New evidence highlights the potential of two-stage modular intramedullary knee arthrodesis as a limb-salvage strategy when revision arthroplasty no longer feasible.

A recently published retrospective study in The Journal of Bone and Joint Surgery assessed the outcomes of 30 patients with complex periprosthetic joint infection (PJI) after failed total knee arthroplasty. All patients underwent two-stage modular intramedullary knee arthrodesis using KAM-TITAN arthrodesis system by PETER BREHM.

The study reported sustained infection control at follow-up, early mobilisation, improvements in pain and functional outcomes, and stable fixation. No mechanical or implant-related complications were observed during the study period.

Acc. to the authors, two-stage modular intramedullary knee arthroplasty may offer a limb-salvage option for carefully selected patients who are unsuitable for revision arthroplasty, potentially avoiding above-knee amputation.

Key takeaway: The findings support the potential of two-stage modular intramedullary knee arthrodesis in the management of complex PJI and underline its relevance as a limb-salvage strategy in challenging revision cases.
