NCT04590313

Brief Summary

A randomised, controlled trial will be performed by allocating 40 years or older patients with symptomatic hallux rigidus to arthrodesis or watchful waiting group in a ratio of 1:1. Our primary outcome will be pain during walking, assessed by the 0-10 Numeric Rating Scale (NRS) at one year after randomisation. Our secondary outcomes will be pain in rest (NRS), physical function (MOXFQ), patient satisfaction in terms of Patient-accepted Symptom State (PASS), health-related quality of life (EQ-5D-5L), activity level (The Foot and Ankle Ability Measure Sports subscale), use of analgesics or orthoses and rate of complications. Our null hypothesis is that there will be no difference between arthrodesis and watchful waiting in treatment of hallux rigidus. Our primary analysis will be done using intention-to-treat principle.

Masking Details
To avoid biased interpretation of the trial data, blinded data interpretation will be used in the reporting of the results of this trial (70). Before accessing the primary outcome data, the writing committee will record a 'Background assumptions' document containing our definition of MID of the outcome measures, and a brief summary of the key statistical analysis used in the evaluation of the outcome data. The document will be signed by the members of the writing committee and published as an appendix to the primary publication.
