One-stage Versus Two-stage Revision of the Infected Knee Arthroplasty

Short summary

This randomized controlled study investigates functional outcome and safety after one-stage versus two-stage revision of the infected knee arthroplasty.

Half of participants are treated with a one-stage surgical procedure, while the other half is treated with a two-stage procedure.

The investigators hypothesize that the functional outcome and quality of life of the participants is superior after one-stage surgery compared to two-stage surgery.



Rationale

A two-stage approach is the standard surgical procedure in the treatment of the chronically infected knee arthroplasty, but promising results have been reported after a one-stage approach from single-centre studies.

The potential benefits for the patients treated with a one-stage approach are many as they only have to go through surgery and rehabilitation once with shorter total length of hospital stay. However, no randomized controlled trials comparing outcome after the procedures have been performed so far.

The aim of this study is to investigate functional outcome and safety after one-stage versus two-stage revision of the infected knee arthroplasty.



Description of the cohort

Adult patients:

  • Clinical signs of periprosthetic knee infection
  • > 6 weeks from previous knee arthoplasty procedure (primary or total revision procedure)
  • Speak and understand Danish and have given informed consent



Data and biological material

Questionaires (Oxford Knee Score, 2.EQ-5D-5L)

Clinical data (re-revisions, readmissions, mortality, length of hospital stay)
