Clinical efficacy of AI preoperative planning+3D printed guide plate for high tibial osteotomy in the treatment of knee osteoarthritis
摘要
Abstract
Objective To explore the accuracy and clinical outcomes of opening-wedge high tibial osteotomy(OWHTO)assisted by AI preoperative planning and 3D printed patient-specific instrumentation(PSI)in the treatment of varus knee osteoarthritis(KOA).Methods A retrospective study was conducted on 56 patients(56 knees)who underwent OWHTO at Suzhou Municipal Hospital from January 2020 to September 2022.Among them,25 patients(25 knees)received OWHTO assisted by AI preoperative planning and 3D printed PSI(group A),and 31 patients(31 knees)received conventional OWHTO(group B).Times of intraoperative fluoroscopy,operation time and intraoperative blood loss were compared between the two groups.According to preoperative and postoperative imaging data,the weight bearing line ratio(WBLR),difference between postoperative WBLR and preoperative planned WBLR,medial proximal tibial angle(MPTA),and posterior tibial slope angle(PTSA)were measured and compared between the two groups.During postoperative follow-up,the Oxford knee score(OKS),Lysholm score and knee range of motion(ROM)were used to assess knee function,and the incidence of complications was recorded.Results All patients were followed up for(18.25±4.49)months(12-30 months).Times of intraoperative fluoroscopy,operation time and intraoperative blood loss in group A were less than those in group B(P<0.05).At 6 months after surgery,the OKS of group A was better than that of group B(P<0.05),while there was no significant difference in Lysholm score and ROM comparison(P>0.05).At the last follow-up,there was no significant difference in OKS,Lysholm score and ROM between the two groups(P>0.05).There was no significant difference in the time to return to full weight-bearing of the affected limb between the two groups(P>0.05).There was no significant difference in the incidence of complication rate between the two groups(P>0.05).Postoperative WBLR and MPTA significantly improved in both groups(P<0.05),while PTSA remained unchanged compared with the preoperative values(P>0.05).There was no significant difference in postoperative WBLR,MPTA,and PTSA between the two groups(P>0.05).The difference between postoperative WBLR and preoperative planned WBLR in group A was significantly lower than that in group B(P<0.05).Conclusion OWHTO assisted by AI preoperative planning and 3D printed PSI can achieve satisfactory clinical outcomes in the treatment of varus KOA,and the accuracy is higher compared with conventional OWHTO.It can also reduce intraoperative fluoroscopy times,operation time and blood loss,and simplify the surgical process.关键词
