Basic Science and Applied Research in Orthopaedic Engineering
The role of the Orthopaedic Engineering Research Laboratory is threefold: 1) to perform biomechanical investigations that address surgical questions and have immediate clinical applications, 2) to engage in basic science research with the potential to significantly change the nature of future orthopedic interventions and 3) to engage and train orthopedic residents and fellows in the process of conducting research as part of their ongoing professional development.
Dr. Peindl has over 35 years of mechanical engineering experience working in both industrial and academic settings in the areas of manufacturing, product development, test engineering and research. Most of his efforts aimed at answering surgical questions with near-term clinical applications involve his previous training in experimental mechanics and biomechanics. The majority of these projects involve the evaluation of fracture fixation devices, joint replacement devices, joint reconstruction techniques or soft tissue attachment devices and/or techniques. These studies necessitate the use of a wide array of experimental instrumentation and techniques aimed at measuring stresses, strains, loads and deformations in implants, external fixation devices, surgical instruments and in hard and soft tissues. Studies are conducted using synthetic specimens, cadaveric specimens or animal models and may involve evaluation of initial structural stability or long-term performance of soft tissue-bone-implant constructs. Dr. Peindl’s background includes experience in photostress analysis (application of photoelastic coatings and stress freezing in photoelastic models), strain gage and brittle coatings analyses and joint motion analyses (kinematic and kinetics) using a variety of motion capture systems.
Over the last 10 years, Dr. Peindl’s laboratory has also been involved in basic science research involving the response of osteoblasts to simulated implant surfaces with varying surface topographies and the development of a new type of osmotic gradient bioreactor system for the growth of articular cartilage. These efforts have resulted in two awarded patents in the area of tissue culture and one patent pending with respect to the bioreactor system. Emerging areas of interest include research in computer-assisted and robotic-assisted surgery and utilization of joint motion analysis and dynamic posturography for quantitative evaluation of orthopedic-related disability and surgical outcomes assessment.
