Background

Obtaining accurate alignment in total knee arthroplasty (TKA) remains a concern. Patient specific instrumentation (PSI) created using preoperative 3D modelling was developed to offer surgeons a simplified, reliable, efficient and customised TKA procedure.

Methods

In this prospective study, 60 patients who underwent TKA with conventional instrumentation and 71 patients operated on using PSI were followed for 1 year.(Table 1) The primary endpoint was surgical time. Secondary endpoints included the number of instrument trays used, radiographic limb alignment and clinical outcomes.
