Sumario: | BACKGROUND: In recent years, musculoskeletal ultrasound has increasingly become the common method for diagnosis for many medical specialties. Therefore, the present study was performed to evaluate the diagnostic value of point-of-care ultrasonography (POCUS) as a primary triage tool in the diagnosis of the acute medial meniscus injury of the knee. MATERIALS AND METHODS: The present cross-sectional study was performed on patients with a suspected medial meniscus injury of the knee in the emergency department (ED). After history taking and primary physical examination, radiographic imaging of the knee was done. If there was no fracture in the knee X-ray, the POCUS examination on the knee was carried out. All the patients were asked to refer to an orthopedic clinic 2 weeks after discharge from ED for the Magnetic Resonance Imaging (MRI) evaluation. Finally, the POCUS findings were compared with the MRI findings in diagnosing medial meniscus injury. RESULTS: Fifty-five patients with a mean age of 35.48 ± 11.58 years were analyzed in the study (69.1% male). In comparison with MRI scan, the sensitivity and specificity of POCUS in the detection of medial meniscus injury were 85.0 [95% confidence interval (CI), 54.0 to 98.9] and 65.7% [95% CI 42.2 to 85.7], respectively. Its positive and negative predictive values were 58.6% [95% CI 33.8 to 81.5] and 88.5% [95% CI 62.1 to 99.3], respectively. (Area under the ROC curve = 0.726, P value = 0.003). CONCLUSION: The present study demonstrated that POCUS can reasonably be applied in comparison with MRI to evaluate medial meniscus injury. POCUS is an effective initial diagnostic modality in patients with suspected medial meniscus injuries.
