目的：探究股骨内侧髁骨髓水肿与膝关节滑膜皱襞病变的相关性。方法选取2012年9月—2014年9月在三峡大学第一临床医学院行关节镜手术患者85例（88膝），观察患者术前MRI股骨内侧髁骨髓水肿分级与关节镜术中滑膜皱襞的病变分级，并进行相关性分析。结果88膝术前MRI显示股骨内侧髁骨髓水肿0级15膝，1级28膝，2级26膝，3级19膝；按照滑膜皱襞的病理分级标准分别为0级6膝（包括5膝不存在滑膜皱襞），1级23膝，2级39膝，3级20膝。股骨内侧髁骨髓水肿与病理性滑膜皱襞病变（包括1、2、3级）之间具有相关性（ rs ＝0.707， P＜0.01）。结论股骨内侧髁骨髓水肿与滑膜皱襞病变之间存在明显相关性。%Objective To explore the correlation between bone marrow edema in medial femoral condyle and synovial plica syndrome.Methods We enrolled 85 patients (88 knees) who underwent arthroscopic surgery in the First Clinical Medical College of China Three Gorges University from September 2012 to September 2014.We determined the grading of bone marrow edema in medial femoral condyle by MRI before surgery and recorded the lesion grading of synovial plica syndrome during arthroscopic surgery .The correlation analysis was conducted between bone marrow edema in medial femoral condyle and synovial plica syndrome .Results For the grading of bone marrow edema in medial femoral condyle of 88 knees by MRI before surgery , there were 15 knees with grade 0, 28 knees of grade 1, 26 knees of grade 2 and 19 knees of grade 3.For the pathological classification standard of synovial plica , there were 6 knee of grade 0 ( including 5 knees that had no synovial plica ) , 23 knees of grade 1, 39 knees of grade 2 and 20 knees of grade 3.There was correlation ( rs=0.707, P<0.01) between bone marrow edema in medial femoral condyle and pathological lesion of synovial plica ( including grade 1, grade 2 and grade 3 ). Conclusion There is obvious correlation between bone marrow edema in medial femoral condyle and lesion of synovial plica .
