Background: Patient specific guides (PSG's) were developed to improve overall component alignment in total knee arthroplasty (TKA). The aim of this study was to undertake a comparative radiographic study of two commonly used PSG and determine whether the radiographic technique used to construct the PSG had a significant effect on overall alignment.
Methods: This prospective cohort study examined the accuracy of limb-based (n=112) versus knee-based (n=105) MR PSG in restoring the mechanical axis in three planes according to post-operative Perth CT scan protocol.
Patient specific guides (PSGs) are postulated to improve the alignment of components in total knee arthroplasty. Three hundred consecutive total knee arthroplasties performed with either conventional (CON) (n = 185) or Visionaire PSG (n = 115) were evaluated with a CT protocol for coronal limb alignment, coronal and sagittal alignment of individual components and femoral component rotation. There was no statistically significant difference between the two groups in any of the above parameters.

The purpose of this study was to compare the post-operative radiographic alignment and operative time in patients who underwent TKA surgery with PSG, conventional instrumentation or computer-assisted navigation surgery using fully cemented components.
Methods: A cohort of 260 patients who underwent TKA surgery using PSG (PSG group, n=115) was compared to patients who underwent TKA using either conventional instrumentation (CON group, n=92) or computer-assisted navigation (CAS group, n=53).
