Article Synopsis
- Posterior tibial tendon dysfunction (PTTD) may need surgery if nonoperative treatments are ineffective, and this study evaluates two surgical options: medial displacement calcaneal osteotomy (MDCO) and lateral column lengthening (LCL).
- Twenty patients were divided into two groups for surgery, with both groups showing significant improvements in stride length, cadence, walking speed, and foot positioning after the procedures.
- The LCL group had better heel inversion, while the MDCO group showed enhanced first ray plantarflexion and varus alignment, highlighting that both surgical methods can effectively improve gait and radiographic outcomes for PTTD.
The purpose of this study is to provide a quantitative characterization of gait in patients with posterior tibial tendon dysfunction (PTTD), including temporal-spatial and kinematic parameters, and to compare these results to those of a Normal population. Our hypothesis was that segmental foot kinematics were significantly different in multiple segments across multiple planes. A 15 camera motion analysis system and weight-bearing radiographs were employed to evaluate 3D foot and ankle motion in a population of 34 patients with PTTD (30 females, 4 males) and 25 normal subjects (12 females, 13 males).
