Clinical Study Of Anterior Cruciate Ligament Injury Combined With Segond Fracture

Objective:To explore the difference of knee joint stability before and after arthroscopic anterior cruciate ligament autogenous tendon reconstruction in patients with Segond fracture,and the effect of fracture block treatment on knee joint function and stability,so as to provide reference for the treatment of anterior cruciate ligament injury with Segond fracture.Methods:50 patients with anterior cruciate ligament injury in our hospital from October 2016 to January 2020 were retrospectively collected,including 28 patients with anterior cruciate ligament injury without Segond fracture(group A)and 22 patients with Segond fracture(group B),13 patients were treated with open reduction and internal fixation of Segond fracture block(Group B1),and 9 patients were treated without Segond fracture block(Group B2).The anterior cruciate ligament injury was diagnosed by X-ray,CT and MRI before operation,and was diagnosed again by arthroscopy during operation.Lysholm knee score and IKDC score were used to evaluate the function and stability of knee joint before and after operation.Results:In this study,all cases were followed up for more than one year,with a follow-up period of 12-18 months,with an average of 15 months.The preoperative Lysholm score and IK DC score of the anterior cruciate ligament injury group(group A)were(55.14)±4.57 score,(42.68)± The last follow-up score was 93.04,respectively ± 3.39 score,(89.79)± 3.27)points;The preoperative Lysholm score and IK DC score of Segond fracture group(group B)were(51.09)± 4.93 score,(40.77)± The score of 3.21 and postoperative score were(92.23)respectively ± 3.31)score,(87.41)± 4.01)points.The score of the two groups was significantly higher than that before operation,P < 0.05,the difference was statistically significant;In the comparison between group A and group B,the preoperative score of group A was significantly higher than that of group B,and the difference between group A and group B was also higher than that of group B,P < 0.05,and the difference was statistically significant;But the difference between the two groups was not significant(P > 0.05).In the anterior cruciate ligament injury group(group B),the Lysholm score and IKDC score were not significant in the treatment group(B1 group)and the untreated group(B2 group),but the difference was not significant.Conclusion:Arthroscopic anterior cruciate ligament reconstruction can significantly restore the function decline and joint instability caused by anterior cruciate ligament injury,which is the first choice for the treatment of anterior cruciate ligament injury and its complications.At present,when the ACL injury combined with Segond fracture,the lateral stable structure of the joint is more seriously damaged,and the function and stability of the knee joint decrease more than that of the simple ACL injury,but the function and stability of the knee joint can be restored to the same level after operation.For patients with anterior cruciate ligament combined with Segond fracture,the fixation of fracture block does not affect the postoperative recovery of knee function and stability,but the fixation of fracture block can reduce postoperative pain,stabilize the structure of anterolateral joint capsule,and accelerate the recovery of knee function and stability.
