Abstract

Amaç: Bu çalışmada lateral patellar kartilaj defektli hastalar ile yaş-taraf eşleştirilmesi yapılmış kartilaj lezyonu olmayan kontrol hastaları arasında manyetik rezonans görüntüleme (MRG) ile gözlenen troklear morfolojiyi karşılaştırmayı amaçladık.
Yöntem : MRG ile tanımlanan grade 3/4 lateral patellar kartilaj defektli toplam 75 hasta patellofemoral eklemde kartilaj defekti olmayan yaş-taraf eşleştirilmiş kontrol hastaları ile karşılaştırıldı. Aksiyal kesitler patellar kartilaj defektini saptamada kullanıldı. Troklear morfoloji lateral troklear inklinasyon ( LTI) , medial troklear inklinasyon ( MTI), sulkus açısı (SA) , troklear faset asimetrisi (FA) ve troklear genişlik (TG) ile aksiyel kesitlerde değerlendirildi.
Bulgular : SA kontrol grubu ile karşılaştırıldığında her iki cinsiyet için defekt grubunda büyüktü (p < 0.05). Kartilaj defekt grubunda LTI kontrol grubu ile karşılaştırıldığında , özellikle kadınlarda belirgin olmak üzere ,düşüktü (p < 0.05). Her iki cinsiyet için her iki grup arasında MTI 'da istatistiksel olarak anlamlı fark bulunmadı (p > 0.05). Her iki cinsiyet için kartilaj defekt grubunda FA kontrol grubu ile karşılaştırıldığında düşük idi(p < 0.05). TG kontrol grubu ile karşılaştırıldığında defekt grubunda büyüktü (p < 0.05). Ayrıca,kartilaj defekt grubundaki kadınlarda TG kontrol grubundan büyüktü (p < 0.05).
Sonuç: Düzleşmiş lateral troklea özellikle kadınlarda lateral patellofemoral eklemde kartilajda yapısal zedelenme için risk faktörüdür.

Relationship between trochlear morphology and lateral patellar cartilage defect using MR Imaging

Abstract

Aim: The present study aimed to compare trochlear morphology observed on magnetic resonance imaging (MRI) between patients with lateral patellar cartilage defect and age-matched-pair control patients without cartilage defect.
Methods: A total of 75 patients with MRI-verified grade 3/4 lateral patellar cartilage defect were compared with matched-pair control patients without cartilage defects of the patellofemoral joints. Axial sequences were used to detect and evaluate patellar cartilage defects. Trochlear morphology was assessed on the basis of lateral trochlear inclination (LTI), medial trochlear inclination (MTI), sulcus angle (SA), trochlear facet asymmetry (FA), and trochlear width (TW) on axial MR images.
Results: SA was higher for both sexes in the cartilage defect group than in the control group (p < 0.05). LTI of the cartilage defect group was significantly lower than that of the control group, particularly in females (p < 0.05). There were no significant differences in MTI between the two groups for either sex (p > 0.05). FA for both sexes was significantly lower in the cartilage defect group than in the control group (p < 0.05). TW was significantly higher in the cartilage defect group than in the control group (p < 0.05). Finally, TW of females in the cartilage defect group was significantly higher than that of females in the control group (p < 0.05).
Conclusion: Flattened lateral trochlea is a risk factor for structural damage to the cartilage of the lateral patellofemoral joint, particularly in females.
