While osteotomy yields greater correction of calcaneal inclination and hindfoot valgus, subtalar arthroereisis provides superior restoration of the lateral longitudinal arch and forefoot adduction. Despite these radiographic differences, both techniques provide equivalent functional gains. Due to its minimally invasive nature and favorable safety profile, arthroereisis is a viable first-line option, while osteotomy remains essential for correcting severe structural calcaneal pathology.
