[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 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 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...
متن کاملThe cruciate ligaments in total knee arthroplasty: a kinematic analysis of 2 total knee arthroplasties.
In vivo weight-bearing fluoroscopic kinematic analysis using an interactive model fitting technique with 3-dimensional computer-aided design solid models was done using 16 anterior and posterior (bicruciate)-sparing and 6 posterior cruciate-sparing total knee arthroplasties (TKAs). All patients had a satisfactory clinical result with a minimum of 12 months' follow-up. The femorotibial contact p...
متن کاملPatient-specific instrumentation does not improve radiographic alignment or clinical outcomes after total knee arthroplasty
Background and purpose - Patient-specific instrumentation (PSI) for total knee arthroplasty (TKA) has been introduced to improve alignment and reduce outliers, increase efficiency, and reduce operation time. In order to improve our understanding of the outcomes of patient-specific instrumentation, we conducted a meta-analysis. Patients and methods - We identified randomized and quasi-randomized...
