Program Overview
The Joint Replacement Surgeons of
Indiana (JRSI) Research Foundation is a
not-for-profit organization committed to
fostering
the
advancement
of
orthopaedic patient care through clinical
and engineering research and education.
The
Orthopaedic
Biomedical
Engineering Laboratory is a partnership
between
Institute
JRSI
of
and
Rose-Hulman
Technology
in
which
students gain laboratory experience while
participating in timely research focused on improving implant design and
surgical techniques.
This program update is an overview of the growth of our program and the
achievements of our students during 2012. In the past year JRSI has
facilitated in-depth research experiences to 9 undergraduate engineering
students, sponsored 2 masters degree candidates in thesis research projects,
facilitated 6 summer research internships in the laboratory and 5 additional
internships for students of other universities at our clinical research facility
in Mooresville, Indiana. Through the infusion of high-tech instrumentation
with clinical and industrial collaboration, our students have made numerous
contributions to the orthopaedic community while developing
engineering skillsets.

Contributing to the Global Knowledgebase
The primary aim of the JRSI Foundation is to generate high-quality,
peer-reviewed literature in an effort to contribute to the global orthopaedic
and engineering communities. In the past year, we presented our research
within the following national conferences and medical journals:

A Student Thank You
To the Supporters of the Rose-Hulman-JRSI Research Partnership:
Rose-Hulman provides its students with exceptional opportunities, one of
which is the partnership with the Joint Replacement Surgeons of
Indiana (JRSI). In one summer of research at JRSI’s Rose-Hulman lab, I had
access to more research experience and opportunities than most
undergraduate students could hope for. My experience with JRSI’s
excellent equipment and the facilities available at Rose-Hulman has set me
apart as an applicant for graduate school. In addition to the
excellent equipment and facilities available to students doing research with
JRSI, I was also able to learn how research studies are designed and
implemented.
I was
able
to contribute
to
developing
the
test
methods and perform the testing and data analysis for the study now
published in Clinical Orthopaedics and Related Research. I was also honored to
give an oral presentation of the research at the BMES Annual
Meeting that year. Seeing a study through from test methods to results is a
unique opportunity. Having that study published in a major journal and
presenting the research at a major conference before completing my
Bachelor’s
degree
is
exceptional.
I
would
not
have
had
such
exceptional accomplishments without the opportunities provided to me by
JRSI. Scott Small makes it clear to the students working in the lab that he
wants us to gain valuable, worthwhile research experience. The students are
actively involved in every stage of a study.
This provides the students of Rose-Hulman with the opportunity to gain
valuable and worthwhile research experience that sets us apart in a significant
way.
I
am
now
applying
to
graduate
school
programs
focused on Biomechanics and Orthopedic Engineering. The experience and
accomplishments that JRSI has made possible have given me a priceless
advantage. I am very grateful to Scott Small and JRSI and to Rose-Hulman
for continuing to provide exceptional opportunities that help the students of
Rose-Hulman to excel.
Yours sincerely,
Mary (“Betsy”) Jones
Betsy has a passion for both biomedical engineering and the United Kingdom. She aims to
study in a biomechanics graduate program at either the University of Oxford in Oxford or
Imperial College in London, beginning in the fall of 2013.

Current Investigations
Evaluation of Micromotion in Fixed
and Mobile Bearing Total Knee
Arthroplasty Designs
Summary: Excessive micromotion
in total knee replacement is an
indication of an unstable implant.
This study compares two tibial
component designs to identify
differences in initial stability
following implantation.
Assessment of Dynamic and Static
Balance After Partial and Total Knee Arthroplasty
Summary: Patient balance after joint replacement surgery is crucial to
limiting
risk
of
falls
and
subsequent
injury.
This
study
compares balance before and after surgery in patients with partial and
total knee replacements.
Analysis of Heat Generation and Torque in Deformed Total Hip
Arthroplasty Acetabular Components
Summary: Previous studies have shown that some acetabular
components change shape once implanted into the pelvis. This study
examines the effect of that shape change on friction, torque, and heat
generation at the ball-and-socket joint.
Finite
Element
Modeling
of
the
Tibia
Following
Unicompartmental Knee Arthroplasty
Summary: Computer imaged-based modeling allows for quick and
efficient study of the interactions between bone and implant following
arthroplasty surgery. This study is the development of a validated
computational model of partial knee arthroplasty.
Comparison of Manufactured Composite Tibia Models with Native
Tissue
Summary: Manufactured bone models exist to enable clean and
repeatable biomechanics research. This study is an attempt to compare
the mechanical response to joint replacement surgery of manufactured
tibias versus cadaveric human tissue.
Student Experiences within the
Healthcare Setting
Through
the
JRSI
research
program,
Rose-Hulman engineering students gain
unique exposure to the medical community.
Students in our program each spend a day in
the operating room at the Center for Hip
and Knee Surgery in Mooresville, Indiana
observing
JRSI
orthopaedic
surgeons
performing hip and knee replacement
surgeries. In 2012 our students additionally
worked with a local imaging center collecting
CT imaging data for use building threedimensional computational models of tissue
specimens. JRSI surgeon Michael Berend, MD made multiple lab visits in
2012 to participate in biomechanical testing and to offer hands-on
demonstrations of surgical techniques to our students.
Community Outreach
As a part of the mission of the Rose-Hulman—JRSI relationship, our
program is committed to outreach activities which recruit and train young
students in the fields of engineering and medicine. For the past three years
our

in
the

school students into the laboratory to learn basic engineering principles
while demonstrating research equipment and methods.
