摘　　要：目的:探讨膝骨关节炎(KOA)患者MRI特征及与内侧副韧带(MCL)慢性损伤的关系。方法:选取2023年1-6月583例KOA患者,分为MCL慢性损伤组和无损伤组,分析MCL慢性损伤的相关因素。结果:MRI发现:内侧半月板脱位44.25%,ACL损伤23.50%,后交叉韧带损伤21.44%,骨赘形成56.43%,关节间隙狭窄普遍,骨髓水肿平均2.02±0.65分。损伤组多项指标及女性、≥60岁占比均高(P<0.05)。Logistic回归分析显示,ACL损伤、内侧半月板脱位、骨赘是MCL慢性损伤的独立风险因素(P<0.05),特定关节间隙狭窄具保护作用(P<0.05)。结论:MRI可观测KOA的内侧半月板、交叉韧带损伤、骨赘及骨髓水肿。ACL损伤、内侧半月板脱位、骨赘是MCL慢性损伤的独立风险因子,关节间隙狭窄具保护性。Objective:To explore the MRI characteristics of knee osteoarthritis(KOA)patients and their relationship with chronic injury of the medial collateral ligament(MCL).Methods:583 KOA patients from January to June 2023 were selected and divided into MCL chronic injury group and non injury group to analyze the related factors of MCL chronic injury.Results:MRI findings:medial meniscus dislocation accounted for 44.25%,ACL injury accounted for 23.50%,posterior cruciate ligament injury accounted for 21.44%,osteophyte formation accounted for 56.43%,joint space narrowing was common,and bone marrow edema averaged 2.02±0.65 points.Multiple indicators in the injury group,as well as the proportion of females and those aged≥60,were all high(P<0.05).Logistic regression analysis showed that ACL injury,medial meniscus dislocation,and osteophyte were independent risk factors for chronic MCL injury(P<0.05),while specific joint space stenosis had a protective effect(P<0.05).Conclusion:MRI can observe the medial meniscus,cruciate ligament injury,osteophyte,and bone marrow edema of KOA.ACL injury,medial meniscus dislocation,and osteophyte are independent risk factors for chronic MCL injury,and joint space stenosis has a protective effect.
