LASMAR, Neylor Pace et al. Assessment of the reproducibility of the Outerbridge and SFA classifications for chondral lesions of the knee. Rev. bras. ortop. [online]. 2011, vol.46, n.3, pp. 266-269. ISSN 0102-3616. http://dx.doi.org/10.1590/S0102-36162011000300006.
OBJECTIVE: To assess the reproducibility of the Outerbridge and the French Society of Arthroscopy classifications between different observers, and to establish a comparison between them. METHOD: Thirty videos on randomly selected knee arthroscopy procedures demonstrating chondral lesions were used. These were classified by six observers: two third-year orthopedics residents and four orthopedic surgeons, of whom two were knee surgery specialists. The intraobserver and interobserver reliability was evaluated by means of the kappa index. RESULTS: The result from the complete evaluation on the Outerbridge classification with all the observers gave a kappa index of 0.434411. For the classification proposed by the French Society of Arthroscopy, the kappa index was 0.45166. CONCLUSION: The Outerbridge and French Society of Arthroscopy classifications for chondral lesions are moderately reproducible between observers. Comparing the two classifications, the proposal from the French Society of Arthroscopy was shown to be more reproducible, and the authors suggest that this classification should be used preferentially in clinical practice for evaluations on chondral lesions of the knee.
