According to recently published results, debridement, antibiotics and implant retention was as viable and safe treatment for periprosthetic infection after primary total knee arthroplasty.
Researchers performed a retrospective cohort study of 58 patients with periprosthetic joint infection after primary TKA who were treated with debridement, antibiotics and implant retention. If a patient was infection free after 2 years, investigators considered the debridement, antibiotics and implant retention successful.
Investigators noted the median time to debridement, antibiotics and implant retention was 21 days. Revision was needed in 34 patients within 28 days and in 42 patients within 42 days. There were 10 patients who needed to be revised more than 90 days after primary TKA.
Results showed the overall success rate after PJI treated with debridement, antibiotics and implant retention was 84%. The success rate of patients who were revised within 28 days was 85% and was 88% for patients revised within 42 days. The success rate was 60% in patients revised more than 90 days after surgery. Despite the involved microorganism, the success rate was 90% for patients revised within 90 days of the primary TKA surgery. – by Monica Jaramillo
