Research on 3D printing technology assisted anterior cruciate ligament reconstruction for the treatment of anterior cruciate ligament rupture
Objective To explore the auxiliary effect of 3D printing technology in anterior cruciate ligament(ACL) reconstruction under arthroscopy for the treatment of ACL rupture.Methods 102 patients with ACL rupture admitted to Mengjin District Traditional Chinese Medicine Hospital in Luoyang City from January 2021 to December 2023 were divided into a 3D printing group(n=51) and a control group(n=51) according to random number table.The control group received routine arthroscopic ACL reconstruction treatment,while the 3D printing group received arthroscopic 3D printing technology assisted ACL reconstruction treatment.The perioperative indicators,knee joint function (international knee documentation committee[IKDC]score,Lysholm score),knee joint range of motion,and complications were compared.Results There was no statistically significant difference(P>0.05) in the length of the femoral tunnel and length of hospital stay between the two groups;Compared with the control group,the 3D printing group had a shorter surgical time,and the difference was statistically significant(P<0.05);The postoperative Lysholm score and IKDC score in both groups were higher than before surgery,while the IKDC score and Lysholm score in the 3D printing group were(96.32±7.26) and(94.25±3.85),respectively,which were higher than those in the control group(82.66±6.54) and(88.20±8.25),and the difference was statistically significant(P<0.05);The postoperative knee joint range of motion in both groups was higher than before surgery,while the 3D printing group had a knee joint range of motion of(119.25±7.66)°,which was higher than the control group(98.66±8.22)°,and the difference was statistically significant(P<0.05);There were no postoperative complications such as graft fracture,graft impact,infection,deep vein thrombosis,etc.in both groups.Conclusion Arthroscopic 3D printing technology assisted ACL reconstruction surgery for ACL rupture can shorten surgical time,improve knee joint mobility and function,shorten hospitalization time,and have high safety.
