Correlation of clinical examination, ultrasound sonography, and magnetic resonance imaging findings with arthroscopic findings in relation to acute and chronic lateral meniscus injuries

McMurray's clinical test, which is the most sensitive method of detecting lateral meniscus lesions, gave the same sensitivity rate for both acute and chronic LM injuries: 65 %. USS was observed to be more sensitive and specific for chronic LM injuries (85 and 90 %, respectively) than for acute LM injuries (71 and 87 %). MRI also yielded higher values of sensitivity and specificity for chronic lateral meniscus injuries (75 and 95 %, respectively) than for acute LM injuries (68 and 87 %). Conclusions The accuracy of ultrasound examination is demonstrated by the high reliability of this method in the diagnosis of lateral meniscus lesions of the knee, and the evaluation performed in this study showed that ultrasound is a useful clinical tool for diagnosing knee pathology.
