Randomization
knee arthroplasty, TKA
Each center competed for enrollment, adopted the block random method, used an interactive web response system to assign patients who agreed to participate in the study to either the conventional technique (CON) group or the robotic‑assisted system (RAS) group in a 1 : 1 ratio, and then introduced the results into the central randomized system. The researchers intervened patients through the results of the randomized allocation (Fig. A consolidated standard of reporting trials flow diagram is shown. In all, 62 patients were treated with robotic-assisted total knee arthroplasty (TKA) and 61 were treated with conventional TKA.
