Four patients underwent arthrodesis\u20142 a tibiotalocalcaneal (TTC) arthrodesis and 2 a pantalar arthrodesis. AOFAS scores improved from 30.1 to 77.6 (range, 16-82) ( P &lt; .05) in the SMO group. AOFAS scores improved from 24 to 60.5 (range, 16-66) ( P &lt; .05) in the arthrodesis group. Arthritis grade in the SMO patients was unchanged in 4 patients at final follow-up and worsened in 5 patients by only 1 grade.
