Abstract

Background

After more than 4 decades experience of total knee arthroplasty (TKA), there is still a group of patients who are not satisfied with the outcome. In spite of the improvement of many aspects around the procedure, for unexplainable reasons, patient dissatisfaction is still approximately the same. We conducted this study to analyze correlations between preoperative psychological aspects and dissatisfaction after TKA.

Methods

A total of 186 patients were operated with a primary TKA. Patients filled out the Hospital Anxiety and Depression Scale, Visual Analog Pain Scale (0-100), and Knee injury and Osteoarthritis Outcome Score preoperatively and 4 years postoperatively. Four years postoperatively, the patients also scored their satisfaction degree with the outcome of the surgery.

Results

Of 186 patients, 27 (15%) reported that they were dissatisfied or uncertain with the result of their TKA 4 years postoperatively. Sixteen of those 27 patients had reported anxiety/depression preoperatively compared with 11 of 159 (7%) in the satisfied or very satisfied groups. Patients with preoperative anxiety or depression had more than 6 times higher risk to be dissatisfied compared with patients with no anxiety or depression (P < .001). Patients with deep prosthetic infection had 3 times higher risk to be dissatisfied with the operation outcome (P = .03). Dissatisfied patients had 1-day longer hospital stay compared with the satisfied group (P < .001).

Conclusion

Preoperative anxiety and/or depression is an import predictor for dissatisfaction after TKA. Psychological assessment and treatment preoperatively might improve degree of satisfaction.

Patients and Methods

A total of 186 consecutive TKA patients having primary osteoarthritis were included. We excluded patients having bilateral TKA, dementia, or not being able to speak Swedish. The patients in this study were included in another study regarding the effect of continuous intraarticular analgesia on pain and rehabilitation after TKA [19]. Total number of patients included in that original article were 200, and 14 of these patients were lost during the follow-up period (12 deceased, 2 refused to

Results

Patient characteristics and the overall result are shown in Table 1, Table 2, Table 3. A total of 27 of the 186 patients (15%) reported that they were not satisfied (uncertain or dissatisfied) with the result of their TKA 4 years after surgery. A total of 16 of those 27 patients reported anxiety and/or depression according to the HAD score compared with 11 of 159 (7%) in the satisfied group (satisfied and very satisfied) at the 4-year follow-up. As shown in Table 2, we found that the patients

Discussion

We found in this study that preoperative psychological distress had a significant correlation with patient dissatisfaction 4 years after TKA. In fact, psychological distress, defined as anxiety and/or depression, had the strongest statistical correlation with dissatisfaction 4 years after TKA of all variables studied. The presence of radiographic grade 1 or 2 osteoarthritis according to the Kellgren and Lawrence classification did not correlate with dissatisfaction. Longer postoperative
