Infection Risk for TKA Following Injections and Arthroscopy of the Knee: How Long Should We Wait ?
OrthoEvidence Journal (OE Journal) - OE Original
OE Journal. 2021;9(10):2This article explores the ongoing debate around the optimal timing of total knee arthroplasty (TKA) following prior knee interventions—specifically knee arthroscopy and intra-articular injections. Drawing on recent observational studies, the article highlights significant variability in infection and complication rates depending on how soon TKA is performed after these procedures. While evidence suggests waiting at least 9 months after arthroscopy and 7 months after injections may reduce adverse outcomes, clinical decisions must remain individualized. The article also addresses methodological challenges in current studies and emphasizes the need for higher-quality research to guide timing recommendations.
