Patients who experienced persistent subacute postoperative pain 60 days to 120 days following total knee arthroplasty were more likely to be dissatisfied with their procedure at midterm follow-up than patients without early pain, according to results.
Researchers identified 275 patients who underwent 316 primary cruciate-retaining total knee arthroplasties (TKAs) and had completed the Knee Society Score and patient satisfaction questionnaire between 60 days and 120 days after surgery and again between 2 years and 5 years after surgery. 
Overall, 7.9% of the TKAs had moderate to severe movement-elicited pain and 13.9% had moderate to severe pain at rest 60 days to 120 days after surgery, according to results.
