Why Knee Pain Often Comes From the Hip and Foot

Knee pain is rarely just a “knee problem.”

The knee sits between the hip and the foot - and often pays the price when either of those regions fails to control load.

Who This Is For

- People with ongoing knee pain in walking, running, or squatting

- Athletes with repeat knee overload issues

- Clinicians interested in kinetic chain mechanics

The Big Picture (Plain Language)

The knee is a hinge that responds to forces from above (hip and pelvis) and below (foot and ankle).

When:

- The hip can’t control femur position

- The foot can’t manage ground forces

The knee absorbs the mismatch.

Pain is often the symptom, not the source.

The Deeper Layer (Anatomy, Physiology, Control)

Key contributors:

- Weak or poorly timed hip abductors/external rotators → femoral internal rotation and adduction

- Collapsing arch or poor foot control → tibial rotation and valgus stress

- Trunk and pelvic control → where the centre of mass travels relative to the knee

This changes load on:

- Patellofemoral joint

- Meniscus

- Ligaments

- Tendons

Over time, tissues report the imbalance as pain.

What This Means in Real Rehab

Strengthening the quads alone rarely solves the whole problem.

Effective rehab must address:

- Hip strength and timing

- Foot stability and proprioception

- Trunk and pelvic control under load

- Movement patterns in tasks like squatting, stepping, running

The knee improves when the system around it behaves better.

What We Actually Do at Biokinetics

We look at:

- How the knee tracks during real tasks

- How the foot interacts with the ground

- How the hip and trunk respond to single-leg loading

Rehab then targets the weakest links while still respecting any local knee pathology.

When to Seek Further Review

Red flags like locking, giving way, or acute traumatic injury may require imaging and medical or surgical input.

Closing Reflection

Knee pain is often the messenger.

The message usually starts at the hip or the foot.

Biokinetics treats knee pain through the full chain - from the ground to the pelvis and beyond.
