The patients had functional outcomes evaluated via American Orthopaedic Foot &amp; Ankle Society Score (AOFAS), Foot Function Index (FFI), Tegner Activity Level Scale (TAS), and High-Activity Arthroplasty Score (HAAS) questionnaires. Clinical status was compared across prearthritic, arthritic, and postarthrodesis periods, and satisfaction with return to sport\/exercise activity was recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Patients\u2019 tarsal sagittal ROM (mean [95% CI]: 22.7 degrees [21.4-24.0]); time to union (15.7\u2009weeks [11.8-19.6]); time to walk without gait aid (14.4\u2009weeks [11.0-17.7]); time to return to work (17.9\u2009weeks [15.1-20.8]); and time to exercise activity (20.6\u2009weeks [17.9-23.4]) were recorded postarthrodesis.
