“…Because of the low prevalence of PCL avulsion fracture, screening only to determine the risk of sustaining a PCL avulsion fracture would likely not be cost e cient. However, several studies on the relationship between morphological measurements and traumatic diseases of the knee including ACL injury [6][7][8][9][10], ramp lesion of meniscus [11], and tibial spine avulsion fractures [12], PCL injury [13,14], have already been conducted, and more risk factors have been associated with knee-related sports injuries. All of these risk factors could be combined as a menu to nd and help patients at risk for different types of knee injury [13].…”

“…Nowadays, several studies on the relationship between morphological parameters and traumatic diseases of the knee have already been conducted. Many studies have found different relationships between measurements of knee geometry and anterior cruciate ligament (ACL) injury, such as stenotic intercondylar notch type [6], intercondylar notch volume [7], medial tibial slope [8], lateral tibial slope [9], and tibial slopes (both bony and meniscal) [10]. Similarly, Song et al reported that increased medial meniscal slope was associated with greater risk of ramp lesion of the meniscus in noncontact ACL injury [11].…”

Background Several studies on the relationship between morphological parameters and traumatic diseases of the knee have already been conducted. However, few studies focused on the association between knee morphology and posterior cruciate ligament (PCL) avulsion fracture in adults. The objective of this study was to evaluate the impact of knee morphology on PCL avulsion fracture and determine risk factors in men and women separately. Methods A retrospective case-control study of 48 patients (comprised 25 men and 23 women) with PCL avulsion fracture compared with 48 age- and sex-matched controls was performed from 2012 to 2018. MRI measurements of the knee were acquired in the sagittal, coronal, and axial sequences. The assessed measurements including intercondylar notch width index, medial/lateral posterior tibial slopes, and coronal tibial slope were compared between case and control groups in both women and men. Univariable and binary logistic regression analyses were used to identify independent risk factors that were associated with PCL avulsion fracture. Results When female patients were analyzed, the notch width index (coronal) was significantly smaller, and the lateral posterior tibial slope was significantly higher in the case group. The binary logistic regression analysis showed that the notch width index (coronal) (B = -0.307, OR = 0.735, p = 0.025) was found to be an independent factor. When male patients were analyzed, no radiographic parameter was found to have a statistical difference between the case and control groups. Conclusions Notch width index (coronal) and lateral posterior tibial slope were found to affect PCL avulsion fracture in women, but no such measurements affected the PCL avulsion fracture in men. Furthermore, a smaller notch width index (coronal) in women was found to be a risk factor in PCL avulsion fracture.

“…In this context, many surveys have determined a narrow intercondylar notch to be a risk factor for the ACL rupture in adults (Smith et al, 2012;Li et al, 2018;Shen et al, 2018;Taneja et al, 2018) and children (Dorizas and Stanitski, 2003;Domzalski et al, 2010). These studies were based on recent imaging methods, magnetic resonance imaging (MRI) in particular, due to the excellent image quality with no radiation exposure, which is crucial in the pediatric population (Bouras et al, 2018).…”

Differences in knee development result in morphological variations observed among individuals. Some of them predispose to significant knee injuries. Although the anatomical risk factors are well established in adults, there is still a need for further research in this area in the group of children. This work aims to determine the morphological variations of the intercondylar notch of the femur predisposing to anterior cruciate ligament (ACL) injuries in the pediatric population. Magnetic resonance imaging (MRI) scans of the knee were retrospectively analyzed in 74 patients aged 4–18 years. Examinations were performed due to pain complaints after trauma. The completely torn ACL was found in 35 patients. The diagnosis was confirmed intraoperatively. The remaining patients, with no signs of injuries, were qualified as a reference group. The intercondylar notch width was evaluated by calculating the Notch Width Index. Additionally, the morphology of the intercondylar eminence was assessed. Finally, a statistical analysis of the obtained data was performed.Patients with a torn ACL had a narrower intercondylar notch (a lower Notch Width Index, P = 0.0007) as well as a broader and more sharply ended intercondylar eminence (P = 0.0267 and 0.0188, respectively). The narrowed intercondylar notch, expressed by the low Notch Width Index, and the increased size of the intercondylar eminence were identified as the risk factors for the ACL rupture in children.

“…Many methods of notch size measurements on imaging have been described. 2,[8][9][10] However, most methods have been used to study the relationship of notch size to ACL injury, and few have tried to reproduce arthroscopic measurements. Zeng et al 11 performed a meta-analysis of 16 studies assessing the correlation between intercondylar notch size and the risk of ACL injury.…”

Small intercondylar notch size is associated with increased risk of anterior cruciate ligament (ACL) injuries and increased difficulty of ACL reconstruction. When encountering a small notch during surgery, some surgeons may resort to a notchplasty, which has been shown to have associated morbidity. The ability to predict notch size on preoperative imaging could allow the orthopaedic surgeon to anticipate surgical difficulty such as an oversized graft and graft impingement and possibly avoid a notchplasty. Many methods have been proposed for measuring intercondylar notch size, but they do not correlate with intraoperative measurements or they utilize computed tomography scanning, which is not readily obtained before ACL reconstruction. The purpose of this study was to develop a method of notch measurement on preoperative radiography and magnetic resonance imaging that match intraoperative arthroscopic measurements. The method presented here can be used to identify narrow intercondylar notches, prepare for potential intraoperative challenges, and formulate surgical plans such as for graft choice in individualized ACL reconstruction.
