More Technology, but Similar Early Safety: Robotic Versus Conventional Unicompartmental Knee Arthroplasty, a 30-Day Outcome National Database Study.

The R-UKAs were associated with longer operative times (86.1 ± 34.7 versus 78.9 ± 35.5 minutes; P < 0.001), shorter lengths of stay (0.4 ± 0.8 versus 0.6 ± 1.1 days; P < 0.001), and were more often performed outpatient (92.2 versus 80.9%; P < 0.001).

Chronic obstructive pulmonary disease was the sole significant predictor of AAE, observed only in the robotic UKA cohort (odds ratio = 9.442; P = 0.002).
