Research focus

Our specific areas of research interest are bone regeneration, orthopedic implant fixation and the role of bone in osteoarthritis. Currently, our projects are focused on the following:

  • Genetics of bone regeneration
  • Effects of premature birth on postnatal bone growth
  • Early detection and treatment of particle-induced peri-implant osteolysis
  • Cartilage and bone in osteoarthritis

Many of these projects rely on advanced imaging techniques performed here at Rush and in several national laboratories, including micro-computed tomography, backscatter scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR). Other major methods include histology, mechanical testing, biomarkers and proteomics.

Frank Ko, PhD

My current work is to determine the origin of intramembranous bone regeneration and the genetic basis of spontaneous high bone mass phenotype.  I use rodent models and assess their microarchitectural, functional, and biological properties.  Through these studies, I hope to enhance our scientific knowledge to improve osseointegration, fracture healing, and bone biology.

I completed my BS in Bioengineering at Rice University, PhD in Mechanical Engineering at Cornell University, and postdoctoral training in molecular biology at Massachusetts General Hospital and Beth Israel Deaconess Hospital.  I began my postdoctoral training at Rush in 2018.

I am working on an extension of my dissertation project to use biomarkers for early detection of peri-implant osteolysis after primary total joint arthroplasty. I am now concentrating on using proteomics while my previous efforts were geared toward evaluating candidate biomarkers using ELISA.

The major objective of this work is to verify a biomarker panel for early diagnosis of peri-implant osteolysis, which may postpone the need for revision total joint arthroplasty and allow for non-surgical rescue of implant fixation.

I am originally from the southwest suburbs of Chicago and completed undergraduate studies at the University of Illinois at Chicago where I was awarded a Bachelor of Science in biology with minor study of kinesiology and a Bachelor of Art in psychology. I completed my graduate education at Rush University in the spring of 2019.
