Abstract

Objective: The knee joint is an articulation exposed to excessive load during daily activities at all ages. There are ongoing discussions about the suitability of the currently used standard implants for this joint in terms of age and gender. In our study, we aimed to determine the possible morphometric differences of the bone structures involved in this joint according to age groups and gender.
Materials and Methods: The magnetic resonance (MR) images of the knee joints of 212 individuals (106 males, 106 females) aged between 18 and 69 years were retrospectively analyzed, and morphometric data were obtained from these images. Patients were separated according to age groups and gender, and the obtained data were analyzed.
Results: In the study, the measurement values related to the morphology of the femur, tibia, patella, and patellar ligament were generally higher in males than in females (p<0.05). When evaluated separately by sex, statistically significant differences were observed in certain morphometric parameters among the age groups (p<0.05).
Conclusions: Our study has shown that human knee anatomy varies significantly according to age and gender. These differences should be considered in the design of individualized and gender-specific knee joint prostheses.

Yaş ve Cinsiyete Göre Diz Morfolojisindeki Farklılıklar: MRG Üzerinden Yapılan Bir Değerlendirme

Abstract

Amaç: Diz eklemi günlük aktiviteler sırasında her yaşta aşırı yüke maruz kalan bir eklemdir. Günümüzde bu ekleme uygulanan mevcut standart implantların yaşa ve cinsiyete uygunluğu ile ilgili tartışmalar devam etmektedir. Biz de çalışmamızda bu ekleme katılan kemik yapıların yaş gruplarına ve cinsiyete göre olası morfometrik farklılıklarının belirlenmesini amaçladık.
Materyal ve Metot: 18-69 yaş aralığındaki 212 kişiye (106 erkek, 106 kadın) ait diz manyetik rezonans (MR) görüntüleri retrospektif olarak incelenerek bu görüntüler üzerinden morfometrik veriler elde edildi. Hastalar yaş gruplarına ve cinsiyete göre ayrılarak elde edilen veriler analiz edildi.
Bulgular: Çalışmada, femur, tibia, patella ve patellar ligamentin morfolojisi ile ilgili ölçüm değerleri genel olarak erkeklerde kadınlardan daha yüksek bulundu (p<0,05). Cinsiyetler ayrı olarak değerlendirildiğinde, yaş grupları arasında bazı morfometrik parametrelerde istatistiksel olarak anlamlı farklılıklar tespit edildi (p<0,05).
Sonuç: Çalışmamızda insan diz anatomisinin yaşa ve cinsiyete göre önemli farklılıklar içerdiği gösterilmiştir. Bu farklılıklar bireysel ve cinsiyete özgü diz eklemi protezi tasarımı çalışmalarında dikkate alınmalıdır.
