Abstract:

BACKGROUND: MRI characterized as non-invasion, high resolution, high sensitivity and specificity to injury has become another important means for diagnosis of knee joint disease following the arthroscopy.

OBJECTIVE: To explore the effective evaluation on the knee meniscus injury diagnosis, by comparing the results of MRI and arthroscopy of the knee meniscus.
METHODS: Clinical data of 206 patients with meniscus injury were retrospectively analyzed. Every case was subjected to MRI and the arthroscopy. The findings of arthroscopy were considered as the golden standard. Then, the sensitivity, specificity and coincidence rate of MRI in the diagnosis of meniscus injury were calculated. The chi-square analysis was used to evaluate the MRI and arthroscopy in the diagnosis of meniscus injury. The Kappa values were used to test the consistency of MRI with arthroscopy in the diagnosis of meniscus injury.
RESULTS AND CONCLUSION: For levels 0 and I meniscus injury, the coincidence rate of MRI was 97%; for level II meniscus injury, the coincidence rate of MRI was 91.1%, and there was no significant difference (P > 0.05). For level III meniscus injury, the sensitivity, specificity, concordance rate and Youden index of MRI were 92.9%, 94.4%, 93.7% and 87.3%, respectively. By the consistency checking, the value of Kappa was 0.874 and χ2 was 38.182, so there was a high consistency checking between the data of MRI and arthroscopy (P=0.000). MRI is a noninvasive diagnostic method for meniscus injury. For patients with levels I and II meniscus injury on MRI, arthroscopy should be cautiously adopted; however, for patients with level III meniscus injury on MRI, arthroscopy should be done as early as possible. Arthroscopic observation is more intuitive that enables to make accurate judgments of meniscus injury to reduce the rate of misdiagnosis.
