Patient-Reported Anxiety or Depression Increased the Risk of Dissatisfaction Despite Improvement in Pain or Function Following Total Knee Arthroplasty: A Swedish Register-Based Observational Study of 8,745 Patients

Remaining pain and functional limitations may cause dissatisfaction in patients after total knee arthroplasty (TKA). Furthermore, anxiety and depression are associated with remaining postoperative symptoms and dissatisfaction. We investigated if patient-reported anxiety or depression increased the risk of dissatisfaction 1 year after TKA in patients who improved in pain or function.
