Patients were matched in two groups with either 5 or 6 weeks of non\u2010weight bearing. Clinical outcomes were evaluated using the Numeric Rating Scale (NRS) during walking, rest, running, and stairclimbing. Additionally, the Foot and Ankle Outcome Score (FAOS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle\u2010hindfoot score were assessed.

The NRS during walking in the 5\u2010week group improved by 3.5 points and 4 points for the 6\u2010week group (<jats:italic>p<\/jats:italic>\u2009=\u20090.58 at 1\u2010year post\u2010operatively). In addition, all other NRS scores, FAOS subscales\u00a0and the AOFAS scores improved (all n.s. at 1 year follow\u2010up).
