Abstract：Objective To explore the curative effect of 3D printing individualized osteotomy mold in total knee arthroplasty (TKA). Methods A retrospective study was performed on 16 patients(20 knees)from April 2014 to June 2016. Patients that were treated with TKA using 3D printing individualized osteotomy mold were divided into the experimental group(3D printing TKA group),the other 16 patients(19 knees)that were treated with conventional TKA were randomly divided into the control group( conventional TKA group) . The HSS score,range of motion( ROM) ,lower limb mechanical alignment and incidence of complication 12 days after operation were recorded. Results After 12 days,the postoperative ROM of knee in the 3D printing TKA group was(104. 3° ± 15. 5°)and that in the conventional TKA group was(103. 5° ± 12. 5°),there was no significant difference between the two groups(P>0. 05). HSS scores in 3D printing TKA group and in conventional TKA group were(88. 5 ± 5. 7)and(89. 4 ± 4. 8),respectively,there was no significant difference between the two groups(P>0. 05). Mechanical alignment in the 3D printing TKA group was(2. 9° ± 1. 1°) and that in conventional TKA group was (3. 0° ± 0. 9°),there was no statistical significance(P>0. 05). There was no obvious intraoperative and postoperative com-plication in the two groups. Conclusion There is no obvious difference between TKA with 3D printing individualized oste-otomy mold and conventional TKA in HSS score,mechanical alignment and ROM of knee.
