AIM To measure this angle, we determine through the axes the transepicondylar axis (cTEA and sTEA), the posterior condylar axis (PCA), the anteroposterior axis (APA - Whiteside axis). METHODS Measuring the angles created by the four axes cTEA, sTEA, PCA and APA in magnetic resonance imaging (MRI); determining the femoral rotation angle and application TKR. RESULTS the angle between APA and cTEA 90.41° ± 3.35°, the angle between APA and sTEA 94.47° ± 3.31°, the angle between APA and PCA 96.40° ± 4.59°, the angle between cTEA and sTEA 4.00° ± 1.02°, the angle between cTEA and PCA 6.53° ± 2.55°, the angle between sTEA and PCA 3.48° ± 1.91°. CONCLUSION The angle between sTEA and PCA is the angle that best represents the femoral rotation angle. However, in case of sTEA or PCA is difficult to identify, it can be measure via the APA or cTEA. These angles don't differ by age, gender and place of knee joint.

Its anatomical structure is complex. A proper understanding of PCL anatomy may assist surgeon in reconstructing anatomically native PCL. AIM To describe the anatomical numerical measurement of the PCL in Vietnamese adults. METHODS Twenty-one fresh cadaveric knees were examined. The macroscopic details of the intra-articular PCL, the attachment of the anterolateral bundle (ALB), posteromedial bundles (PMB) to the femur and tibia were analysed. We used a digital camera to photograph the cadaveric specimens and used the ImageJ software to analyse the collected images. RESULTS The ALB and PMB length were 35.5 ± 2.78 and 32.6 ± 2.28 mm, respectively. The smallest and the biggest diameter of middle third of the PCL were 5.9 ± 0.71
