    • Comparison of Compressive Stress-Relaxation Behavior in Osteoarthritic (ICRS Graded) Human Articular Cartilage 

      Kumar, Rajesh; Pierce, David M.; Isaksen, Vidar; Davies, Catharina de Lange; Drogset, Jon O.; Lilledahl, Magnus B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-31)
      Osteoarthritis (OA) is a common joint disorder found mostly in elderly people. The role of mechanical behavior in the progression of OA is complex and remains unclear. The stress-relaxation behavior of human articular cartilage in clinically defined osteoarthritic stages may have importance in diagnosis and prognosis of OA. In this study, we investigated differences in the biomechanical responses ...

    • Optical investigation of osteoarthritic human cartilage (ICRS grade) by confocal Raman spectroscopy: a pilot study 

      Kumar, Rajesh; Grønhaug, Kirsten Marie; Afseth, Nils Kristian; Isaksen, Vidar; Davies, Catharina de Lange; Drogset, Jon Olav; Lilledahl, Magnus Borstad (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      Biomolecular changes in the cartilage matrix during the early stage of osteoarthritis may be detected by Raman spectroscopy. The objective of this investigation was to determine vibrational spectral differences among different grades (grades I, II, and III) of osteoarthritis in human osteoarthritic cartilage, which was classified according to the International Cartilage Repair Society (ICRS) grading ...
