[Meta analysis of three-dimensional printing patient-specific instrumentation versus conventional instrumentation in total knee arthroplasty].
Objective: To evaluate the effects of three-dimensional printing patient-specific instrumentation(PSI) versus conventional instrumentation(CI) in the total knee arthroplasty. Methods: According to "patient-specific" , "patient-matched" , "custom" , "Instrumentation" , "Guide Instrumentation" , "cutting blocks" , "total knee arthroplasty" , "total knee replacement" , "TKA" and "TKR" , the litera...
متن کاملComparison of Clinical, Functional, and Radiological Outcomes of Total Knee Arthroplasty Using Conventional and Patient-Specific Instrumentation
Background: Recently, patient-specific instrumentation (PSI) systems have been developed in order to increase theaccuracy of component positioning during total knee arthroplasty (TKA); however, the findings of previous studies arecontroversial in this regard. In the current randomized clinical study, the outcomes of computer tomography (CT)-basedPS (patient specific)-guided TK...
متن کاملAccuracy of patient-specific instrumentation compared with conventional instrumentation in total knee arthroplasty.
Patient-specific instrumentation (PSI) has recently been introduced to improve the alignment following total knee arthroplasty (TKA). However, controversy remains between PSI and conventional instrumentation. The aim of this study is to compare the accuracy of PSI with conventional instruments for total knee arthroplasty (TKA). A systematic literature search was performed in databases including...
متن کاملRotational alignment of femoral component with different methods in total knee arthroplasty: a randomized, controlled trial
BACKGROUND Femoral component rotation (FCR) is one of the most important factors in total knee arthroplasty. In this prospective study, we used three different techniques for FCR and analyzed their accuracy with postoperative axial computed tomography (CT) images. We also evaluated effect of FCR to clinical outcome. METHODS One hundred sixty-five patients were randomly allocated into three gr...
متن کاملAccuracy of Patient Specific Cutting Blocks in Total Knee Arthroplasty
BACKGROUND Long-term survival of total knee arthroplasty (TKA) is mainly determined by optimal positioning of the components and prosthesis alignment. Implant positioning can be optimized by computer assisted surgery (CAS). Patient specific cutting blocks (PSCB) seem to have the potential to improve component alignment compared to the conventional technique and to be comparable to CAS. METHOD...
