Our primary objective was to identify predictive factors for patient expectations of second primary joint replacement surgery on the contralateral side.
We extracted demographic and outcomes data for those undergoing a second joint replacement on the contralateral side. Expectations were assessed before both surgeries with four survey questions. Linear regression modeling was used to identify the factors predicting higher expectations of the second surgery.
In our cohort of 112 patients, the mean duration between surgeries was 2.2 years. There was no difference in the mean expectation score between the two surgeries. Adjusted analysis showed that higher expectations of the first surgery and better preoperative function for the second surgery predicted higher expectations for the second surgery (P<0.05).
Patients with low expectations of the first surgery would benefit from further discussions of their expectations between surgeries with the goal of improving outcomes.
