CONFERENCE ACE REPORTS
This ACE Report is a summary of a conference presentation or abstract. The information provided has limited the ability to provide an accurate assessment of the risk of bias or the overall quality. Please interpret the results with caution as trials may be in progress and select results may have been presented.
Why was this study needed now?
Many randomized controlled trials have been performed evaluating the efficacy of patient-specific instrumentation. Despite being developed for improving alignment, results from previous studies have been inconsistent.
What was the principal research question?
In total knee arthroplasty, is there any significant difference in postoperative alignment between patient-specific instrumentation and conventional intramedullary instrumentation?
|Population:||133 patients scheduled for total knee arthroplasty.|
|Intervention:||PSI: Procedures were performed using patient-specific instrumentation. (n=69)|
|Comparison:||CONV: Procedures were performed using conventional intramedullary instrumentation. (n=64)|
|Outcomes:||The main outcome of interest was deviation of the components from recommended alignment on CT. Outliers were considered at deviation >3 degrees in either direction.|
|Time:||Time of CT was not reported in the conference abstract.|
What were the important findings?
What should I remember most?
How will this affect the care of my patients?
