【摘要】：目的据膝关节MRI结合半月板周缘性脱位移位指数统计半月板周缘性脱位的发生率及相关影响因素,探讨其临床意义。方法回顾性分析2015年10月至2016年3月共201例因膝关节疾病在我科住院患者的膝关节MRI。以膝关节股骨和胫骨关节面内外侧缘连线或胫骨平台前缘为基线,半月板滑膜缘突出部分宽度超过同层面自体宽度的25%认定存在半月板周缘性脱位。结果分析发现男女之间(χ2=10.745,P=0.001),内外侧半月板之间(χ2=79.90,P0.001),不同年龄组患者(50岁,≥50岁)之间半月板周缘性脱位的发生率比较差异具有统计学意义(χ2=24.616,P0.001),身体质量指数(body mass index,BMI)不同(25kg/m2,≥25kg/m2)的两组患者之间半月板周缘性脱位的发生率比较差异无统计学意义(χ2=0.248,P=0.619),半月板体部周缘性脱位的发生率与前角和前角+体部的发生率相比差异具有统计学意义(χ2=46.391,P0.001)。经卡方分割法比较,半月板体部脱位的发生率较高。经Logistic回归分析,女性(比值比2.605,95%可信区间1.412~4.807)和年龄(比值比1.051,95%可信区间1.022~1.081)可能是半月板周缘性脱位的危险因素。结论女性和年龄偏大可能是半月板周缘性脱位的危险因素,BMI与半月板周缘性脱位的发生无相关性,内侧半月板较外侧半月板周缘性脱位的发生率高,半月板体部较前角和前角+体部的发生率高。
[Abstract]:Objective to analyze the incidence and related factors of peripheral dislocation of meniscus according to MRI and displacement index of meniscus. Methods from October 2015 to March 2016, a total of 201 cases of knee joint MRIs in our department were analyzed retrospectively. The internal and external lateral line of the femoral and tibial articular surface or the front edge of the tibial plateau were used as the baseline. 25% of the meniscus synovial margin protrusions whose width exceeded the autologous width of the meniscus were found to have peripheral dislocation of meniscus. Results the results showed that there were 50 years old meniscus between male and female (蠂 2 + 10.745) and between lateral and lateral meniscus (蠂 ~ 2 / 79.90 / P ~ (0.001), 蠂 ~ 2 / 79.90 / P ~ (0.001)). There was significant difference in the incidence of perimeniscal dislocation between the two groups (蠂 ~ 2 ~ 2 ~ (24. 616) P ~ (0.001), body mass index (BMI) = 25 kg / m ~ (2), 鈮，
