Yes — and more often than people expect. A significant percentage of knee pain originates in the foot, not the knee. Overpronation (the foot rolling inward) torques the knee with every step. Flat feet shift the knee out of alignment. Leg length discrepancies stress one knee more than the other.
A podiatrist can address all of these through biomechanical intervention — without touching the knee at all.
How Foot Problems Cause Knee Pain
The foot is the foundation of the kinetic chain. When it's misaligned, every structure above it compensates. Specifically:
- Overpronation causes internal tibial rotation, which places abnormal stress on the medial knee compartment — a common cause of runner's knee (patellofemoral syndrome) and IT band syndrome.
- Flat feet shift the knee into valgus (knock-knee) alignment, increasing stress on the medial knee and patella.
- High arches / supination reduce shock absorption, transmitting more impact force to the knee with each step.
- Leg length discrepancy — even 5mm — causes the longer-leg hip to drop, straining that knee's lateral structures over thousands of steps.
What a Podiatrist Can Do for Knee Pain
Gait analysis
Most podiatry offices can video your gait on a treadmill and identify the specific movement patterns causing your knee stress. This is the starting point for targeted intervention — without knowing whether you over or underpronated, any treatment is guesswork.
Custom orthotics
The primary intervention for biomechanical knee pain. A custom orthotic corrects foot alignment which in turn corrects knee alignment throughout the gait cycle. Research shows custom orthotics significantly reduce patellofemoral pain syndrome (runner's knee) and IT band syndrome when the root cause is overpronation.
Heel lifts for leg length discrepancy
A simple heel lift in the shoe of the shorter leg can eliminate the compensatory movement that stresses the knee. Inexpensive, immediately effective, and often overlooked.
Footwear prescription
Recommending or prescribing footwear with appropriate stability features for your gait pattern — a motion control shoe for an overpronator, a neutral cushioned shoe for a supinator.
When to See a Podiatrist vs. an Orthopedic Surgeon for Knee Pain
See a podiatrist first if your knee pain:
- Worsens with running or prolonged walking
- Is accompanied by flat feet, overpronation, or foot pain
- Is bilateral (both knees)
- Started after a change in footwear or activity level
See an orthopedic surgeon directly if your knee pain:
- Followed a specific traumatic injury
- Involves significant swelling, instability, or locking
- Is severe and acute
Runner's knee (patellofemoral syndrome) is one of the most common running injuries and one of the most successfully treated by podiatrists. If you're a runner with knee pain that worsens on hills or stairs, see a podiatrist before an orthopedic surgeon — the fix is often biomechanical, not structural.
