Pes planus is the same as flat foot.

Relationship between flat feet and knee symptoms
The feet always need to be assessed during an evaluation of the knee. With flat feet (pes planus or foot pronation), the lower leg is forced into internal rotation, and the stress is relayed to the knee and the kneecap. Correction with an orthotic can help alleviate symptoms.
Orthotics and pes planus
A visit to an orthotist should determine whether a corrective shoe insert is likely to help with any secondary knee symptoms.
