Gathen M, et al. - Authors presented a comparison of outcomes in patients with failed infected total knee arthroplasty (TKA) treated with two-stage revision TKA or knee arthrodesis and assessed the clinical and functional results, implant survival and infection recurrence. They presumed that an arthrodesis may result in beneficial effects on patients’ outcome. A distinct therapy with possible fallback strategies in case of failure was required by the treatment of periprosthetic joint infection (PJI). Compared to revision TKA, a knee arthrodesis when performed as a limb salvage procedure demonstrated no significant benefits on the considered outcome factors but was associated with a significantly lower revision rate. After exhausted treatment modalities, consideration of a knee arthrodesis as an option in selected patients was suggested in the findings.
