ME alumna’s 3-D scanning method impacts artificial hip life

Katie Hollar demonstrated her research for KIVI-TV last fall.

Katie Hollar (ME’17) is now a graduate student improving lives by studying and scanning plastic joint liners in a much faster way. In collaboration with her advisors, she created a 3-D optical scanning technique that helps identify possible problem areas in joint implants. Her scanning and mapping are considered more efficient than current methods. While conventional methods take between 90 minutes and four hours scanning takes only 20 minutes using Hollar’s method.

According to data, more than 330,000 hip replacements are performed each year in the U.S. Improvements over the last fifteen years to the design of joint implants have extended the life expectancy of the technology — one of the biggest improvements being the new plastics. Using Katie’s scanning technique to study the plastic can potentially improve the device materials, which can save thousands of people from undergoing additional surgery and preventing bone loss.
