Runner’s Knee: What Causes It & How To Rehab It

Runner’s knee is one of the most common causes of knee pain in active people. If you're currently dealing with symptoms, our Knee Pain Physio in Varsity Lakes page explains how we assess and manage knee pain in more detail.

Despite the name, runner’s knee does not only affect runners.

It is also common in people who:

  • Go to the gym

  • Play sport

  • Hike regularly

  • Increase activity suddenly

  • Spend long periods sitting

The good news is that most cases improve well with the right rehabilitation approach.

What Is Runner’s Knee?

Runner’s knee usually refers to pain around or behind the kneecap.

It is commonly associated with:

  • Patellofemoral pain

  • Load sensitivity around the kneecap

  • Irritation from repetitive loading

Symptoms are often aggravated by:

  • Running

  • Stairs

  • Squatting

  • Lunging

  • Prolonged sitting

Pain may feel sharp during activity or more achy afterwards.

Why Runner’s Knee Develops

Runner’s knee often develops when training load exceeds current capacity.

Common contributing factors include:

  • Sudden increases in running volume

  • Reduced lower limb strength

  • Fatigue and recovery issues

  • Poor tolerance to repetitive loading

  • Returning to activity too quickly after time off

This is where structured Injury Rehabilitation becomes important.

Is It Caused By “Bad Knees”?

Usually not.

Most people with runner’s knee do not have damaged knees.

The issue is more commonly related to:

  • Reduced strength

  • Poor load tolerance

  • Temporary irritation

  • Reduced movement control

This is why complete rest is rarely the best long-term solution.

What Rehab Usually Involves

Effective rehabilitation often includes:

  • Progressive strengthening

  • Quadriceps and glute strengthening

  • Load management

  • Gradual return to running

  • Improving movement control

This is where Exercise-Based Rehabilitation becomes essential.

The goal is not simply to reduce pain.

It is to rebuild the knee’s ability to tolerate load confidently.

Should You Stop Running?

Not always.

In many cases, running can continue with temporary modifications such as:

  • Reducing distance or intensity

  • Avoiding hills temporarily

  • Adjusting running frequency

  • Managing recovery more effectively

The aim is usually to keep some level of activity while symptoms settle and capacity improves.

When Runner’s Knee Keeps Returning

If knee pain repeatedly flares up, it often means:

  • Load progression was too aggressive

  • Strength deficits remain

  • Rehab was stopped too early

  • Capacity has not fully recovered

If symptoms have persisted for several months, a broader Chronic Pain Physiotherapy approach may sometimes help rebuild confidence and tolerance gradually.

When To Get Assessed

Consider booking an assessment if:

  • Pain persists beyond a few weeks

  • Running becomes progressively more painful

  • The knee feels weak or unstable

  • Symptoms continue returning

  • You are unsure how to modify activity safely

A physiotherapy assessment helps identify the factors contributing to your symptoms and guides a structured recovery plan.

Build A Knee That Tolerates Running

Runner’s knee is rarely about damage.

More often, it reflects a temporary mismatch between load and capacity.

With the right rehabilitation approach, most people can return to running and training with improved confidence and reduced risk of recurring pain.

Book your physiotherapy appointment and start building stronger, more resilient knees.
