Comparative study of open surgery and arthroscopic assisted surgery in management of knee dislocations

Objective To compare the efficacy of open surgery and arthroscopic assisted surgery in treatment of knee dislocations.Methods A retrospective case-control study was conducted to analyze the clinical data of 80 patients with knee dislocations admitted to Second Hospital of Lanzhou University from May 2013 to September 2019,including 59 males and 21 females,aged 18-66 years[(42.5±11.6)years].Open multiple ligament reconstruction was performed in 49 patients(open group)and arthroscopic assisted multiple ligament reconstruction was performed in 31 patients(arthroscopic group).The postoperative hospitalization days,incidence of complications,time needed for recovery of knee range of motion(>0°,>90°,>120°),and time to complete weight-bearing were compared between the two groups.The Lysholm score,international knee documentation committee(IKDC)subjective knee form,Tegner activity level,score of the MOS item short-form health survey(SF-36),patient satisfaction and knee range of motion were compared between the two groups at the last follow-up.Results All the patients were followed up for 1.2-7.4 years[(3.8±1.5)years].There was no significant difference in postoperative hospitalization days or incidence of complications between the two groups(P>0.05).No significant difference was found in time needed for recovery of knee range of motion(>0°,>120°)or time to complete weight-bearing(P>0.05).The time needed for recovery of knee range of motion(>90°)was 90(60,90)days in open group and 60(30,90)days in arthroscopic group(P<0.05).At the last follow-up,there was no significant difference in Lysholm score,IKDC subjective score,Tegner activity level,SF-36 score,or patient satisfaction between the two groups(P>0.05).At the last follow-up,the knee range of motion was 120°(90°,130°)in open group and 135°(120°,140°)in arthroscopic group(P<0.05).Conclusion For treatment of knee dislocations,open surgery and arthroscopic assisted surgery have similar results in the long-term effect,while arthroscopic assisted surgery has benefits in early rehabilitation and ultimately better knee range of motion.
