The Efficacy of Three-Dimensional Printed Personalized Osteotomy Guide Technology on the Balance Function of Total Knee Arthroplasty
Objective:To evaluate the proprioception and balance function of total knee arthroplasty between 3D printing personalized osteotomy guide technology and conventional instrumentation.Methods:50 patients with primary unilateral total knee arthroplasty were randomly divided into 3D printing personalized osteotomy guide technology group and conven-tional instrumentation group,25 patients in each group.There was no statistically significant difference in age,gender,body mass index,and degree of deformity between the two groups preoperative.The hip-knee-ankle angle(HKA),coronal femoral component component angle deviation,coronal tibial component component angle deviation,posterior femoral condyle(PCA)and transverse axis of patella to femoral con-dyle line angle(PFA)were compared between the two groups.The knee society scores(KSS)clinical score,KSS functional score,Western Ontario and McMaster Universities(WOMAC)score,and knee joint range of motion were com-pared between the two groups at 3 months after surgery.P-K252 balancing apparatus was used to evaluate the difference in proprioception and stability of patients.Results:There were no serious complications in both groups.The coronal femo-ral prosthesis deviation,PCA and PFA in the 3D printed osteotomy guide group were less than those in conventional instrumentation group(P＜0.05).The KSS functional score of the 3D printed osteotomy guide plate group was better than conventional instrumentation group(P＜0.05).The motion track area and motion track perimeter of the 3D printed osteotomy guide plate group were smaller than conventional instrumentation group(P＜0.05),and the Berg Balance Scale(BBS)score was higher than that of conventional instrumentation group(P＜0.05).There were no significant difference in HKA deviation and coronal plane tibial prosthesis deviation between the two groups(P＜0.05).There were no signifi-cant differences in KSS clinical score,WOMAC score,knee joint range of motion and average swing value and knee motion between the two groups(P＞0.05).Conclusion:The application of 3D printed personalized osteotomy guide plate in total knee replacement can achieve better lower limb stability in this study.
