Prosthetic Joint Infection

Patients with a longer time to reimplantation after two-stage resection arthroplasty for prosthetic joint infection may experience worse overall outcomes, according to results.

Although prosthetic joint infections caused by Mycobacterium tuberculosis are rare, they may occur in immunocompromised patients or in people from regions where tuberculosis is endemic, researchers reported in a recent study.

SAN DIEGO — A study designed to determine the optimal articulating knee spacer for two-stage exchange in prosthetic joint infection cases showed similar efficacy and range of motion for two types of spacers studied, a presenter said.

Results showed use of antibiotic-loaded calcium sulfate beads during debridement, antibiotics and implant retention did not reduce the incidence of recurrent prosthetic joint infection at 2 years or 90 days postoperatively.

The results of a randomized controlled trial demonstrated that a 6-week course of antibiotics for prosthetic joint infection was not noninferior to a 12-week course and resulted in a higher percentage of patients with unfavorable outcomes.

A 56-year-old male automotive mechanic with a BMI of 41.4 kg/m2 and bilateral total hip arthroplasties performed at another institution presented to the ED with acute right hip pain and inability to ambulate.

Risk of acute kidney injury was greater in patients with preexisting chronic kidney disease than those without after two-stage exchange arthroplasty with a high-dose antibiotic-loaded bone cement spacer, according to results.

Revision hip and knee surgery poses some unique challenges with a variety of treatment alternatives.

Surgical management of shoulder prosthetic joint infection typically involves one- or two-stage revision shoulder arthroplasty.
