Fifty-one participants aged 50 and older with hip osteoarthritis who were scheduled to receive a total hip replacement participated in this study. We randomized participants into an experiment or a control group. The experiment group used an eHealth prehabilitation program called the Hip Instructional Prehabilitation Program for Enhanced Recovery (HIPPER).

Feasibility indicators addressed process, resources, management, and treatment, and the primary clinical outcome measure was the Hospital Anxiety Depression Scale (HADS).</div></div><div><h3>Results</h3><div>Eight out of 14 feasibility indicators were achieved. All management indicators were achieved. Participant consent and data completion strategies need revision, as 38 % (n = 36) refused participation and 33 % (n = 17) had incomplete data. There were no statistically significant differences between groups for the clinical outcomes (anxiety, pain, activities of daily living, and self-efficacy).
