Lateral column osteotomy versus subtalar arthroereisis in the correction of Grade IIB adult acquired flatfoot deformity: A clinical and radiological follow-up at 24 months

•Surgical correction and restoration of anatomical relationship are often required in the treatment of symptomatic Grade II adult acquired flatfoot deformity (AAFD) after a failed course of conservative treatment.•Lateral column lengthening as well as subtalar arthroereisis both achieved comparable radiological outcomes at 24 months after surgery.•There is a role for either techniques in the treatment of symptomatic AAFD. Patients need to be counselled appropriately to appreciate the benefits of each technique.
