Our aim was to evaluate medium- to long-term results of patients with advanced Freiberg disease managed with extensor digitorum brevis tendon interpositional arthroplasty.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>There were 24 patients (19 females, 5 males) managed with interpositional arthroplasty for advanced Freiberg disease between 2003 and 2015. The mean follow-up was 133.8 (range, 60-198) months. According to Smillie classification, there were 4 grade 3, 13 grade 4, and 7 grade 5 patients. Patients were evaluated preoperatively and at the final follow-up with the American Orthopaedic Foot &amp; Ankle Society (AOFAS) score and metatarsophalangeal joint range of motion and postoperatively with visual analog scale (VAS) and subjective satisfaction evaluation. Joint space was evaluated on x-rays.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Mean AOFAS score increased (53.9 to 80.3, P = .001). Eight patients had excellent, 14 had good, and 2 had fair scores. A significant increase was found in dorsiflexion (38.1\u00b0 [24\u00b0-52\u00b0] vs 55.3\u00b0 [34\u00b0-65\u00b0]; P = .001) and plantarflexion (19.0\u00b0 [10\u00b0-28\u00b0] vs 28.6\u00b0 [19\u00b0-39\u00b0]; P = .001). Narrowing of the joint space was not seen in any patient, but expansion was determined in all patients (0.39 [0.35-0.47] vs 0.44 [0.41-0.47] cm; P = .002). Of the patients, 9 were very satisfied, 12 were satisfied, 2 were moderately satisfied, and 1 was dissatisfied. The mean postoperative VAS pain score was 1.7 \u00b1 0.9 (0-4).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n
