The Efficacy Of Computer-assisted Navigation And Traditional Unicondylar Knee Arthroplasty:A Meta-analysis

ObjectiveTo compare the effect of computer-assisted navigation and traditional surgery in unicondylar knee arthroplasty.Through comparative analysis,it can provide reference for clinical treatment and scientific research.MethodBy searching domestic and foreign databases,we collect relevant literature published in domestic and foreign journals,and screen out the required documents through specific inclusion and exclusion criteria.To develop the required clinical evaluation indicators: the accuracy of lower limb mechanical axis,coronal femoral prosthesis implantation,sagittal femoral prosthesis implantation,coronal humeral prosthesis implantation,sagittal tibial prosthesis implantation position;The operation time,postoperative knee joint mobility,postoperative knee KSS score,and complications.Meta-analysis of the included data was performed using RevMan5.3software.ResultsThrough screening of the collected literature,a total of 13 articles were included,including 913 patients with single-chamber osteoarthritis,435 in the computer navigation group,and 478 in the traditional surgery group.Meta-analysis results showed that the navigation group was located in the lower extremity mechanical axis,coronal femoral prosthesis implantation,sagittal femoral prosthesis implantation,coronal tibial prosthesis implantation,and sagittal tibial prosthesis implantation.There was an advantage in accuracy,and the difference was statistically significant(P<0.05).There was no significant difference in KSS scores between the two surgicalmethods(P=0.86).In terms of operation time,the navigation group was more traditional than the traditional group.The required operation time was slightly longer,and the difference was statistically significant(P = 0.002).There was no statistically significant difference in postoperative knee mobility(ROM)between the two surgical procedures(P < 0.00001);There was no statistically significant difference in the incidence of postoperative complications(P = 0.86);there was no statistically significant difference in postoperative knee pain(WOMAC-Pain score)between the two surgical procedures(P = 0.72).ConclusionIn terms of the accuracy of mechanical axis,coronal femoral prosthesis,sagittal femoral prosthesis,coronal tibial prosthesis,sagittal tibial prosthesis and sagittal tibial prosthesis,the navigation group had more advantages than the traditional group in two different methods of unicondylar knee replacement,but in terms of operation time,the navigation group needed longer time,prolonged about 11 minutes in the incidence of postoperative complications,sagittal tibial prosthesis and sagittal tibial prosthesis implantation.There was no significant difference in KSS score,knee joint mobility and limb pain between the two methods.
