6. 내용요약 : Osteoarthritis (OA) is one of the most prevalent joint diseases. While the initiation and different progression rates of the knee OA has not been well understood, it has been suggested that loading condition during the development of a joint can affect cartilage morphology and abnormal joint loading can cause degenerative changes in the joint.
Cartilage morphology is one of the important biomarkers to evaluate cartilage healthiness. A MR imaging protocol for the cartilage and three-dimensional (3D) graphics techniques
have been adapted to create 3D computer models of articular cartilage.
Gait Analysis has been used to understand the in-vivo joint loading conditions during
walking. The peak knee adduction moment which represents the load ratio between the
medial and lateral compartments in the knee was used to understand cartilage thickness
variations in the medial and lateral compartments in the knee for healthy and osteoarthritic knees. The association between the abnormal kinematics of ACL deficient knees relative
To their contralateral knees and the cartilage morphology changes in the ACL deficient
Knees relative to the contralateral knees was tested to understand the joint kinematic
pathways of osteoarthritis for ACL deficient subjects.
The studies on the joint kinematic and kinetic conditions during walking and knee cartilage morphology suggest that the in vivo loading conditions in the knee plays important roles in maintaining healthy cartilage and also in the development of osteoarthritis.
