AIMS AND OBJECTIVES: To assess the effectiveness of pre- and post-operative physiotherapy at home for unilateral total knee replacement (TKR). METHODS: In this pragmatic randomized controlled trial set in participants' homes (four primary care trust areas) and physiotherapy outpatients in a South Yorkshire teaching hospital trust, 160 osteoarthritis patients waiting for unilateral TKR were randomly allocated to intervention (home) group (n=80) or control (hospital outpatient) group (n=80). The intervention group had pre- and post-operative home visits for assessment and treatment by a community physiotherapist. Outcome measures were health-related quality of life (HRQoL), measured by the Western Ontario McMaster Osteoarthritis index (WOMAC) and the Short Form 36 health survey (SF-36) pre-operatively and at 12 weeks post-TKR operation; patient satisfaction; and NHS resource use. RESULTS: No significant differences were observed between the two treatment groups in the primary outcome measure, the WOMAC pain score, or any other HRQoL score. The home group had a significantly greater mean number of physiotherapy sessions than the hospital group [mean difference 5.2 sessions, 95% confidence interval (CI)=-6.3 to -4.1; P=0.001]. There was no significant difference in the total NHS costs per patient between groups. However, home physiotherapy for TKR was significantly more expensive (mean difference-pound136.5, 95% CI=- pound160 to-pound113; P=0.001). Patients were equally satisfied with physiotherapy at home or in hospital; however, more of the home group would choose their location for physiotherapy again. CONCLUSIONS: Although home physiotherapy was as effective and as acceptable to patients as hospital outpatient physiotherapy for unilateral TKR, it was more expensive. Additional pre-operative home physiotherapy did not improve patient-perceived health outcomes.
