| ABSTRACT | |||
| The purpose of this investigation was to use a combination of
image processing, force measurements and finite element modeling to calculate
deformation of the knee cartilage during jumping. Professional athletes
performed jumps analyzed using a force plate and high-speed video camera
system. Image processing was performed on each frame of video using a color
recognition algorithm. A simplified mass-spring-damper model was utilized
for determination of global force and moment on the knee. Custom software
for fitting the coupling characteristics was created. Simulated results
were used as input data for the finite element calculation of cartilage
deformation in the athlete's knee. Computer simulation data was compared
with the average experimental ground reaction forces. The results show the
three-dimensional mechanical deformation distribution inside the cartilage
volume. A combination of the image recognition technology, force plate measurements
and the finite element cartilage deformation in the knee may be used in
the future as an effective noninvasive tool for prediction of injury during
jumping. Key words: Simulation, athletes, injury. |
