Comparison 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 for total shoulder arthroplasty
Shoulder arthroplasty is a demanding procedure with a known complication rate. Most complications are associated with the glenoid component, a fact that has stimulated investigation into that specific component of the implant. Avoiding glenoid component malposition is very important and is a key reason for recent developments in pre-operative planning and instrumentation to minimise risk.Patien...
متن کاملAlignment 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 کاملReview article: Patient-specific versus standard instrumentation for total knee arthroplasty.
This meta-analysis reviewed 12 studies comparing patient-specific instrumentation (PSI) with standard instrumentation (SI) for total knee arthroplasty in terms of postoperative coronal alignment and operation time. There is no significant difference between PSI and SI in terms of hip-knee-ankle angle (overall coronal alignment or mechanical axis), tibial coronal alignment, and operation time.
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...
