Runner's knee: it hurts at the front, it gets fixed higher up

A diffuse ache around or behind the kneecap that shows up while running, going down stairs, or after sitting a long time with the knee bent. It’s hard to point at with one finger: it’s more “this whole area”. It’s called patellofemoral pain and it’s the most common complaint among new runners.

What it isn’t

It isn’t wear and tear. You aren’t “using up your cartilage”. That idea frightens people into quitting, and it isn’t what the evidence describes: it’s a problem of how load is distributed across the joint, and that can be changed.

What works, and where

Here the evidence is unusually clear. The international consensus statement on patellofemoral pain recommends exercise therapy, and specifically the combination of hip and knee work. Meta-analyses comparing the two separately point the same way: adding hip work to quadriceps work gives better results for pain and function than quadriceps alone.

The reason makes sense: if the hip doesn’t control the thigh well, the knee drifts inward on every landing and the kneecap works crooked. Strengthening the knee without fixing what’s above leaves the cause where it was.

What to do tomorrow

• The app’s strength session already includes what’s needed: glute bridge, squat and lunge work exactly that.
• You don’t have to stop completely if the pain stays below five out of ten and is back to baseline the next morning.
• Cut volume for a few weeks instead of stopping: what the tissue needs is load, just less of it.
• Give it time. This is measured in weeks, not days.
