Application of Raman spectroscopy to assess the articular surface after performing chondroplasty in rabbits

Abstract

This paper presents the results of expanded analysis after the experimental researches with the samples femoral bones of rabbits in distal epiphysis area using the Raman spectroscopy method. It has been found that values of the optical ratios characterized by reduction of Raman bands during transition from the intact cartilage zone to the PFP plasty region on the wave numbers 956 cm-1 (PO3-4 (symmetric stretching phosphate oscillation)), 1069 cm-1 (CO32-(C-O planar stretching vibration)) and relatively constant coefficients on the wavenumbers 852 cm-1 (Proline), 1250 cm-1 (Amid III), 1587 cm-1 (Amid II) 1660 cm-1 (Amid I ), and also on the 1745 cm-1 ((C=O) Lipids).
