Abstract

Introduction

Frailty is associated with poorer outcomes after joint replacement. Targeting frailty pre-operatively via protein supplementation and exercise has the potential to improve outcomes after joint replacement. Before conducting a randomised controlled trial (RCT), a feasibility study is necessary to address key uncertainties and explore how to optimise trial design.

Methodology

Joint PREP is a feasibility study for a multicentre, two-arm, parallel group, pragmatic, RCT to evaluate the clinical and cost-effectiveness of prehabilitation for frail patients undergoing total hip or knee replacement. Sixty people who are ≥65 years of age, frail and scheduled to undergo total hip or knee replacement at 2–3 NHS hospitals will be recruited and randomly allocated on a 1:1 ratio to the intervention or usual care group. The intervention group will be given a daily protein supplement and will be asked to follow a home-based, tailored daily exercise programme for 12 weeks before their operation, supported by fortnightly telephone calls from a physiotherapist. Embedded qualitative research with patients will explore their experiences of participating, reasons for non-participation and/or reasons for withdrawal or treatment discontinuation.
