Better methods to diagnose cartilage injury or degeneration are needed. Purpose/Hypothesis: To detect the interobserver variance of arthroscopic cartilage grading by subjective judgment using the International Cartilage Repair Society (ICRS) score and by objective measurement using near-infrared (NIR) spectroscopy. We hypothesized that objective measurement of cartilage lesions by NIR spectroscopy will yield more valid results than routine grading using the ICRS score. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Fifteen patients undergoing arthroscopic knee operations were evaluated by 4 experienced arthroscopists independently. The cartilage lesions within the medial knee compartment were estimated by each observer using the ICRS grade and by measurements with a special arthroscopic NIR spectroscopy probe. Results: The ICRS grading had a poor interobserver agreement, with a mean Fleiss kappa index of k = 0.173. Only in 10% (6 of 60) of judged cartilage areas did all 4 surgeons grade the cartilage areas with the same result. In 17 areas (28.3%), the surgeons had a variance of 2 or more grades. In the remaining cases, the surgeons varied within 1 grade. The objective NIR spectroscopyobtained measurements of cartilage resulted in a significant correlation within the observers of R = 0.885 6 0.036 (P\\.001). Conclusion: Our results of interobserver evaluation in real-time arthroscopic cartilage grading suggest that this subjective grading is not satisfactory. This study emphasizes the need for objective measurement techniques for arthroscopic cartilage grading. Near-infrared spectroscopy has a good interobserver correlation. Thus, this method could be developed in the future as a precise method of measuring cartilage lesions."],["dc.identifier.doi","10.1177/0363546510376744"],["dc.identifier.fs","577162"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6179"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60305"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","610"],["dc.title","Near-Infrared Spectroscopy for Arthroscopic Evaluation of Cartilage Lesions: Results of a Blinded, Prospective, Interobserver Study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
