“…According to Khodair et al, patients with lower North width (NW) and NW index (NWI) are more likely to sustain ACL injuries. However, there was no statistically significant difference in bi-intercondylar width (BCW) in males [8]. This is consistent with Shaw et al showing that the NWI in the ACL-injured group was lower than in the control group of immature patients [9].…”

“…The measurements of distal femoral morphometrics were based on Shaw et al's method and occurred in the coronal and sagittal planes [9]. The image selected for measurement was taken at the ACL's mid-substance and the point of decussation between the ACL and the posterior cruciate ligament (PCL) [8]. Subsequently, a line was drawn through the anatomical axis of the femur at the popliteal groove, parallel to a line drawn across the inferior border of both condyles.…”

“…The classification of the femorotibial morphometrics was based on a cutoff value in previous studies. NW was classified as <20 mm and ≥20 mm, whereas BCW was classified as <70 mm and ≥70 mm [8]. NWI was classified as <0.25 and ≥0.2, whereas MTPS and LTPS were classified as >7° and ≤7° [9], [14].…”

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.

“…A study by Khodair et al showed significant differences in distal femur morphology, in particular notch width and NWI in ACL injured and noninjured in both males and females. [15] NWI in injured knees was observed to be 0.22 ± 0.008 by Görmeli et al [16] Our study showed a much higher mean NWI.…”

Introduction: Injuries to the anterior cruciate ligament (ACL) are commonly encountered in day-to-day practice. The morphology of the intercondylar notch (ICN), in particular, the width, and shape of the notch are of anatomic interest predisposing to ligament injuries. The previous literature points to contradicting views on the association between ICN dimensions and cruciate ligament injuries. Aim of the study: This study aims to study the morphometry of the ACL and ICN in 32 prosected lower limbs and to see if any association exists between the two. Objectives The objectives of the study were to estimate the dimensions of ACL (maximum length and width) in 32 prosected lower limbs, estimate the dimensions of ICN (ICN width and depth) along with intercondylar (IC) width in 32 prosected lower limbs, and test the strength of association between the dimensions of ICN with the dimensions of ACL. Materials and Methods: The study was done in the Department of Anatomy of MVJ Medical College and Research Hospital, Bengaluru. Thirty-two prosected lower limbs from the department of anatomy were used for the study. Results: It was observed that IC width correlated positively with ACL length as well as ACL width. A strong positive correlation was also observed between IC width with ICN width. Femoral notch width index also correlated positively with ACL width. Conclusions: The above study provides valuable data on the morphometry of ACL and its association with all dimensions of IC fossa unlike previous studies which have correlated the dimensions of IC fossa only with the thickness of ACL.

“…Patients with knee deformities or dysplasia, connective tissue or hematologic disorders, fractures involving articular surfaces, prior knee arthroscopy/surgery or osteoarthritis were excluded from the study. [12] The measurements were performed in the frontal plane in MR images, and in the horizontal plane in bone specimens. Therefore, we did not make a comparison between the bone and MRI samples.…”

Objectives: Distal femur anthropometric indices are the main parameters for the design of knee implants. However, there are several variations concerning the anatomy and congruence of the distal femur in different populations. The purpose of this study was to identify anthropometric data on the distal femur and investigate the correlation between the trochlear line -epicondylar line angle and intercondylar notch width index in an Iranian population.Methods: Distal femur measurements were performed in 158 knees on bony specimens and 187 MRIs from an Iranian population. Intercondylar width, intercondylar notch width, and trochlear line -epicondylar line angle were measured and intercondylar notch width index was calculated. Results:In bony specimens, the trochlear line -epicondylar line angle was measured as 7.38° and intercondylar notch width as 19.36 mm. In MRI images, the trochlear line -epicondylar line angle was measured as 6.07° and notch width index as 0.276 mm. Linear regression analysis showed a significant relationship between the trochlear line -epicondylar line angle and notch width index (p<0.05). Conclusion:The results of this study provide fundamental data for the design of knee prostheses suitable for the Iranian population.
