Background and objectivesTo evaluate feasibility and acceptability of exercise and patient education for patients with hip dysplasia ineligible for surgery.DesignFeasibility study. MethodsFeasibility covered inclusion, retention, and mechanisms of changes (MC). MC were measured with Hip and Groin Outcome Score (HAGOS), hip strength, Y-balance test, and hop for distance test (HDT) over a six-month period. Acceptability covered adherence, expectations, perceptions, benefits and harms. Inclusion and retention were additionally evaluated in six patients following usual care over three months as part of a pilot phase.ResultsThirty of 32 were included (median age: 30 years); six were lost to follow-up. Twenty-four patients improved mean 11 (95%CI: 5-17) HAGOS pain points, improvements in all subscales were 1-11 points. Mean hip abduction strength improved 0.2 (95%CI: 0.04-0.4) Nm/kg, similar to flexion and extension. Median Y-balance test improvements: anterior: 70 (IQR: 64-74) to 75 (IQR: 72-80) centimeters; posteromedial: 104 (IQR: 94-112) to 119 (IQR: 112-122) centimeters and posterolateral: 98 (IQR: 89-109) to 116 (IQR: 108-121) centimeters (p
