BME 273 Senior Design Project:
Development of Device to Analyze the
Motion of the Knee Joint
Engineers: Kelly Braun
Tera George
Advisor: Dr. John Dawson
Project Definition
• Build device which holds the femur and
allows unrestricted movement of the knee
joint.
• Measure the different positions of
movement between injured and non-injured
dog knees using imaging device.
Physiology Overview of the
Knee
• Six degrees of motion
» three translational planes
» three rotational planes
• Four Main Ligaments and One Tendon
• Bones of the Knee
» Femur
» Patella
» Tibia/Fibula
Anatomy of the Knee
Previous Work
• Performed literary search on previously
existing devices and techniques used to
measure knee injury.
• Dissected a dog’s leg to understand the
relationship between the bones and the
Quadriceps Muscle.
• Displayed working relationship between
knee joint and quadriceps muscle.
Current Work
• Figuring out dimensions of device we will
build from dissection.
• Dissecting the knee joint itself to learn
about the ligaments used in motion on
Tuesday.
Future Plans
• Begin brainstorming about what our device
will look like.
• Find a way to make the irregularly shaped
bones regularly shaped for easier grip, and
take into consideration the fact that not all
dogs are the same size.
• We will need money to order parts for
construction of the device.
Ultimate Goal
• Build the actual device we designed.
• Dissect and use various dog legs in our
device.
• Test the dog’s legs using the imaging
device.
• Analyze the results and determine what the
differences in movement are between
injured and non-injured knees.
