Accuracy 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 کاملImplant positioning in TKA: comparison between conventional and patient-specific instrumentation.
The number of total knee arthroplasty (TKA) procedures continuously increases, with good to excellent results. In the last few years, new surgical techniques have been developed to improve prosthesis positioning. In this context, patient-specific instrumentation is included. The goal of this study was to compare the perioperative parameters and the spatial positioning of prosthetic components i...
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 کاملComparative study of CT guided patient specific jig assisted TKA and conventional instrumentation TKA
Results: Mean rotational femoral angle was 1.0° for cases group and 1.5° for the control group, difference was statistically significant. The difference in preoperative and postoperative HKA angles between case and control groups was found to be significant in both groups but more in cases group. The alignment of knee in cases was closer to ideal 6-degree valgus alignment than the control group...
متن کاملComparison of planned and achieved implant position in total knee arthroplasty with patient-specific positioning guides
BACKGROUND AND PURPOSE Intraoperatively, patient-specific positioning guides (PSPGs) represent the preoperatively planned alignment. We investigated the degree of correlation between preoperative planning and the alignment achieved postoperatively with the PSPG technique. PATIENTS AND METHODS TKAs performed with the PSPG technique between 2009 and 2011 were included. 39 patients (42 TKAs) vol...
