Factors Associated With Higher Utilization of Outpatient Physical Therapy for Patients Who Have Undergone Primary Total Joint Arthroplasty: A Retrospective Cohort Study

Background: Research has identified predictive factors for inpatient complications and short-term recovery following total knee arthroplasty (TKA) and total hip arthroplasty (THA). Predictors that may influence length of care in outpatient physical therapy (PT) have yet to be examined. Doing so may...

Summary:Background: Research has identified predictive factors for inpatient complications and short-term recovery following total knee arthroplasty (TKA) and total hip arthroplasty (THA). Predictors that may influence length of care in outpatient physical therapy (PT) have yet to be examined. Doing so may improve the quality and efficiency of PT care following TKA and THA. Purpose: The aim of this study was to determine factors associated with a higher utilization of outpatient PT visits for patients who have had primary THA or TKA. Methods: A retrospective cohort study was performed using a population of 5147 patients who underwent THA and TKA between January 2017 and October 2022. Demographic and clinical factors were analyzed to determine which factors influenced PT utilization. Results: Our multivariable linear regression model revealed that female sex, need for inpatient PT visits, and TKA as opposed to THA were significantly associated with an increase in outpatient PT visits. Older age, number of telerehabilitation visits, and history of depression were associated with fewer outpatient PT visits while accounting for all other variables. Conclusions: The results of this retrospective analysis may help to identify some potential factors including TKA vs THA, patient age, and a history of depression that can be evaluated prospectively in future studies to determine whether they predict subsequent outpatient PT utilization.
