Background and purpose - It is unclear whether physiotherapy interventions or patient education before total hip replacement (THR) is beneficial for patients postoperatively. Utilizing the Swedish Hip Arthroplasty Register (SHAR), we retrospectively studied the influence of preoperative self-reported exposure to physiotherapy and/or patient education on patient-reported outcomes 1 year after THR. Patients and methods - Data covering all THRs performed in Sweden for osteoarthritis, between the years 2012 and 2015, was obtained from SHAR. There were 30,756 patients with complete data. Multiple linear regression modelling was performed with 1-year postoperative PROMs (hip pain on a visual analogue scale [VAS], with the quality of life measures EQ-5D index and EQ VAS, and surgery satisfaction VAS) as dependent variables. Self-reported physiotherapy and patient education (yes or no) were used as independent variables. Results - Physiotherapy was associated with slightly less pain VAS (-0.7, 95% CI -1.1 to -0.3), better EQ-5D index (0.01, CI 0.00-0.01), EQ VAS (0.8, CI 0.4-1.2), and better satisfaction VAS (-0.7, CI -1.2 to -0.2). Patient education was associated with slightly better EQ-5D index (0.01, CI 0.00-0.01) and EQ VAS (0.7, CI 0.2-1.1). Interpretation - Even though we found statistically significant differences in favor of physiotherapy and patient education, the magnitude of those were too small and inconsistent to conclude a truly positive influence. Further research is needed with more specific and demarcated physiotherapy interventions.
