Implication

Systematic review and meta-analysis reveals improved component accuracy and functional scores in knee arthroplasty patients, indicating robotic-arm assistance provides superior surgical precision.

Key Points

To compare component positioning accuracy, alignment and balancing techniques, functional outcomes, complications, and surgeon learning curves between robotic-arm assisted and manual total knee arthroplasty.
Conducted a PRISMA-compliant systematic search across PubMed, Medline, and Google Scholar through October 2020.
Identified and reviewed 16 clinical studies evaluating learning curve (n=5), positioning accuracy (n=6), alignment/balancing (n=7), functional outcomes (n=7), or complications (n=5).
Robotic-assisted surgery achieved significantly lower discrepancies between planned and implanted component positions for coronal femur (mean 1.31, 95% CI 1.08–1.55, p<0.00001) and coronal tibia (mean 1.56, 95% CI 1.32–1.81, p<0.00001).
Patients treated with robotic assistance achieved significantly better short-to-mid-term Knee Society Scores compared with manual arthroplasty (95% CI [-1.23, -0.51], p=0.004).
Surgeon proficiency for operating time was reached within 7 to 11 cases by CUSUM analysis, with no significant differences observed between groups for arthrofibrosis, infection, or overall complication rates.
