NCT03435679

Brief Summary

This 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.
