Core Tip

Core tip: The higher revision rate in unicondylar knee arthroplasty compared to total knee arthroplasty is a concern. The cementless unicondylar knee prosthesis (UKP) eliminates one of the technical errors related to failure; the cementing technique. The cementless Oxford UKP also shows reduced radiolucent lines at one year follow-up, whereas the cemented UKP shows occurrence of radiolucent lines. The developing hospital has published encouraging results of the cementless Oxford phase III medial UKP. In our independent retrospective cohort study we observed three revisions of cemented UKP. There were five successful reoperations. The cementless UKP seems to perform better, but no significant difference could be found.
