Patients with Pain 60 to 120 Days after Total Knee Arthroplasty More Likely to be Dissatisfied at Mid-Term Follow-Up

The purpose of this study was to determine if TKA patients with pain between 60 and 120 days are more likely to be dissatisfied at mid-term follow-up. At the 60–120 day follow-up, moderate to severe movement-elicited pain (MEP) and pain at rest (PAR) were reported by 25/316 TKAs (7.9%) and 44/316 TKAs (13.9%), respectively. A greater proportion of those with MEP at 60–120 days were dissatisfied at midterm follow-up (24% vs. 6.5%, P = .01), and those with MEP early after surgery were 4.5 times more likely to be dissatisfied at mid-term follow-up (P = .004). Similarly, those with PAR 60–120 days after surgery were 4.1 times more likely to be dissatisfied at mid-term follow-up (P = .002).
