Yayac M, Moltz R, Pivec R, et al. - In this study, the differences in costs and functional outcomes were compared in patients receiving formal PT and those who did not follow primary total hip (THA) and knee (TKA) arthroplasty. Researchers evaluated claims data from a single private insurer distinguishing patients who had undergone primary THA or TKA from 2015 to 2017 in our practice. They recorded demographics, comorbidities, number, and cost of PT visits in a 90-day episode of care. They conducted a multivariate analysis to distinguish significant predictors of outcomes. A total of 2,971 patients were included in the study. The data revealed that participation in formal PT accounts for up to 8% of the episode of care following THA and TKA. For most patients, the role of formal PT should take into account the cost-effectiveness of the intervention.
