Why the study?
Type D personality compromises joint arthroplasty outcomes, but its influence on total knee arthroplasty outcomes and the temporal stability of its components remained uninvestigated.

Does negative affect and Type D personality predict dysfunctional outcomes in patients undergoing total knee arthroplasty?
Postoperative increase in negative affect is linked to dysfunctional outcomes of total knee arthroplasty, likely due to interaction with pain catastrophizing.
