Abstract:Objective To investigate the effect of arthroscopic tibial posterior cruciate ligament avulsion fracture fixation with loop plate through three posterior medial approaches.Methods From January 2018 to January 2020,23 patients with PCL tibial avulsion fracture were selected,including 16 males and 7 females.The age ranged from 16 to 46 years,with an average of(32.0±0.2)years.The posterior stinum was opened through the posterior internal three approaches under arthroscopy.The fracture block was exposed,cleaned and reduced.The fracture block was fixed by loop plate through Kirschner pinhole.The subjective knee joint function was evaluated by the international knee documentation committee(IKDC) and Lysholm score,and the knee joint stability was objectively evaluated by posterior drawer test(PDT) and KT-2000.Results 18 cases were followed up at the first,third,sixth,and 12th months after surgeries.All patients were able to freely flex up to more than 120° in the 3 months after the operation,and the fractures healed within 3 months.According to the IKDC functional scoring standard,14 cases were excellent,4 cases were good,and the excellent and good rate was 100%.Lysholm scores were 85 to 100 points,with an average of(95.2±0.56)points.14 cases were negative in PDT test,and 4 cases were grade 1.12 months after operation,the affected knee was(3.43±0.91)mm,and the healthy knee was(2.58±0.72)mm in KT-2000.There was no significant difference in the posterior tibia laxity between the affected knee and the healthy knee(P>0.05).Conclusion Arthroscopic treatment of PCL tibial anchor avulsion fractures with loop plate single tunnel fixation through the posterior internal three-way approach is a reliable operation method of less trauma,convenient operationand low risk.
