Abstract

Purpose: Patient Acceptable Symptom State (PASS) is characterized as the highest level of symptom state beyond which patients consider themselves well and achieve the desired functional status. The Joint Replacement version of the Hip Disability and Osteoarthritis Outcome Score (HOOS-JR) is used to assess the outcomes of total hip replacement (THR) in the USA. This study examined the characteristics of people who do or do not achieve PASS as reflected on HOOS-JR scores 6-months after THR. Methods: Data for people who underwent THR at a tertiary care hospital were extracted from clinical charts. The HOOS-JR scores at pre-surgery and 6-months after THR were extracted from the charts. People with HOOS-JR scores of >76.7 at 6-months after THR were considered responders (achieved PASS), and those ≤76.7 were considered non-responders (did not achieve PASS). A multivariate binary logistic regression assessed the relationships between demographic and health variables, LBP, and pre-surgery HOOS-JR scores as independent variables and responder or non-responder as the dependent variable. The odds ratio (OR) was interpreted as the index of association, where OR with p values of <0.05 were considered significant. Results: Twenty-four patients (37.5%) from the sample failed to achieve PASS at 6-months after THR. Logistic regression analysis identified higher BMI (OR=1.16, 95% confidence interval [CI]=1.01-1.34; P=0.03) and lower pre-surgery HOOS-JR scores (OR=1.06, 95% CI=1.01-1.10; P=0.01) were found to be significantly associated with achieving PASS for HOOS-JR at 6-months after THR. Conclusions: This study's results indicate that people with higher BMI or lower pre-surgery HOOS-JR may not achieve optimal functional status at 6-months after THR. Physical therapists can provide interventions to improve lower extremity function in people scheduled to undergo THR to enable patients to experience timely recovery in hip function after THR.
