Anatomical Parameters

INTRODUCTION: Frequency of anterior cruciate ligament rupture depends of anatomical parameters of distal femur and intercondylar notch. PURPOSE: Purpose of this work is identification relation between femur length and morphometrical parameters intecondylar notch, measuring in two levels. METHOD: A hundred femur's (medley population of 48 right and 52 left femurs), from osteological collection Department of Anatomy 'dr. Niko Miljanic' in Belgrade measured. Measurement was in two levels. Epicondilar width, width of medial and lateral condyls and intercondylar width, had been measured in level of popliteal sulcus and on the widest place, after that notch width index had been determinated. RESULTS: Absolute values of morphometrical parameters distal femur's are in positive relation with her length (p <0.01), but notch width index is not, as in level of popliteal sulcus, as on the widest place (p>0.05). CONCLUSION: Femur's length increasing also produces increasing of absolute anatomical parameters of distal femur which can produce rupture of anterior cruciate ligament, while relative dimensions do not show femur's length increasing.

Purpose. To compare anatomic lower limb features of anterior cruciate ligament (ACL)–deficient versus –intact knees in Chinese subjects. Methods. Anatomic lower limb features (mechanical axis, tibiofemoral angle, posterior tibial slope, notch width index, and hip neck-shaft angle) of 25 men and 3 women aged 18 to 39 (mean, 26) years with ACL-deficient knees, and 16 men and 4 women aged 24 to 31 (mean, 28) years with ACL-intact knees were compared using radiography. Results. The notch width index (0.26 vs. 0.29, p=0.02) was significantly smaller in ACL-deficient than ACL-intact knees. Conclusion. Small notch width was associated with a thin ACL and can be regarded as an anatomic intrinsic risk factor for ACL injuries.

AbstractThe presentation and clinical course of mucoid degeneration of the anterior cruciate ligament (MD-ACL) are poorly documented within the literature. Subsequently, it is under-diagnosed and the optimal management strategy remains ill-defined. Here, we characterize the syndrome associated with MD-ACL and compare the natural clinical course with the outcomes of arthroscopic management. Thirty-one patients with radiological features of MD-ACL over a 2-year period had their clinical notes retrospectively reviewed. Seven patients underwent arthroscopic debridement of the ACL for MD. These were followed up for a minimum of 2 years and an average of 2.8 years from surgery. The remainder were managed conservatively (n = 24) and were followed up for a minimum of 2 years and an average of 4.0 years. The notch width index (NWI) and associated pathology was noted. Primary outcome measures were presence of knee pain and use of analgesia. Secondary outcome measures were the Oxford and Lysholm knee scores. The most commonly reported symptoms were posterior knee pain (77.4%) and limitation of terminal flexion (58.1%). All patients who underwent arthroscopic debridement were pain and analgesia free at follow-up. Of the patients who did not undergo arthroscopic surgery, three patients had knee replacement surgery and three were lost to follow-up. The remaining patients, 14/18 (77.8%), reported knee pain and regular analgesia use at follow-up, which was significantly more than the arthroscopic debridement group (p < 0.01). The knee scores were significantly better in the arthroscopic debridement group at follow-up (Oxford knee score: 45 vs 34; Lysholm: 92 vs 67; p < 0.01). Furthermore, the postoperative improvement in the Oxford knee and Lysholm scores compared with preoperatively was 12.1 and 31.8 points, respectively (p < 0.01). The NWI was increased in patients with mild-to-severe osteoarthritis (0.266 vs 0.273; p < 0.05). MD-ACL should be considered in patients who report posterior knee pain, limitation of terminal flexion, and it can be associated with other knee pathologies. MD-ACL can be successfully managed with arthroscopic radio frequency debulking with improvement in quality of life at follow-up.

Background: Anterior cruciate ligament is one of the commonly injured ligaments in knee. The shape and dimension of the femoral notch has been linked with the risk of anterior cruciate ligament injury. The aim of this study was to study the risk of Anterior cruciate ligament injury with notch morphology in the Nepalese population.Methods: This study is a case control study. Cases undergoing arthroscopic surgery at 2 tertiary level centers were enrolled. Patients with arthroscopic confirmation of Anterior cruciate ligament tear were taken as case and those without tear were taken as control. Axial Magnetic resonance Imaging sequence was used to study notch. Sections at the level of popliteal groove was taken for study and shapes were identified as A, U and W type, and notch width index was calculated. These variables were correlated with presence or absence of Anterior cruciate ligament tear.Results: Out of 118 cases, 59 had tear, and 59 had no tear. Tear was found in 74% of Type A notch compared to 30.15% in Type U notch. The femoral notch width index was low in 42.59% of A type notch patients compared to 20.63% with U type notch. Analysis of notch width index among patients with Anterior cruciate ligament tears, showed that 40.67% of Anterior cruciate ligament torn knee had narrow notch compared to 22% in non- injured group, which was statistically significant.Conclusions: Type A notch and narrow notch both are risk factors for Anterior cruciate ligament tear.Keywords: Anterior cruciate ligament; injury; notch.

Background: The relationship between anterior cruciate ligament (ACL) injury and anatomical structures is still a topic of debate. Purpose: The aim of this study was to compare knee geometry in demographically matched ACL-injured and ACL-intact athletes. Methods: We conducted a case-control study comparing 2 groups, each consisting of 55 professional athletes (44 men and 11 women): 1 group with complete ACL tears (cases) and 1 group with intact ACLs (controls). The groups were compared using magnetic resonance imaging (MRI) in terms of intercondylar notch geometry, tibial plateau characteristics, and ACL volume. Results: Among cases and controls, we found the cases had lower notch width (20.24 ± 2.68 mm vs. 22.04 ± 2.56 mm, respectively) and notch width index (0.29 ± 0.03 vs. 0.31 ± 0.03, respectively). The mean ACL volume in the cases (1181.63 mm3 ± 326 mm3) was also lower than in controls (1352.61 mm3 ± 279.84 mm3). The parameters of tibial slope geometry were comparable between groups. In addition, women had lower ACL volume than men (1254 ± 310 mm3 vs. 890 ± 267 mm3, respectively) and higher medial posterior tibial slope (4.76 ± 2.6 vs. 6.63 ± 1.83, respectively). Among cases, women had narrower notch width than men (16.9 ± 2.42 mm vs. 21.08 ± 2.03 mm). However, notch width index was comparable between male (0.3 ± 0.02) and female (0.28 ± 0.03) cases. Conclusion: Our findings suggest that narrow notch width and low ACL volume may enhance the risk of ACL injury among athletes. There was no association found between posterior tibial slope and ACL injury between athletes with injured ACLs and controls. Further study is indicated.
