研究概览
简要总结
The aim of this study is to evaluate the posterior condylar angle of the distal femur in Turkish population and its concordance with the current standard prosthesis designs used in total knee arthroplasty and to evaluate anthropometric features of the distal femur in the Turkish population.
详细描述
The investigators would like to measure condylar twist angles(CTA), posterior condylar angles(PCA), femoral mediolateral lengths (fML), medial femoral anteroposterior lengths(fMAP), lateral femoral anteroposterior lengths (fLAP), distances between trochlear groove and fMAP(DBTG-fMAP), distances between trochlear groove and fLAP(DBTG-fLAP), medial and lateral posterior condylar cartilage thicknesses(MPCCT/LPCCT) on the Magnetic Resonance Images (MRI) of 240 knees of 120 Turkish subjects.

结局指标
主要结局
condylar twist angle and posterior condylar angle
时间窗: about 5 days
The condylar twist angle (CTA) is an angle between anatomical transepicondylar axis (TEA),which lying from medial epicondyle to lateral epicondyle of the distal femur, and posterior condylar axis (PCAx). The posterior condylar angle (PCA) is an angle between surgical TEA, which lying from medial epicondylar sulcus to lateral epicondyle, and PCAx\[1\].
次要结局
- Medial and lateral posterior condylar cartilage thicknesses (MPCCT/LPCCT)(about 5 day)
- mediolateral lenght of the distal femur (fML)(about 5 days)
- Distance between trochlear groove and fMAP (DBTG-fMAP) and distance between trochlear groove and lateral fAP(DBTG- fLAP)(about 5 days)
- medial anteroposterior lengt (fMAP) and lateral anteroposterior lengt (fLAP)(about 5 days)
