Owing to the presence of microbial biofilm on the implant, the eradication of biofilm-associated infections poses a challenge for antibiotic therapies. The study aimed to investigate the efficacy and safety of the novel antibiotic agent TNP-2092 in the context of implant infections. In vivo, the periprosthetic joint infection (PJI) rats treated with antibiotics showed an increase in body weight and decrease in swelling, temperature, and width of knee, versus the control group. Meanwhile, inflammatory markers in synovium and serum were decreased in the TNP-2092 group, consistent with the pathological results. Moreover, TNP-2092 was effective in eliminating bacteria and disruption biofilm formation, and further alleviated the abnormal bone absorption and reactive bone changes around the prosthesis. In conclusion, intra-articular injection of TNP-2092 is effective and safety in treating knee PJI in rat. The study provides a foundation for the future utilization of TNP-2092 in the management of implant-related infections.
