Disabling pain after total knee arthroplasty could contribute to patient anxiety or depression, according to researchers from Avon Orthopaedic Centre in Bristol, United Kingdom.
Using the Hospital Anxiety and Depression Scale (HAD) and the Oxford Knee Score, 40 patients self-reported their outcomes at 3 months and 6 months postoperatively, according to the abstract. The level of anxiety and depression before surgery was correlated with knee disability, with the Oxford Knee Score showing a significant change in preoperative and postoperative scores, according to the abstract. Likewise, postoperative improvement in knee disability was correlated with lower anxiety and depression during both follow-up times.
“The difficulty in interpreting preoperative anxiety and depression and the outcome of TKA is establishing whether they are the cause or effect of pain in the knee,” Julia Blackburn, stated in the abstract. “As anxiety and depression improve with knee pain and function, this study suggests that knee pain contributes to the psychological symptoms and that a successful TKA offers an excellent chance of improving both.”
