Although long-term functional outcomes are well documented, the incidence and relevance of degenerative changes in adjacent joints of the medial column after first metatarsophalangeal joint (MTP1) fusion remain uncertain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This exploratory single-center follow-up study included patients who underwent isolated MTP1 arthrodesis between 2012 and 2018. Preoperative and final follow-up weight-bearing radiographs were assessed for osteoarthritis progression in the interphalangeal (IP), tarsometatarsal (TMT1), naviculocuneiform (NC), and talonavicular (TN) joints using the Kellgren-Lawrence classification. Radiographic alignment parameters (hallux valgus angle, intermetatarsal angle, hallux-ground angle, and dorsal extension angle) were recorded. Clinical outcome was evaluated using American Orthopaedic Foot &amp; Ankle Society hallux metatarsophalangeal-interphalangeal score (AOFAS HMI) score, Foot and Ankle Outcome Score (FAOS), Foot Function Index (FFI), and a study-specific questionnaire. Paired statistical tests and Pearson correlation analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Seventy-seven patients (45 female, 32 male) were available for follow-up at a mean of 106.9\u2009\u00b1\u200925.3\u2009months. Radiographic osteoarthritis progression was significant in all assessed adjacent joints (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009&lt;\u2009.001) and was most pronounced in the IP joint (66 of 77 joints; 34 of 77 joints progressed by \u22652 grades). TMT1 progression occurred in 23 of 77 joints (\u22652 grades in 5 of 77 joints), and NC or TN progression in 30 of 77 joints (\u22652 grades: NC 6 of 77, TN 8 of 77). Radiographic alignment was not associated with adjacent-joint osteoarthritis progression, metatarsalgia, or patient-reported outcome. Overall, 90.9% reported good or excellent satisfaction. The mean AOFAS HMI score was 79.9\u2009\u00b1\u20099.1, FAOS 86.4\u2009\u00b1\u200915.2, and FFI 18.5%\u2009\u00b1\u20099.3%. Wound healing complications were more frequent with dorsal plating than screw fixation.
