RESUMEN
OBJECTIVES: The Hip Injection Trial (HIT) compared the effectiveness of adding a single ultrasound-guided intra-articular injection of either corticosteroid and local anaesthetic or local anaesthetic alone to advice and education among people with hip osteoarthritis (OA). This nested qualitative study explored participants' experiences of living with hip OA and of the trial treatment they received. METHOD: Semi-structured telephone interviews were undertaken with a purposeful sample of trial participants after a 2-month trial follow-up. Interviewers were blinded to which injection participants had received. Thematic analysis using constant comparison was undertaken prior to knowing the trial results. RESULTS: 34 trial participants were interviewed across all arms. OA causes pain, physical limitations, difficulties at work, lowered mood, and disrupted sleep. Those who received advice and education alone felt that they had not received 'treatment' and described little/no benefit. Participants in both injection groups described marked improvements in pain, physical function, and other aspects of life (e.g., sleep, confidence). The perceived magnitude of benefit appeared greater among those who received the corticosteroid injection; however, the length of benefit varied in both injection groups. There was uncertainty about the longer-term benefits of injection and repeated injections. CONCLUSION: Hip OA is highly burdensome. Participants perceived little/no benefit from advice and education alone but reported marked improvements when combined with either injection. However, the magnitude of benefit was greater among those who received corticosteroid. The varying duration of response to injection and uncertainty regarding longer-term benefits of injection and repeated injections suggests that these areas are important for future research.

BACKGROUND: Weight loss is recommended as a core treatment for individuals with hip osteoarthritis who are overweight or obese. Physiotherapists play an important role in managing patients with hip osteoarthritis, but little is known about how they address weight. We aimed to explore how UK-based physiotherapists currently address weight loss among individuals with hip OA. METHODS: We carried out a mixed-methods study. A cross-sectional questionnaire was mailed to 3,126 UK-based musculoskeletal physiotherapists. Self-reported approaches to addressing weight loss among individuals with hip osteoarthritis were explored using a case vignette and associated clinical management questions. Semi-structured telephone interviews (n = 21) were completed with a purposeful sample of physiotherapists who returned the questionnaire and provided consent for further contact. Interview data were analysed thematically. RESULTS: There was a 53% response rate to the questionnaires (n = 1,646), and 1,148 responders were eligible for analyses (based on having treated an individual with hip OA in the last 6 months). Eight-five per cent of physiotherapists reported that they would address the vignette patient's weight, usually via advice (70%). Interviews identified that advice often focused on the importance of weight loss, with some physiotherapists offering basic advice on how to achieve weight loss. Multiple factors influenced their approach, including confidence, perceived remit and patient receptiveness. CONCLUSIONS: UK physiotherapists commonly address weight loss among patients with hip osteoarthritis, by offering advice relating to the importance of weight loss. However, provision of more specific guidance on how to achieve weight loss is variable. With additional training, physiotherapists could play an important role in supporting weight loss among patients with hip OA, thus potentially optimizing treatment outcomes.
