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...

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...

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...
