Abstract:Objective To investigate the effect of arthroscopic posteromedial double approaches for tibial avulsion fracture of posterior cruciate ligament fixed with double Endobutton plate.Methods From Feb.2016 to Aug.2017,14 cases of fresh tibial avulsion fracture of posterior cruciate ligament were treated by arthroscopic surgery through anterolateral,anterolateral and posteromedial high and low approaches.There were 10 males and 4 females,aged from 23 to 50 years,with an average age of 36.6 years.The clinical outcomes were evaluated by Lysholm score andthe IKDC subjective knee score before and after operation at 6 months.Knee stability was evaluated with KT-2000.Results All 14 cases were followed up for 6 to 24 months,with an average of 12 months.At 3 months after operation,all the fractures met the clinical healing criteria,and no delayed union or nonunion occurred.The Lysholm scoreafter 6 months of follow-up increased from (36.5±4.9) preoperatively to (87.0±5.2)postoperatively(P<0.05).And the IKDC score was improved from preoperative 53.2±6.4 to (82.5±5.8)(P<0.05).The difference was statistically significant.KT-2000 measurementresults revealed that there were no significant differences between the surgical knee and the normal knee:(2.51±0.73)mm versus (2.82±0.68)mm(P>0.05).Conclusion The technique of arthroscopic posteromedial double approaches and fixationwith double Endobutton plateis satisfactoryin the treatment of avulsion of the posterior cruciate ligament of the knee,and has the advantages of less trauma,simple operation and less complications.
