Accuracy of patient-specific instrumentation in total ankle arthroplasty: A comparative study

New technologies are constantly being developed with the final purpose of improving medical treatments. Based on preoperative computed tomography, patient-specific instrumentation (PSI) for total ankle arthroplasty (TAA) allows the construction of preoperative plans with respect to bone resections, implant positioning and sizing of the implants. PSI has demonstrated variable results for total knee arthroplasty (TKA) in the past decade. Even though some authors [1 –3] have shown improvement of alignment and decreased operative time in TKA with the use of PSI, recent studies [4,5] have failed to confirm these results.
