Current treatment selection is based on low evidence as no randomised controlled trials (RCTs) are available. Furthermore, low recruitment rates and intervention crossover are common in RCTs comparing sur- gery to exercise. Patient and public involvement (PPI) may improve trial design and implementation of research findings. Thus, a PPI protocol was embedded into the Progressive Resistance Training versus Total Hip Arthroplasty in Patients with End- stage Hip Osteoarthritis (PROHIP) trial. Purpose / Aim of Study: To explore context-relevant key stakeholder input in order to optimise the design and execution of a planned comparative RCT. Materials and Methods: Fourteen patients undergoing THA, two orthopaedic surgeons and two physiotherapists, and four political stakeholders were recruited. Six focus group interviews were conducted according to group status using semi- structured interview guides. Interviews were recorded, transcribed verbatim and thematic analysed. Findings / Results: Three key themes emerged: (1) Patient recovery expectations, (2) The influence of professional authority, and (3) Inconsistent health care provider communication. Theme 1 suggested that patients experienced their hip problem as disabling and considered recovery without THA unlikely. However, after THA, expec- tations for a quick return to activities of daily living were high. Theme 2 highlighted that both surgeons and physiotherapists claimed expert knowledge and clashed regarding explanatory and management frameworks. Therefore, patients may feel pressured into choosing between THA or exercise. Finally, theme 3 indicated that health care providers tended to use a management narrative best suited to their preferred intervention. Therefore, patients risk being medicalised differently. Conclusions: Patients, orthopaedic surgeons and physiotherapists may introduce systematic bias into the PROHIP trial. Methodological considerations to improve trial design may include development of a neutral patient information narrative delivered by an independent health care provider group during enrolment and a prospective cohort study investigating the external validity. 174.
