Abstract
Objective To investigate the correlation between the severity of primary degenerative changes of the knee joint and the degree of meniscal injury.Methods A retrospective analysis was conducted on 64 patients with knee osteoarthritis(KOA)treated at Zhumadian Hospital of Traditional Chinese Medicine from December 2022 to December 2024.All patients had completed magnetic resonance(MR)examinations.Based on MR findings,the severity of knee joint degenerative changes and the degree of meniscal injury were assessed,and correlation analysis was performed.Results The severity of KOA lesions was grade Ⅰ in 19 cases(29.69%),grade Ⅱ in 20 cases(31.25%),grade Ⅲ in 14 cases(21.88%),and grade Ⅳ in 11 cases(17.19%).The degree of meniscal injury was grade 0 in 4 cases(6.25%),grade Ⅰ in 20 cases(31.25%),grade Ⅱ in 22 cases(34.38%),and grade Ⅲ in 18 cases(28.13%).In patients with KOA grade Ⅰ,the proportions of meniscal injury grade 0 and grade Ⅰ were the highest;in patients with KOA grade Ⅱ and grade Ⅲ,meniscal injury grade Ⅱ accounted for a higher proportion;in patients with KOA grade Ⅳ,meniscal injury grade Ⅲ accounted for a higher proportion(P＜0.05).Patients with meniscal injury grade Ⅲ had higher T2 relaxation times at the medial and lateral tibial plateaus and the medial and lateral femoral condyles than those with other degrees of meniscal injury;patients with grade Ⅱ meniscal injury had higher T2 relaxation times in the above articular cartilage than those with grade 0 and grade Ⅰ;patients with grade Ⅰ meniscal injury had higher T2 relaxation times in the above articular cartilage than those with grade 0(P＜0.05).The severity of KOA lesions was positively correlated with the degree of meniscal injury(r=0.452,P＜0.05).Conclusion Based on MR findings,patients with more severe KOA had a higher proportion of high-grade meniscal injury,and patients with more severe meniscal injury had longer T2 relaxation times of articular cartilage.The severity of knee joint degenerative changes is positively correlated with the degree of meniscal injury.关键词
