【摘要】：目的探討膝關(guān)節(jié)內(nèi)側(cè)半月板半脫位對診斷后根部撕裂的價值。方法回顧性分析經(jīng)關(guān)節(jié)鏡證實的120例內(nèi)側(cè)半月板撕裂患者的MRI圖像,將其中60例后根部撕裂患者作為后根部撕裂組,其他撕裂的60例作為對照組,于MRI圖像上測量半月板突出長度,將半月板突出長度≥3mm定義為半月板半脫位,比較兩組半月板半脫位的發(fā)生率。結(jié)果后根部撕裂組中,合并半月板半脫位者56例(56/60,93.33%),對照組中合并半月板半脫位者13例(13/60,21.67%),差異有統(tǒng)計學(xué)意義(χ2=60.15,P0.01)。內(nèi)側(cè)半月板半脫位提示后根部撕裂的敏感度、特異度及陽性似然比分別為81.16%(56/69)、92.16%(47/51)及10.35。結(jié)論膝關(guān)節(jié)內(nèi)側(cè)半月板半脫位可用以提示后根部撕裂。
[Abstract]:Objective to evaluate the value of medial meniscus subluxation in the diagnosis of posterior root tear. Methods the MRI images of 120 patients with medial meniscus tear confirmed by arthroscopy were retrospectively analyzed. 60 patients with posterior root tear were used as posterior root tear group and 60 patients with other tears as control group. The protruding length of meniscus was measured on MRI images. The meniscus protruding length 鈮，
