Aim: To determine whether peri-operative mental health scores are associated with patient satisfaction after total knee arthroplasty (TKA).

Methods: We conducted a retrospective review of 205 primary TKAs to determine whether the Short Form-12 Mental Component Score (SF-12 MCS) is associated with Press Ganey satisfaction. Univariate logistic regression was used to test for an association between MCS and the likelihood of a 5-star rating for each question.

Results: Patients with low preoperative and postoperative MCS were less likely to give a 5-star rating for provider and staff communication, friendliness, and courteousness but had no association with satisfaction with overall care. A change in MCS in patients with a low preoperative MCS was associated with 5-star satisfaction with appointment scheduling.

Conclusion: Patient mental health status is minimally associated with patient satisfaction. Thus, poor preoperative mental health status should not be a relative contraindication to TKA.
