Comparing Of Therapeutic Effects Of Arthroscopic Treatment Fracture Of Intercondylar Eminence Of Tibia In Children With Different Internal Fixatoin Materials

Objective:Retrospective analysis the efficacy of Arthroscopic treatment fracture of Intercondylar eminence of tibia in children.To evaluate the difference of surgical methods and provide help for clinical treatment.Methods:Retrospective analysis 34 pediatric cases of tibial intercondylar eminence fracture treated by Arthroscopy assistent reduction between November 2013 to September 2018.15 patients were treated with hollow screw internal fixation(hollow screw group),6 patients were treated with absorbable cartilage nail fixation(cartilage nail group),and 13 patients were treated with Kirchner wire fixation(Kirschner wire group).Long leg plaster or braces were used for fixation for 4-6 weeks after operation.Regular Outpatient follow-up and telephone follow-up were conducted.The efficacy was evaluated according to Lysholm score,the flexion and extension of the knee,and knee stability.Results:The average time of surgical operationwas 83±36min in hollow screw group,118±21min in the cartilage screw group and82±38min in the Kirschner wire group.The blood loss during surgery was2.47±1.06 ml in the hollow screw group,2.67±1.21 ml in the cartilage screw group,and2.54±1.13 ml in the Kirschner wire group.All children’s incisions were primary healing,and bony healing was achieved within 3 months.At the lastest follow-up,the anterior drawer test and Lachman test of the three groups of children were all negative.One child in Kirschner wire group had a knee stiffness,while the others had normal mobility.The Lysholm score of the lastest follow-up was 97.6±3.53 in hollow screw group,98±2.74 incartilage nail group.and 97.9±2.59 in Kirschner wire group.Conclusion:Arthroscopy-assisted fixation with hollow screw,absorbable cartilage screw and Kirschner wire can all achieve good results in the treatment of tibial intercondylar fractures in children.However,different internal fixation methods have their own advantages.We insist that hollow screw fixation for tibial intercondylar eminence fracture in children has the advantages of simple proccedures,definite fixation,small trauma and quick recovery of the function of the knee.It is an ideal method of treatment for the tibial intercondylar eminence fracture in children.
