Effect Of Antibiotics On Knee Joint Effusion After Anterior Cruciate Ligament Reconstruction

Objective:To observe the relationship between the use of antibiotics during and after arthroscopic anterior cruciate ligament(ACL)reconstruction and postoperative knee joint production,and the relationship between postoperative knee joint effusion and postoperative joint infection,explore the significance of the use of antibiotics for anterior cruciate ligament reconstruction.Materials and MethodsRetrospective analysis of 768 patients undergoing knee arthroscopy anterior cruciate ligament(ACL)reconstruction from January 2011 to December 2017 at Qianfoshan Hospital affiliated to Shandong University,the surgical methods performed by the patients are the same,and the use of antibiotics varies during and after surgery,the patients were divided into four groups of ABCD according to the increasing order of antibiotic use,Group A did not use antibiotics before and after operation;Group B applied antibiotics 30 minutes before operation,but did not apply after operation;Group C applied antibiotics 30 minutes before operation,1 day after postoperative application;Group D applied antibiotics 30 minutes before surgery After the application for 3 consecutive days,it was deactivated.After three months of surgery,the patient reviewed the patient’s information:To understand the swelling of the knee joint within 3 months after surgery in 4 groups of patients;Whether or not the knee joint puncture was treated by postoperative knee joint swelling,and whether the vital signs of the patient after discharge were changed,including fever,redness and swelling of the knee joint;Whether there are follow-up treatments,etc.,compare the incidence of knee joint effusion between the four groups,postoperative knee joint effusion rate,postoperative knee infection rate and Perform statistical analysis.Result1.Postoperative knee joint swelling:The swelling of the four groups of patients was different after surgery,and the swelling of the knee joint gradually decreased with the increase of the amount of antibiotics used,and the regression time of knee joint swelling in four groups of patients also decreased with the increase of antibiotic use.Among the groups with the lowest antibiotic use,the proportion of patients in group A with joint swelling was the highest,and the incidence of swelling of the knee joint and the amount of effusion was 52.8%.The swelling rate of knee joint in group B was lower than that in group A.The joint fluid accumulation rate of knee joint was 35.5%.The swelling rate of knee joint in group C continued to decrease.The cumulative fluid accumulation rate of knee joint was 26.1%.The D group with the highest antibiotic use had the lowest swelling rate,and the knee joint edema was 21.7%due to swelling of the knee joint.The difference between the four groups was statistically significant(P<0.05).2.Postoperative joint puncture:The postoperative joint puncture of the four groups of patients was different after surgery,and the joint puncture gradually decreased with the increase of the amount of antibiotics used.Among the groups with the lowest antibiotic use,the proportion of patients in group A with joint puncture was the highest,and the incidence of swelling of the knee joint and the amount of effusion was 35.8%.The joint puncture in group B was lower than that in group A.The joint fluid accumulation rate of knee joint was 19.4%.The joint puncture in group C continued to decrease.The cumulative fluid accumulation rate of knee joint was 12.1%.The D group with the highest antibiotic use had the lowest joint puncture rate is 8.7%.The difference between the four groups was statistically significant(P<0.05).3.Postoperative knee infection:In group A without antibiotics,3 patients with knee joint infection occurred after operation,and the postoperative infection rate was 5.7%.There Groups B,C,and D for antibiotics before and after surgery and no infected patients were present,the postoperative infection rate was 0%.ConclusionAppropriate application of antibiotics can reduce the incidence of joint effusion after ACL reconstruction,suggesting that postoperative joint effusion may be related to the proliferation of a small number of bacteria,and the way the bacteria invade the knee joint may be the incision at the knee joint..
