Kinematics and Arthrokinematics in the Chronic ACL-Deficient Knee are Altered Even in the Absence of Instability Symptoms

摘要

PurposeTo analyze the in vivo kinematics and arthrokinematics of chronic ACL-deficient (ACL-D) and unaffected contralateral knees during level walking and downhill running using dynamic biplane radiography. It was hypothesized that ACL-D knees would demonstrate increased anterior translation and internal rotation, and that ACL-deficiency would alter the tibiofemoral contact paths in comparison to the unaffected contralateral side.
