Ankle dorsiflexion and plantarflexion ROM were measured, and isokinetic strength was assessed bilaterally at 30\u00b0\/s and 120\u00b0\/s. Clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Score and the Foot and Ankle Outcome Score (FAOS). Radiographic assessments were performed at final follow-up.\r\nResults: At a mean follow-up of 77 months, the mean FAOS was 83.5 \u00b1 15.6. According to the AOFAS classification, 21% of patients were rated as excellent, 43% good, 14% fair, and 21% unsatisfactory. Dorsiflexion ROM was significantly lower on the affected side compared to both the contralateral limb (5.57\u00b0 \u00b1 3.94 vs. 18.36\u00b0 \u00b1 3.08, P = .003) and the control group (22.57\u00b0 \u00b1 4.22, P &lt; .001). While plantarflexion ROM did not significantly differ, isokinetic strength was significantly reduced in most parameters, particularly in dorsiflexion.\r\nConclusion: Patients with surgically treated Myerson type B Lisfranc injuries exhibit persistent deficits in ankle dorsiflexion ROM and in isokinetic strength and endurance of both dorsiflexion and plantarflexion, despite favorable clinical scores and radiographic outcomes. These findings highlight the importance of incorporating objective functional assessments in the long-term follow-up of these patients.\r\n\u00a0\r\nCite this article as: Demirel M, Kara\u00e7am M\u0130, Ayan MO, \u015eahinkaya T, Utlu DK, Polat G.
