MRI features of patients with knee osteoarthritis and relationship with chronic injury of medial collateral ligament
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.
