Abstract Background There is no gold standard for the operative treatment of patients with Müller-Weiss disease (MWD). This study reports the mid-term follow-up results for at least 5 years following talonavicular-cuneiform (TNC) arthrodesis for Müller-Weiss disease. Methods A total of 15 patients undergoing TNC arthrodesis for MWD were retrospectively reviewed between January 2015 and August 2017. Two senior doctors assessed the radiographic results twice at each visit (preoperative, three months after the operation, and final follow-up). The clinical results and complications from preoperative and final follow-up were recorded. Results The mean follow up period was 74.0 (range 64 to 90) months. The calcaneal pitch angle, lateral Meary's angle, anteroposterior (AP) Meary's angle, AP talocalcaneal angle, and talonavicular coverage were significantly different before and three months after the operation (p 0.05). The radiological measurements of the two senior doctors were calculated and found to be moderate to strong (ICC:0.899–0.995). The AOFAS, VAS, and SF-12 scores significantly improved at the last follow-up compared to those before the operation (p
