Summary

Patient-specific instruments for total knee arthroplasty offer potential benefits but show minimal gains in current evidence. More data is needed to confirm improved alignment, patient outcomes, or logistical advantages.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Patient-specific instruments (PSIs) are used in total knee arthroplasty (TKA) to shift computer navigation from intraoperative to preoperative planning.
  • These systems rely on preoperative MRI or CT scans, with specifications dictated by instrument manufacturers.

Purpose of the Study:

  • To evaluate the marketed advantages and reported outcomes of patient-specific instruments in total knee arthroplasty.
  • To assess the evidence supporting claims of improved accuracy, reduced surgical time, and better clinical outcomes.

Main Methods:

  • Review of published literature on patient-specific instruments for total knee arthroplasty.
  • Analysis of reported data concerning accuracy, surgical logistics, and patient outcomes.

In Vitro Application of a Wireless Sensor in Flexion-Extension Gap Balance of Unicompartmental Knee Arthroplasty

Published on: May 5, 2023

Main Results:

  • Published results suggest minimal improvements in hospital logistics and limited evidence of enhanced alignment or patient outcomes.
  • Marketed advantages like greater coronal alignment accuracy and reduced surgical time are not consistently supported by current data.

Conclusions:

  • Patient-specific instruments in TKA present disadvantages including increased costs and preoperative time, alongside a learning curve for surgeons.
  • Further research and data are necessary to determine if patient-specific instruments offer significant benefits over standard instrumentation and should be recommended.
