS: An observational approach along with a cross-sectional design was employed. The ACL tear grade and measurement of bi-intercondylar width (BCW), North width (NW), NW index (NWI), tibial plateau slope (TPS), tibial plateau depth (TPD), tibial eminence width (EW), and tibial EW index (EWI) were retrospectively evaluated in 48 patients using knee MRI with new non-contact ACL tear aged above 18 years. The Chi-square test was the statistical analysis used to measure PR. RESULTS: The number of subjects presented with ACL tear grade I-II and III was 16 and 32, respectively. The PR value of lateral TPS to ACL tear grades and the lowest 95% confidence interval (CI) were both greater than one, and hence, significant. However, the PR values of BCW, NW, NWI, and medial TPS to ACL tear grades were greater than one, but the lowest 95% CI was less than one, and hence, not significant. Finally, the PR values of TPD, EW, and EWI could not be determined in this study. CONCLUSION: The lateral TPS had a PR value greater than one, indicating that it is considered a risk factor for ACL tear grade III.

“…As a result, decreased volumes of the MTE may lead to less bony contact with the notch, placing greater demand on ligamentous restraints and other soft tissues, such as the menisci. 15 26 27 In the setting of an ACL-insufficient knee, the MTE seems to play a larger role in tibiofemoral stability, with lower MTE volumes being correlated with increased anterior tibial translation. 15 Therefore, while ACL injuries in young patients are often treated operatively, in a subgroup of older individuals with decreased posterior tibial slopes, large MTE dimensions, and no excessive anteroposterior laxity, the increased tibiofemoral stability resulting from these geometric factors may permit successful nonoperative management.…”

Anterior cruciate ligament (ACL) injuries commonly lead to translational and rotational tibiofemoral instability. The morphology of the medial tibial eminence (MTE) has received increased attention regarding its role in tibiofemoral stability in ACL-injured knees. Therefore, quantification of MTE dimensions on clinical imaging may help clinicians predict knee stability after ACL injury. Although magnetic resonance imaging (MRI) is routinely obtained in patients with ACL injuries, whether the dimensions of the MTE can be accurate quantified on MRI is unknown. The purpose of this study was to assess the degree of correlation between measurements of MTE height and width on computed tomography (CT) versus MRI. An institutional picture archiving and communication system imaging database was used to identify patients aged between 15 and 60 years who received concurrent MRI and CT of the same knee within a 1-year interval. Knees with significant arthrosis, deformity, intraarticular fracture, or hardware-related artifact that obscured visualization of the MTE were excluded. Mean differences and interstudy agreement between CT and MRI MTE measurements were compared using concordance correlation coefficient (r c) and Bland–Altman analysis. A total of 41 knees in 38 patients (mean age, 37 years; 82% male) were analyzed. Interrater reliability for CT and MRI measurements was high (intraclass correlation coefficient = 0.740–0.954). On coronal CT and MRI, mean MTE height measurements were 10.4 ± 1.9 and 10.4 ± 1.8 mm, respectively; mean MTE width measurements were 14.6 ± 3.6 and 14.2 ± 3.0 mm, respectively. On sagittal CT and MRI, mean MTE height measurements were 11.6 ± 1.7 and 11.7 ± 1.7 mm, respectively; mean MTE width measurements were 36.5 ± 4.8 and 36.2 ± 5.0 mm, respectively. Good agreement was observed between CT and MRI measurements of MTE height and width on coronal and sagittal planes (r c = 0.947–0.969). Measurements of MTE height and width were similar on MRI relative to CT on both coronal and sagittal planes. MRI may be suitable for characterizing the dimensions of the MTE when clinically evaluating patients with ACL injuries, potentially allowing for individualized patient care.

“…The studies of the tibia were also performed on radiographs. It has even been hypothesized that the width of EW may prevent ACL injuries (Li et al, 2020). The study aimed to determine the gender differences in the parameters bicondylar width (BCW), NW, NWI, tibia width (TW), EW, and EWI using dry bones from the same individuals.…”

Objectives: This study aims to determine the differences between the genders by measuring the anterior cruciate ligament (ACL) related bony structures on femur and tibia which are belongs to same individuals. To best our knowledge, the bony structures related with the ACL of the femur and tibia have never been investigated combined on dry bones in the literature. Materials and Methods: The study included 219 bones [108 femurs (74 male/34 female) / 111 tibias (72 male/39 female)]. Femur bicondylar width (BCW), intercondylar notch width (NW), tibial width (TW), tibial eminence width (EW) measured with a manual caliper. Intercondylar notch width index (NWI), and tibial eminence width index (EWI) also calculated. Results: In this study, the BCW, NW, NWI parameters were determined to be 65.90±3.23, 20.91±2.39, 0.31±0.03 in females, and 75.08±3.96, 23.45±2.80, 0.30±0.03 mm in males, respectively. The TW, EW, EWI parameters were determined to be 66.05±5.83, 8.89±1.48, 0.13±0.02 in females and 75.74±4.29, 11.02±1.96, 0.14±0.02 mm in males, respectively. Conclusions: In studying the structures associated with the ACL, it was found that there are morphological differences between the genders, which is an anatomically unavoidable situation. Also, the femur and tibia structures are statistically significantly correlated, we believe it would be more accurate to look for answers to ACL injuries by studying the two bones together.
