Key takeaways:
- Patient-reported anxiety and depression were associated with dissatisfaction after total knee arthroplasty.
- Patients younger than 65 years had the highest rates of anxiety or depression.
Despite having improvements in pain and function, patients with self-reported anxiety or depression were more likely to be dissatisfied after total knee arthroplasty vs. patients without anxiety or depression, according to study results.
Researchers used the Swedish Knee Arthroplasty Register to perform an observational study of data from 8,745 patients (mean age, 70 years) who underwent primary TKA for osteoarthritis between 2017 and 2019.
Researchers analyzed the effect of patient-reported anxiety or depression, which was assessed using the EuroQol 5-D 3-level version, on outcomes including KOOS scores and satisfaction.
According to the study, 35% of patients reported anxiety or depression preoperatively, while 17% of patients reported anxiety or depression at 1 year postoperatively. Overall, 11% of patients reported dissatisfaction with surgery.
After analyzing log-linear regression models, researchers found patients with self-reported anxiety or depression had an increased risk for dissatisfaction preoperatively (RR = 1.23) and at 1 year postoperatively (RR = 2.65). Researchers noted patients younger than 65 years had the highest rates of anxiety or depression. However, they found age was not associated with dissatisfaction at 1 year postoperatively.
“Our findings indicate that preoperative and postoperative patient-reported anxiety or depression increase the risk of dissatisfaction after TKA despite improvements in pain or function,” the researchers wrote in the study. “The results of this study provide further support that anxiety or depression are important, potentially treatable factors to consider in reducing the number of dissatisfied patients after TKA,” they concluded.
