STUDY ON ANA-TOMICAL-MECHANICAL ANGLE AND POSTERIOR CONDYLAR ANGLE ON COMPUTED TOMOGRAPHY IN VIETNAMESE ADULTS
Main Article Content
Abstract
Introduction: Tilt angle and external rotation angle of the femoral condyle are two extremely important parameters, directly affecting the results of knee replacement surgery. These angles vary between species and individuals. The objective of the study is to investigate the parameters of tilt angle and external rotation angle of the femoral condyle on computed tomography in Vietnamese adults. Materials and methods: 120 people (half of each gender) aged 19 to 25 years old participating in the survey had been underwent computed tomography (CT) scan of the entire lower limb. The tilt angle and external rotation angle of the femoral condyle were measured. Results: Ana- tomical–mechanical angle of femur is 5.0± 0.51 (3.2 – 6.1) for men and 4.98± 0.36 (4.0- 6.0) for women, 5.0± 0.4 (3.2-6.1) for both genders. Posterior condylar angle is 3.09±0.29 (2.6-4.0) for men, 3.23±0.34 (2.7-4.5) for women and 3.2±0.3 (2.6-4.5) for both gender. Conclusion: the anatomical–mechanical angle of femur and posterior condylar angle measured on CT images were helpful for total knee arthroplasty
