Static imaging has been commonly and clinically accepted to assess the severity of medial knee osteoarthritis (KOA), especially the radiography. Gait analysis has been adopted to evaluate the kinematic characteristics of the knees in patients with KOA. Most of the current studies focus on the sagittal plane of the knee, but very few of them focus on the frontal or horizontal plane. With the different severity of medial KOA, anatomical structures of the knees will change and influence kinematics of the knees, such as osteophytes and deformity. At present, there has been no study focusing on the relations between the imaging assessment of the severity and quantitative kinematics of medial KOA. The aim of the study is to explore the relationship between the imaging assessment based on the Kellgren-Lawrence Scores and in vivo 3D knee kinematic characteristics in Chinese patients with medial KOA during walking using a new portal gait system.
All patients are assessed according to the Kellgren-Lawrence Score.

Kinematic characteristics are obtained by the portal gait analysis system in the patients. Kellgren-Lawrence Scores are obtained according to their radiography.
Kinematic characteristics are obtained by the portal gait analysis system in the subjects.Physical examinations are taken to avoid other diseases.
