The purpose of this prospective, non-randomized study was to evaluate two different surgical treatments for symptomatic planovalgus feet: lateral column lengthening osteotomy and subtalar arthroereisis. The goal of the investigators was to compare the outcomes of these two surgeries and determine whether both treatments resulted in clinical improvement. This was accomplished through the use of pre- and post-operative kinematics, pedobarography, radiographic measurements, and validated outcome measures. The investigators were particularly interested in analyzing the kinematic changes to quantify the changes in the foot mobility and alignment during ambulation, as it has not been previously studied to our knowledge. The investigators hypothesis was that both procedures would show significant improvement and be equivalent in their results.
A prospective trial was conducted. The investigators enrolled fifteen patients (mean age 12.8y, 24 feet) with painful, planovalgus feet refractory to conservative treatment. Seven patients (13 feet) were enrolled in the arthroereisis group, and eight patients (11 feet) were enrolled in the calcaneal lengthening group. Though not specifically excluded, none of the enrolled patients had an underlying neuromuscular diagnosis. Kinematic motion analysis was performed on each patient prior to surgery and at one year of follow-up. Pedobarometry studies, radiographs, and validated outcome questionnaires (Oxford Ankle-Foot Questionnaire for Children) were also performed to evaluate the outcomes of both groups.
