演題 ： Biomechanics of Knee Impact Injury
要旨 ： Despite efforts to prevent it, knee injury continues to be a problem.
Epidemiological studies of musculoskeletal injuries have indicated the
knee as one of the most commonly injured joints in sporting activities.
In addition, impact forces that can cause soft tissue injuries to the knee
such as ligaments failure also inflict micro damage to the cartilage and
the underlying subchondral bone, increasing the risk of post traumatic
osteoarthritis. Important questions are how does the knee joint (muscles
and ligaments) responds to different impact loads? And how mechanical resilient
are the knee's cartilage and subchondral bone to these extreme impact loads?
To answer these fundamental questions, we have developed computational
musculoskeletal models, finite element models and experiments to obtain
quantitative biomechanical information such as muscles forces, ligament
forces, stress and strain on cartilage and bone in the knee joint due to
impact load. Using data from human subjects' motion analysis experiment,
non injurious loadings were scaled into loads that could cause knee injury
using a high speed mechanical test system on cadavers' knee specimens.
The human subjects' and cadavers' knee joints studies provided data to
apply physiological loadings to small scale osteochondral explants, enabling
the study of realistic bone microstructure damages and degenerative changes
in cartilage. The results will help provide a better understanding of the
knee injury threshold and strategies for knee injury prevention.
