Impact of prior failed irrigation and debridement on outcomes of subsequent two-stage revision arthroplasty: a systematic review and meta-analysis

Eur Rev Med Pharmacol Sci. 2022 Dec;26(24):9195-9203. doi: 10.26355/eurrev_202212_30672.

ABSTRACT

OBJECTIVE: This study aimed at examining if prior failed debridement, antibiotics, and implant retention (DAIR) for prosthetic joint infection have an impact on the success of subsequent two-stage revision arthroplasty (2SRA).

MATERIALS AND METHODS: Search was conducted on PubMed, Embase, and Google Scholar up to 14th April 2022 for studies comparing 2SRA with and without a history of DAIR.

RESULTS: Six retrospective studies were included. The success of 2SRA was defined as either absence of additional surgical intervention for infection or absence of antibiotic suppression or both. We noted no statistically significant difference in the odds of success between failed DAIR and no DAIR group, albeit with an inclination of reduced success with prior failed DAIR (OR 0.63 95% CI 0.33, 1.19 I2=66% p=0.16). Five studies reported adjusted outcomes. The meta-analysis demonstrated no statistically significant difference in the odds of success between failed DAIR and no DAIR groups (OR 0.57 95% CI 0.26, 1.26 I2=66% p=0.17). During sensitivity analysis, the removal of a single study changed the effect size indicating significantly lower success rates in failed DAIR group.

CONCLUSIONS: Our results indicate that patients undergoing 2SRA after failed DAIR may have a non-significant tendency of lower success rates as compared to patients directly undergoing 2SRA. However, current evidence is scarce and fraught with several limitations and there is a need for further research to delineate the impact of failed DAIR on the success of 2SRA.
