Moreover, the percentage of patients who reported no or mild depression increased from 62% to 91%, and those who reported minimal or mild anxiety also increased from 76% to 95%. A multivariate linear regression showed that age, osteoporosis, and smoking were independently associated with the anxiety and depression score changes. These represent not only pain improvement but also a dual benefit in the field of mental health following TKA.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Primary TKA showed significant improvement in patients' depression and anxiety, along with the improvement of their knee functional scores.
