New-Onset Depression after Total Knee Arthroplasty: Consideration of the At-Risk Patient
Postoperative new-onset depression (NOD) has gained recent attention as a previously unrecognized complication which may put patients at risk for poor outcomes after elective total hip arthroplasty. We aimed to investigate risk factors for the development of NOD after total knee arthroplasty (TKA) and assess its association with postoperative complications. (Source: The Journal of Arthroplasty)
