Abstract
A cartilage-tissue analysis device includes: an illuminating fiber that emits, from a light-emission surface thereof, laser light coming from a laser light source; two light-collecting fibers that receives scattered light at respective light-receiving surfaces the distances from which to the light-emission surface differ from each other; and detector that detects Raman spectra from the scattered light received by the light-collecting fibers. The cartilage-tissue analysis device is configure to: calculate an intensity ratio between two Raman bands originating from cartilage tissue and subchondral bone tissue, respectively, from each of the two Raman spectra; and evaluate a state of the cartilage tissue by selecting, from among the two Raman spectra, a Raman spectrum the intensity ratio of which is within a prescribed range and that analyzes the selected Raman spectrum, to analyze the selected Raman spectrum.
