Abstract:BackgroundPatient-specific instruments have recently gained attention for ensuring the accuracy of osteotomy and correct alignment in total knee arthroplasty (TKA). We aimed to report our experience with TKA performed by using CT-based 3D model of cutting guides in our clinic.Material/MethodsA total of 36 patients (mean age, 67.58±8.46 years; 24 females, 12 males) who underwent TKA with 3D patient-specific cutting guides in our clinic were included in the study. Differences between preoperatively planned bone … Show more
“…b After the wedge was removed, the locking guide was fixed on the femur with the remaining K-wires. c After the wedge was closed accurately, the bolt was inserted patient-specific cutting guides to provide intra-operative guidance for better placement of the implant in total knee arthroplasty (TKA) and to increase the accuracy of osteotomy and post-operative alignment [20]. In the present study, 3Dprinted cutting guides and locking guides were used to locate the osteotomy cut plane and to facilitate closing the wedge respectively for MCWDFO.…”
The use of 3D-printed cutting guides and locking guides can increase the precision of the MCWDFO in patients with lateral compartment disease and valgus deformity, making our surgery more efficiency and occupying less fluoroscopic time.

“… 16 3D-PSIs have emerged as an alternative technique to conventional methods due to their ability to mold to patient-specific anatomy and have shown high accuracy and consistency in pathologies. 17 , 18 , 19 Previous systematic reviews have found that 3D-PSIs have accurate coronal plane alignment with decreased operative times and intraoperative fluoroscopy for osteotomies. 12 , 14 This technique has demonstrated good short-term outcomes postoperatively.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
