Arthroscopic Treatment for the Avulsion Fracture of Posterior Cruciate Ligament Tibial Insertion Using Double-Channel"8"Binding Technique
Objective To evaluate the surgical efficacy of the double-channel"8"binding technique under arthroscopy for the treatment of avulsion fractures of the posterior cruciate ligament(PCL)tibial insertion.Methods According to the inclusion and exclusion criteria,the clinical data of 9 patients with PCL tibial avulsion fracture who were treated with double-channel"8"binding technique in Wuxue Chinese Traditional Medicine Hospital from June 2021 to June 2023 were collected.X-rays,CT and magnetic resonance imaging(MRI)were used to evaluate fractures,ligament injuries and healing before and after the operation.The range of motion(ROM),Lysholm score,KT-1000 and other clinical parameters before and after the operation,and postoperative complications were examined and recorded.Results Patients were followed up for 12-24 months,with an average of 16 months.All 9 patients successfully completed the surgery,and postoperative imaging data showed that the fracture fragments were well fixed,and the fracture healed 3 months after surgery.Compared with preoperative data,ROM(133.5°±6.3°vs.31°±3.7°),Lysholm score(84.3±5.2 vs.36.8±2.5),KT-1000[(1.6±0.4)mm vs.(9.6±0.4)mm]all showed significant improvements,with statistical significance(P＜0.05).Conclusion The double-channel"8"binding technique under arthroscopy can realize the"minimally invasive"treatment of avulsion fractures of the posterior cruciate ligament insertion.It has the advantages of fast surgical recovery,little bleeding,low risk of vascular and nerve injury,and economic savings.The surgical effect is definite and suitable for promotion and application in primary hospitals.
