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.
