Comparison of Self‐Reported Knee Injury and Osteoarthritis Outcome Score to Performance Measures in Patients After Total Knee Arthroplasty

Abstract

Patient self-report by using the KOOS did not reflect the magnitude of performance deficits present after surgery, especially 1 month after TKA. Self-report KOOS outcomes closely paralleled pain relief after surgery, whereas performance measures were not correlated with pain. These results emphasize the importance of including performance measures when tracking recovery after TKA as opposed to solely relying on self-reported measures.
