Case Report
A 78-year-old woman presented to the clinic with right medial foot and ankle pain with an associated new-onset, planovalgus foot after a fall descending stairs. Preinjury imaging demonstrated an intact posterior tibial tendon (PTT) and normal alignment of the foot. Postinjury imaging revealed PTT rupture and classic features of progressive collapsing foot deformity (PCFD)./r/nThis report provides rare chronologic insight that enhances the understanding of tendon-driven PCFD and how PTT rupture can precipitate a rapid progression in deformity. Early recognition of a PTT injury may be essential to mitigating the rapid onset and progression of PCFD.
