What are the stages of posterior tibial tendon dysfunction?

Christopher Chiodo, MD
Orthopedic Surgery
The four stages of posterior tibial tendon dysfunction include:

Stage I: Inflammation and degeneration occurs in the posterior tibial tendon, but the tendon remains strong and there is no change to the arch of the foot.

Stage II: The tendon loses strength as a result of degeneration; the arch becomes partially flattened, but there is no rigid deformity.

Stage III: The posterior tibial tendon is torn and can no longer hold the arch, which collapses entirely. The deformity becomes rigid and there may be arthritic changes in the hindfoot.

Stage IV: The ankle joint becomes arthritic.
