Background: Rheumatoid arthritis (RA) can cause significant forefoot disorders. If forefoot deformity and pain are severe, surgical treatment can be considered. The aim of this study was to analyze the long-term outcomes of surgical forefoot correction per Tillmann, which involves resection of the metatarsal heads through a transverse plantar approach for the lesser toes and a dorsomedial approach to the great toe. Methods: This retrospective study used patient-based questionnaires to analyze the revision rate, pain, use of orthoses, walking ability, forefoot function, and patient satisfaction of patients with RA who had undergone a complete forefoot correction of metatarsophalangeal (MTP) I to V. The study only included participants with RA before the era of biological agents and who were at least 20 years postoperatively. A total of 60 patients who had undergone 100 complete forefoot operations according to Tillmann 24.6 ± 3.5 years ago were included in this study. Results: The data collected showed that 35 reoperations were performed on 26 of the patients. Deformity relapses were often documented for the hallux valgus. More than 60% of the patients were able to wear conventional shoes. The distances the participants were able to walk were significantly increased by wearing shoes when compared with walking barefoot (P < .01). Conclusion: While forefoot function remained difficult to assess, the majority of patients were able to use conventional shoes. This long-term follow-up study of patient-reported questionnaires completed more than 20 years after the Tillmann procedure showed that more than 80% of the patients remained satisfied with the outcome. Level of Evidence: Level IV, retrospective cohort study.
