Research Opportunities

     The Department of Orthopaedic Surgery Faculty and Residents are involved in many new and on-going research projects.  Residents are encouraged to become involved in current projects within the department as well as create their own projects as desired. The University of Illinois provides tremendous opportunities and resources for resident and faculty research.  Residents have access to the University of Illinois Biological Resources Laboratory, the Hektoen Animal Facility, the University of Illinois Biomechanics Lab, and the University of Illinois Orthopedic Laboratory.  At a minimum, each resident is required to complete one research project during his or her five-year residency program.  Below is a sampling of faculty members’ recent publications

Biomechanics Lab

The Orthopaedic Biomechanics Research Lab at University of Illinois at Chicago is directed by Farid Amirouche, PhD. The Laboratory conducts basic and applied research aimed at applying the principles of mechanics and materials science to understand and treat orthopaedic problems. Research projects of varying scope are undertaken in the Laboratory to address problems in musculoskeletal disorders such as osteoarthritis, spine deformity and various fusion techniques, fracture, and pain. Along with our orthopaedic faculty members we design courses and seminars to train residents, and fellows in the principles of scientific investigation.

 

Our research in joint mechanics seeks to combine laboratory experiments, motion analysis studies, and computer simulations. Our current research projects are centered on shoulder, hip and knee with our primary focus being on clinically-oriented research problems across the diverse spectrum of musculoskeletal biomechanics such as joint restoration and joint mechanics including TKA/THA, Cartilage regeneration-Knee repair, Patella instability, Knee balancing with soft tissue kinematics/kinetics, Spine/back pain with spine deformities, Shoulder injuryrotator cuff repair, Upper extremity biomechanics, computer navigation and sports medicine. Currently, our core work is on understanding total and reverse shoulder arthroplasty, rotator cuff repair, selection of artificial grafts and to study the resultant effects these procedures have on the kinematics and kinetics of the shoulder.

 

The Orthopaedic Biomechanics Research Lab is equipped with state-of-the-art equipment to examine the mechanical strength of musculoskeletal systems and implants, investigate the failure mechanism of bone-implant constructs, and study patients’ motion characteristics. The lab is also furnished with a powerful computer and sophisticated software for computer simulation and analysis of complex bone-implant constructs. Our computer generates patient-specific 3D geometric models based on CT/MRI images, performs virtual orthopedic surgery based on the patient's computer model, analyzes the construct strength and evaluates the potential for longterm implant survival. We make use of the finite element method to model and examine the mechanics of soft and hard tissues such as a knee/hip joint. We have developed techniques to build subject-specific finite element models directly from medical image data such as CT, and MRI images. Our techniques also digitize and characterize the material of bone and soft tissues to provide an assessment used in measuring clinical outcomes. Most of our work deals with experimental validation using cadaveric specimens and identification of clinical advantages using sensory and imaging feedback.

 

Our Goal is a commitment to excellence in Orthopaedic Research and our team has been
working diligently with the latest technologies to ensure that our patients have access to the most
advanced treatment options. 

Microsurgery Lab

Information Coming Soon!

Clinical Research Lab

      James Kerns, PhD supervises the portion of the Orthopaedic research laboratory pertaining to neuromuscular-skeletal experiments using rat models with a focus on the nerves, particularly their injury and recovery. This is in conjunction with the interests of the Chairman (Dr. Mark Gonzalez), a dedicated research fellow, mechanical engineers (Dr. Farid Amirouche), residents interested in hand surgery and medical students furthering their research skills. Most studies involve microsurgical, histological and behavioral methods.
