(A) Comprehensive analysis of the in vitro performances of different PEEK samples in a heat map. Green denotes high activity and white denotes low. (B–D) In vivo antibacterial assessments after 2 weeks of implantation. (B) Establishment of implant-related infection model. (C) Photographs of bacterial colonies in different groups (left) and the media cultured with different implants for 12 h (right). (D) Quantitative analysis of antibacterial efficiency by counting the bacterial colonies in different groups (n = 4 per group). Statistically significant differences were indicated by *p < 0.05 and ^#p < 0.01 compared with the bare PEEK group.
