Analysis of related factors of anterior cruciate ligament rupture with meniscus and the effect of arthroscopic surgery / 中国基层医药

ABSTRACT

Objective:To explore the related factors of anterior cruciate ligament rupture with meniscus injury and the effect of arthroscopic surgery.Methods:From July 2014 to May 2018, 98 patients with anterior cruciate ligament rupture admitted to Shengjing Hospital Affiliated to China Medical University were divided into meniscus injury group(67 cases) and without meniscus injury group(31 cases) according to whether they had meniscus injury.The patients with anterior cruciate ligament rupture and meniscal injury were divided into study group(37 cases underwent arthroscopic reconstruction of anterior cruciate ligament and meniscus injury), and 30 cases in control group(only meniscus was repaired under arthroscopy). The factors affecting the anterior cruciate ligament rupture associated with meniscus were analyzed, and the surgical outcomes of the study group and the control group(the cure rate of meniscus injury and the 1-year reoperation rate, IKDC and Lysholm knee function score) were compared.Results:Multivariate logistic regression analysis showed that early course of disease[95% CI(1.444, 41.68), P<0.05], middle course of disease[95% CI(1.682, 52.147), P<0.05], chronic phase[95% CI(3.623, 180.32), P<0.05]), history of recurrent injury[95% CI(2.649, 27.222), P<0.05]) were risk factors of meniscus injury caused by rupture of anterior cruciate ligament.The treatment rate of meniscus injury in the study group[89.19%(33/37)]was higher than that in the control group[66.67%(20/30)], the reoperation rate in the study group[5.41%(2/37)]was lower than that in the control group[26.67%(8/30)], the differences were statistically significant (χ 2=5.084, 5.898, all P<0.05). At 12 months after operation, the scores of IKDC and Lysholm in the study group were (90.25±14.67)points and (88.36±11.25)points, respectively, which were significantly higher than those in the control group[(73.52±10.12)points and (71.47±10.68)points]( t=12.129, 19.309, all P<0.05). Conclusion:The patients with anterior cruciate ligament rupture complicated with meniscus are associated with history and recurrent injury history.Arthroscopic surgery for simultaneous reconstruction of anterior cruciate ligament and meniscus injury can significantly improve knee joint function, improve the cure rate of meniscus injury in this type of patients, and reduce short-term reoperation rate.
