Mid-term outcomes of distal tibial oblique osteotomy in patients with rheumatoid arthritis: A report of three cases.

Although distal tibial oblique osteotomy (DTOO) has usually been indicated for noninflammatory diseases such as osteoarthritis, we encountered three patients with rheumatoid arthritis (RA) who underwent DTOO. We evaluated radiographic parameters and clinical scores, including self-reported scores for the foot and ankle [self-administered foot evaluation questionnaire (SAFE-Q)] and the Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot scale. In all three cases, radiographic improvements were achieved along with improvements in SAFE-Q and JSSF scores after mid-term follow-up. Supramalleolar osteotomy including DTOO could be indicated even for inflammatory diseases such as RA if erosive changes are not evident in the ankle joint.
