This single-surgeon retrospective cohort asks whether the 2018 ICM-PJI Infection Severity score predicts recurrence after revision shoulder arthroplasty. It also tests whether organism virulence and single-stage revision affect the recurrence rate. 157 revisions in 144 patients were graded by ICM-PJI class and followed a minimum of 2 years.
When you face a failed shoulder arthroplasty with a positive culture, the 2018 ICM-PJI Infection Severity score does more than classify. It stratifies recurrence risk from about 2% in the unlikely group up to 17% in the definite/probable group. Use the score to set patient expectations and to flag who needs closer surveillance after revision.
The practice-relevant message is that single-stage revision held recurrence near 5% even in high-severity cases. The authors attribute this to meticulous debridement and optimizing implant stability, not to staging alone.
Organism identity matters as much as the score. MRSA recurred at 30.8%, so a high-virulence culture should lower your threshold for aggressive management and infectious disease input. This is Level III single-surgeon data, so the debridement technique may not generalize, and the comorbidity analysis was underpowered.
