Abstract:Objective To investigate the correlation between clinical positive signs and meniscus injury of knee joint.Methods The clinical data of 120 patients with meniscus injury of knee joint who were admitted in the Second People′s Hospital of Jingdezhen from April 2016 to March 2020 were retrospectively analyzed.All the patients underwent clinical examination,magnetic resonance imaging (MRI) and arthroscopy.The accuracy and sensitivity of each test in different parts of meniscus tear were compared.Results Among 120 patients,23 cases of anterior horn meniscus tear,51 cases of body meniscus tear,and 46 cases of posterior horn meniscus tear were detected by arthroscopy.The results of arthroscopy were used as the gold standard,the joint space tenderness and grinding tests were more sensitive to meniscus tear at the anterior horn and body than that at posterior horn;McMurray′s test was more sensitive to meniscus tear at the body and posterior horn than that at anterior horn;squatting down test was more sensitive to meniscus tear at posterior horn than that at anterior horn and body,and the differences were statistically significant (P<0.05).There was no statistically significant difference in the specificity of each test in anterior horn body,and posterior horn meniscus tear (P>0.05).Conclusion Clinical positive signs are closely related to the meniscus injury of knee joint,and clinical examination can be used to assist in judging meniscus tear.
