The α angle was lower in patients with ACL-injured group than in control group but it was not statistically different (41.9 º ±2.79 ºvs 42.06 º ±2.53 º; p= 0.978).Conclusion: This study showed that however low NWI, NA values are a risk factor for ACL injury, the strongest predictive factor was stenotic femoral notch type A. α angle had no significant correlation in ACL injury.

🎯
Objective & Hypothesis:Aim: The objective of the present study was to evaluate the femoral notch type, notch width index (NWI), notch angle (NA) and α angle in patients with ACL injury and compare with nonathletic male population, using magnetic resonance imaging (MRI).Methods: 79 patients with complete ACL tear and 80 patients as control group (aged 19-43 years) who had knee MRI were evaluated.
📊
Key Findings & Data:NWI, NA measurements and notch shape were evaluated on axial fat-saturated proton-weighted sequences.

Abstract

Aim: The objective of the present study was to evaluate the femoral notch type, notch width index (NWI), notch angle (NA) and α angle in patients with ACL injury and compare with nonathletic male population, using magnetic resonance imaging (MRI).Methods: 79 patients with complete ACL tear and 80 patients as control group (aged 19-43 years) who had knee MRI were evaluated. NWI, NA measurements and notch shape were evaluated on axial fat-saturated proton-weighted sequences. Femoral notch shape was classified as A, U and W types.Results: A statistically significant association was found between notch type, NWI, NA and ACL injury (p<0,001). Type A notch in the ACL-injured group (79.75 %) was significantly higher than the control group (24%). NWI was lower in patients with ACL-injured group than in control group (0.249 ± 0.020 vs 0.281 ± 0.022) Notch angle was lower in patients with ACL-injured group than in control group (47.15 º ± 5.63 º vs 50.73 º ± 5.44º). A significant association between stenotic notch type A and NWI (p <0,001). The α angle was lower in patients with ACL-injured group than in control group but it was not statistically different (41.9 º ±2.79 ºvs 42.06 º ±2.53 º; p= 0.978).Conclusion: This study showed that however low NWI, NA values are a risk factor for ACL injury, the strongest predictive factor was stenotic femoral notch type A. α angle had no significant correlation in ACL injury.

Özet

Amaç: Bu çalışmanın amacı, sporcu olmayan, erkek, ön çapraz bağ (ÖÇB) yaralanmalı hastalarda femoral çentik tipi, çentik genişlik indeksi (NWI), çentik açısı (NA) ve α açısını manyetik rezonans görüntüleme (MRI) kullanarak değerlendirmek ve karşılaştırmaktır.Yöntemler: Komplet ÖÇB yırtığı olan 79 hastanın ve 80 hastalık kontrol grubunun (19-43 yaş arası) diz MRI görüntüleri değerlendirildi. NWI, NA ölçümleri ve çentik şekli, eksenel yağa doymuş proton ağırlıklı sekanslar üzerinden değerlendirildi. Femoral çentik şekli A, U ve W tipleri olarak sınıflandırıldı.Bulgular: Çentik tipi, NWI, NA ve ACL yaralanması arasında istatistiksel olarak anlamlı bir ilişki bulundu (p<0,001). ÖÇB yaralanmalı grupta; A tipi çentik (%79.75), kontrol grubundan (%24) önemli ölçüde daha yüksekti. ÖÇB hasarlı grupta NWI kontrol grubuna göre daha düşüktü (0.249 ± 0.020 vs 0.281 ± 0.022). Çentik açısı ÖÇB hasarlı grupta kontrol grubuna göre daha düşüktü (47.15 º ± 5.63 º vs 50.73 º ± 5.44º). Stenotik çentik tipi A ile NWI arasında anlamlı bir ilişki mevcut idi (p <0,001). ÖÇB yaralanmalı hastalarda α açısı kontrol grubuna göre daha düşüktü ancak istatistiksel olarak fark yoktu (41.9 º ±2.79 ºvs 42.06 º ±2.53 º; p= 0.978).Sonuç: Bu çalışma, düşük NWI, NA değerlerinin ÖÇB yaralanması için bir risk faktörü gibi görünse de, en güçlü prediktif faktörün stenotik femoral çentik tip A olduğunu göstermiştir. α açısı ÖÇB yaralanmasında anlamlı bir korelasyon göstermemiştir.
