Tendon Transfer versus Allograft Reconstruction in Progressive Collapsing Foot Deformity

The posterior tibial tendon (PTT) is the principal dynamic stabilizer of the medial longitudinal arch of the foot. The basic goal of surgically reconstructing PCFD is to restore the foot's medial longitudinal arch, often through a combination of bony and soft tissue procedures. While the FDL transfer has long been the gold standard for reconstruction, allograft reconstruction of the PTT has recently been increasing in popularity.
