Abstract：Objective: To observe the effect of arthroscopic reduction and retrograde cross-Kirschner wire fixation on tibial intercondylar spine fracture in children.Methods: A total of 80 children with tibial intercondylar spine fracture were treated in our hospital from October 2016 to October 2019.With the simple random number table method, they were categorized into a control group (40 cases) and an experimental group (40 cases).after arthroscopic reduction, two groups of children were treated with internal fixation.The control group was treated with hollow nail fixation, while the experimental group was treated with cross Kirschner wire fixation.After that, the two groups of children were followed up for 10 months.The operation time, bleeding volume, VAS score of pain and Lysholm score of knee joint function of the two groups before and 10 months after operation were compared.The excellent and good rate of knee joint recovery, complications and X-ray of knee joint were followed up.Results: The VAS, Lysholm score, length of operation, amount of bleeding during operation, and no fracture redisplacement or nonunion were found in both groups before operation, and there was no significant difference between the two groups (P>0.05).Compared with before treatment, the VAS scores of the two groups were significantly reduced 10 months after treatment, and the Lysholm scores were significantly improved (P<0.001).The indicators of the experimental group were more significantly improved than the control group (P<0.001).The excellent and good rate of knee joint recovery in the experimental group was 100.00%, significantly higher than that in the control group, 90.00% higher than that in the follow-up.The complication rate in the experimental group was 2.50%, significantly lower than that in the control group.The incidence of symptoms was 15.00%.The difference was statistically significant (P<0.05).Conclusion: In the treatment of tibial intercondylar spine fracture in children, arthroscopic reduction and internal fixation can significantly improve knee joint function, reduce the occurrence of post-operative fracture redistribution or nonunion.The treatment of retrograde cross-Kirschner wire fixation can obtain better knee joint function, relieve postoperative pain, improve the recovery of knee joint function and reduce recovery.The occurrence of complications during the second period is satisfactory.
