Abstract

INTRODUCTION:

Failed total knee replacement with compromised bone and soft-tissues can be challenging. In these situations, arthrodesis remains a treatment option of a limb-saving procedure.

METHODS:

We investigated the outcome of treatment with an intramedullary cemented knee arthrodesis nail implanted in 22 consecutive patients with forlorn situations after failed total knee replacement.

RESULTS:

There were three major complications due to re-infection and two minor complications due to wound-healing disturbances that healed with the implant retained after an average follow-up of 3.4 years. Clinical examination, Short Form-36 and Oxford knee scores revealed low pain levels, safe implant anchorage, and improved stability of the knee, whilst autonomous mobility utilizing walking aids was still possible.

CONCLUSION:

Bridging knee arthrodesis with an intramedullary nail is a valuable salvage procedure with acceptable clinical results. As recurring infection remains the most challenging complication, regular clinical and radiological follow-up examinations are necessary following implant-related knee arthrodesis to allow timely intervention in case of loosening.
