Abstract

Introduction: This study aimed to establish the diagnostic concordance of meniscal lesions observed through magnetic resonance imaging via the Stoller and Isakos classifications versus the findings of knee arthroscopy.


Methods: Diagnostic tests were conducted at the Alcívar Hospital in Guayaquil, Ecuador, from January to August 2024. Records of patients with meniscus pathology who underwent magnetic nuclear resonance imaging of the knee and arthroscopy were included. The Isakos and Stoller classifications were used. The sample was nonprobabilistic. The analysis corresponds to diagnostic tests.


Results: Nineteen patients were included. Between the Isakos classification and the gold standard (Arthroscopy), a Cohen's kappa index of 0.57 was observed, corresponding to a moderate agreement. A Cohen's kappa index of 0.88 was observed for the internal meniscus injuries, corresponding to very good agreement. Regarding the diagnostic sensitivity and specificity, we can conclude that in the studied group, the Isakos classification showed higher values for both the external meniscus, with a sensitivity of 81.3% and specificity of 100%, and for the internal meniscus, with a sensitivity of 100% and specificity of 85.7%.


Conclusions: Compared with arthroscopy, the Isakos classification is more sensitive and specific for diagnosing meniscus injuries than the Stoller classification.
