Individual Project Update March 1, 2005 Design of a Rotational Stability Measurement Device Katie Dillon Stephanie Bechtold, Kara Wagner Mentor: Thore Zantop, M.D.
Compare single bundle vs. double bundle ACL reconstruction techniques Background Design a measurement device to accurately measure axial rotation of the knee Compare single bundle vs. double bundle ACL reconstruction techniques
Preliminary Testing
Redesign current leg rest using plexiglass to replace top board New prototype Redesign current leg rest using plexiglass to replace top board More sturdy than wood Minimize metal Double-board design
9 in 8 in 9 in 8 in
Personal Focus Research inclinometers and level devices for use in our design Inclinometer Measures single axis rotation of lower leg with respect to gravity Small enough to attach to leg between knee and boot Digital readout Level device Ensure that the lower leg is horizontal Small enough to mount on boot
Potential leveling device
Potential Inclinometer
Meet with mentor today to discuss new design Order plexiglass Work to be done Meet with mentor today to discuss new design Order plexiglass Submit Solidworks design to machine shop Begin testing after spring break Testing dates depend on whether the wood or plexiglass protocol is used
