Category:Ankle, Basic Sciences/Biologics, Hindfoot, Midfoot/ForefootIntroduction/Purpose:Adult acquired flatfoot deformity (AAFD) associated with posterior tibial tendon (PTT) dysfunction remains a common orthopaedic problem for which a definitive solution has yet to be identified. Controversy has surrounded the diversity of treatment approaches utilized in current practice, which collectively fail to restore physiologic posterior tibial tendon function. In this proof-of-concept study we proposed a novel passive engineering mechanism (PEM) enhanced flexor digitorum longus (FDL) tendon transfer to address this deficiency. The objective of this study was to determine if PEM-enhancement would better restore physiologic PTT function and gait using a biomechanical flatfoot model. We hypothesized that compared to standard treatment, PEM-enhancement would increase applied FDL tendon force and improve pedobarographic and kinematic gait parameters.Methods:An AAFD model consistent with stage II PTT dysfunction was ...
