Alignment and component position after patient-matched instrumentation versus conventional total knee arthroplasty.
PURPOSE To compare patient-matched instrumentation (PMI) with conventional total knee arthroplasty (TKA) in terms of limb alignment and component position. METHODS Nine men and 36 women (mean age, 69.5 years) who underwent PMI TKA were compared with 20 men and 25 women (mean age, 69.3 years) who underwent conventional TKA by the same team of surgeons with the same prosthesis and protocols in ...
متن کامل[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 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...
متن کاملComponent position alignment with patient-specific jigs in total knee arthroplasty.
BACKGROUND The failure to restore mechanical alignment and appropriate rotational axis intraoperatively has been described as one of the most common causes of implant failure in total knee arthroplasty (TKA). Both conventional and computer-assisted TKA have their limitations. Patient-specific jigs (PSJ) offer a possible alternative method for TKA. The aim of this study was to investigate if the...
