Late infections, usually occurring months or years after the joint replacement surgery, almost always require removal of the implant, placement of an "antibiotic spacer," and IV antibiotics. Patients who undergo this surgery will need at least 6 weeks of IV antibiotics, possibly more, before a new joint replacement can be put back in the joint.
Once an implant is removed for an infection, can a new one be put back in?
Yes, but not until the infection is cleared. Your orthopedic surgeon, in consult with a infectious disease specialist will determine the optimal treatment schedule, and obtain periodic blood work studies to determine when the infection is likely cured. After that time, a revision replacement (replacement of a joint replacement) may be considered.
