  Background: Primary knee osteoarthritis (OA) is a progressive and disabling disorder affecting up to 13% of individuals aged 65 years and older. Anterior cruciate ligament deficiency (ACLD) is known to be a major precursor of early development of degenerative changes in the knee. There is a possibility of becoming a help of the disease process clarification of knee OA appearance of disease by investigating the relativity of knee OA and ACLD. Methods: Fifteen OA, 9 ACLD, and 9 uninvolved knees were enrolled. In vivo knee kinematics was obtained using a 3D-to-2D registration technique utilizing CT-based bone models and lateral fluoroscopy during a leg press activity. Results: The OA knees were in greater external rotation than the uninvolved and ACLD knees, while there were no differences between the uninvolved .. View More»
