Prevalence and Predictors of Symptom Resolution and Functional Restoration in the Index Knee After Knee Arthroplasty: A Longitudinal Study

The prevalence of complete pain relief was 34%, the prevalence of complete pain and symptom relief was 14%, and the prevalence of complete functional restoration was 29% after KA. Participants who are older and with lower (better) WOMAC Pain scores were more likely to be pain-free after surgery. These data collected from a community-based sample have the potential to inform clinicians screening patients for KA consultation in a shared decision-making discussion to better align patient expectations with the most likely outcome.
