Persistent subacute pain soon after TKA linked with dissatisfaction at midterm follow-up
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. Researchers found a significantly greater proportion of patients were dissatisfied at their most recent follow-up if they had movement-elicited pain 60 days to 120 days after surgery, with patients who experienced movement-elicited pain early after surgery being 4.5-times more likely to be dissatisfied at midterm follow-up. Similarly, results showed a significantly greater proportion of patients who experienced pain at rest 60 days to 120 days after surgery were dissatisfied at their most recent follow-up. Researchers noted patients who experienced pain at rest early after surgery were 4.1-times more likely to be dissatisfied at midterm follow-up. – by Casey Tingle
