Purpose To compare CT-guided and MRI-guided patient-specific instrumentation in total
knee arthroplasty (TKA). Methods Forty-four patients underwent primary TKA using either CT …

Purpose To compare the femoral and tibial components rotational alignment in total knee
arthroplasty (TKA) performed either with conventional or with patient-specific …

Improved component alignment in TKA remains a commonly cited benefit of MRI based
patient-specific instrumentation (PSI). We hypothesized that PSI would lead to improved …

Purpose Performing kinematically aligned total knee arthroplasty (TKA) with generic
instruments is less costly than patient-specific instrumentation; however, the alignment and …

Introduction Patient-specific instrumentation (PSI) was introduced in an attempt to reduce
positional outliers of components in total knee arthroplasty (TKA). It was hypothesized that …

Background Patient-specific instrumentation in TKA has the proposed benefits of improving
coronal and sagittal alignment and rotation of the components. In contrast, the literature is …

Abstract Purpose Patient-specific instruments (PSIs) are already in relatively common use,
and their post-operative radiographic results are equal to those for total knee arthroplasty …

Purpose It was our hypothesis that patient-specific instrumentation (PSI) can improve the
accuracy of the rotational alignment in TKA based on the concept of the system and on the …

Introduction Intraoperative kinematic analysis using a navigation system in total knee
arthroplasty (TKA) has been increasing. The purpose of the present study was to assess the …

Purpose Patient-specific instruments (PSI) were initially developed for the alignment of both
total knee-(TKA) and partial knee arthroplasty (PKA). We hypothesize that CT-based PSI for …
