Flexible adult flatfoot: soft tissue procedures

Classically, adult posterior tibial tendon dysfunction (PTTD) was considered primarily a tendon rupture and was treated as such with soft tissue repair alone. The understanding that PTTD involves more than simply an inflammatory condition or tendon rupture but also a muscle imbalance, leading to a flatfoot, osteoarthritis, and peritalar subluxation, led to surgeons advocating osseous procedures as well. The advancements in knowledge of the pathomechanics of the deformity have modified the role that soft tissue repair plays in surgical treatment, but the importance of soft tissue restoration in flatfoot repair should not be overlooked.
