Table II.

Pooled success rate per treatment strategy for debridement, antibiotics, and implant retention for knee periprosthetic joint infection per category (low/medium/high) of exchange of modular parts for included cohorts.

Component exchange	Studies, n	DAIR for knee PJI	Treatment success, % (95% CI)
Low (0% to 25%)	1	35	17 (4.7 to 30)
Intermediate (26% to 74%)	8	881	61 (47 to 75)
High (75% to 100%)	37	643	65 (60 to 70)
Overall	46	3,559	63 (58 to 69)

CI, confidence interval; DAIR, debridement, antibiotics, and implant retention; PJI, periprosthetic joint infection.
