NCT04247672

Brief Summary

To accomodate dissatisfied patients with a total knee arthroplasty (TKA) and improve outcomes, several knee systems have been developed. The cemented ATTUNE TKA shows superiority over other established knee systems at short-term, abating with longer follow-up. There have been no studies reporting on the results of the uncemented version of the ATTUNE. Therefore, the main objective of the current study was to report patient reported outcome measures (PROMs), survivorship and complications associated with the uncemented ATTUNE TKA.
