Does surgeon handedness affect the outcomes after primary total knee arthroplasty? A retrospective cohort study

Key Points

• Surgeon handedness does not significantly affect overall functional outcomes after total knee arthroplasty, indicating consistency in results.
• The tibial component placement was notably more precise on the dominant side, with fewer positioning outliers observed during procedures.
• This observational analysis suggests that surgeon handedness is less critical compared to surgical technique and planning accuracy, which are vital for effective outcomes.
• The study emphasizes the importance of technique over handedness in knee arthroplasty outcomes, highlighting reliable surgical practices.
