We study early responses to joint injury to learn about the pathogenesis of osteoarthritis and to identify intervention strategies.  We study chondrocyte mechanobiology to understand how mechanical forces are translated into biochemical responses.  We study cartilage matricellular proteins to gain insight into how cells interact with growth factors and the extracellular matrix.
We use animal models of joint injury and bone formation, explant models of osteochondral injuries, stem-cell based tissue engineering, and 3-axis bioreactors to mechanically stimulate hydrogel-embedded chondrocytes and stem cells.
We apply the knowledge to translational studies. Example: Intervene with inflammatory gene expression upon joint injury to prevent or delay OA. Example: Enhance BMP-mediated bone regeneration by presenting the growth factor in a biologically relevant context on matricellular proteins.

Eric O. Klineberg, M.D.

I am very invested in clinical outcomes research, particularly in the setting of spinal deformity.  Much of this work is focused on spinopelvic parameters, sagittal balance and the influence of deformity correction on patient outcomes.  Much of this work is now referenced, and is a guideline for deformity correction around the globe.  More information on the International Spine Study Group (ISSG) may be found online at
My basic science research focus is on stem cells for bone regeneration, the biology of spine fusion, and characterization of disc degeneration. Ultimately the goal is to derive biological and biomechanical solutions to provide an optimal fusion or regeneration platform that will consist of matrix, cells and proteins. Many different collaborators are involved in this research endeavor.
