If your knee feels fine on flat ground but starts hurting when running downhill, you’re not imagining it.
This is one of the most common complaints we see from runners in Austin — especially those increasing mileage or running trails.
Why downhill running causes knee pain
Running downhill increases load on the knee — specifically the front of the knee.
This puts more stress on:
- The patellar tendon
- The quad muscle
- The kneecap tracking
At the same time, your body has to absorb more force with each step.
The real problem (it’s not your knee)
In most cases, the knee isn’t the root issue.
It’s usually:
- Weak quads (especially eccentric control)
- Poor hip stability
- Lack of control when decelerating
- Overstriding
This ties directly into a major 2026 trend: load management — your body isn’t handling the stress being placed on it
Why rest doesn’t fix it
Most runners:
- rest
- feel better
- go back to running
- pain returns
Because the underlying mechanics never changed.
What actually fixes it
At FRWD Sports Therapy, treatment focuses on:
- Eccentric quad strengthening
- Hip stability work
- Running form adjustments
- Manual therapy + dry needling
The goal isn’t just pain relief — it’s improving how your body handles downhill load.
When to get it checked
- Pain with stairs or downhill
- Pain lingering after runs
- Pain getting worse over time
