Abstract：Objective The purpose of this study was to compare the clinical efficacy of using a bone cutting guide with conventional high tibial osteotomy in the treatment of knee medial osteoarthritis.Methods This study included 103 patients who underwent high tibial osteotomy at our hospital,randomly divided into two groups:the guide-assisted group(51 patients)and the control group(52 patients).The guide-assisted group underwent high tibial osteotomy assisted by a bone cutting guide,while the control group underwent traditional surgery.Surgical time,intraoperative fluoroscopy frequency,medial proximal tibial angle(MPTA),postoperative mechanical axis deviation angle was compared.Knee Society Score(KSS)and Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)were used to evaluate knee joint function and pain before and after surgery.Adverse reaction rates and rehospitalization rates between the two groups were also statistically analyzed.Results The guide-assisted group showed significant advantages over the control group in terms of intraoperative fluoroscopy frequency(3.69±1.4 vs 8.65±1.6),surgical time(63.05±15.25 vs 71.41±13.05),postoperative MPTA(88.2±1.4 vs 87.2±1.9),and postoperative mechanical axis deviation angle(1.1±0.8 vs 1.6±1.2),(t=-16.63,-2.67,2.66,-2.30,P<0.05).Both groups were followed up for 1 year.In terms of WOMAC scores,the experimental group showed better stiffness scores at 1 month(2.2±1.23 vs 2.7±1.36)and 3 months(2.2±1.1 vs 2.7±1.30)postoperatively compared to the control group(t=-2.04,-2.04,P<0.05).In terms of KSS scores,at 3 months postoperatively(73.8±11.5 vs 69.4±7.9)and 6 months postoperatively(77.56±7.9 vs 74.36±7.2),the experimental group was superior to the control group(t=2.32,2.15,P<0.05).There was no significant difference between the two groups in the occurrence rate of adverse events and rehospitalization after surgery.Conclusion Our study results indicate that the use of a bone cutting guide in assisted surgery significantly reduces intraoperative fluoroscopy frequency and surgical time compared to traditional surgery,with smaller deviation angles.This suggests that the use of a bone cutting guide can reduce intraoperative radiation exposure,improve the accuracy of knee joint surgery,and serve as an important adjunctive method for osteotomy correction.
