If you spend any amount of time running around Adelaide, whether you’re cruising along the Glenelg foreshore, hitting the trails near Modbury, or training for the next Adelaide Marathon, you’ve probably heard the term runner’s knee. It’s one of the most common sources of knee pain in runners of all levels, and despite the name, it doesn’t just affect elite athletes. Weekend joggers, new runners, and even seasoned marathoners all end up in our Pod Fit Podiatry clinics asking the same question:
“Why does my knee hurt when I run?”
Let’s break down exactly what runner’s knee is, why it happens, and most importantly how you can recover and get back to doing what you love.
What Is Runner’s Knee?
Runner’s knee is the everyday name for Patellofemoral Pain Syndrome (PFPS). It’s an irritation of the joint between your kneecap (patella) and your thigh bone (femur). When this joint stops moving smoothly or experiences too much load, it becomes painful and is most commonly felt at the front of the knee.
You don’t have to be running 100 km a week to get it. Even moderate runners heading out a few times a week around the Torrens or Henley Beach can develop PFPS if movement patterns, training loads, or footwear aren’t aligned with what your body needs.
Why Runner’s Knee Happens
At Pod Fit Podiatry, we see hundreds of runners every year across our Glenelg, Findon, and Modbury clinics, and runner’s knee consistently shows up for the same handful of reasons. Often, it’s not just one thing but a combination of factors:
- 1. Overload: Doing Too Much, Too Soon
A classic example is ramping up mileage quickly, like preparing for the City to Bay or Adelaide Marathon. The knee joint suddenly cops more load than it’s conditioned for, and the tissues get irritated. - 2. Weakness Through the Hips and Quads
The knee is heavily influenced by the muscles above it. Weak glutes or quadriceps mean the patella doesn’t track smoothly, leading to that familiar dull ache under or around the kneecap. - 3. Foot Mechanics and Running Technique
Flat feet, rolling in too much (pronation), stiff ankles, or running with a long overstride can all increase knee stress.
This is where our Zebris treadmill gait analysis is a game changer. It measures pressure, timing, symmetry, and foot behaviour during your run, showing exactly what your joints are doing with every step. - 4. Poor Footwear Choices
Old, worn-out running shoes, or even brand-new ones that aren’t suited to your gait, can overload the knee. Many runners unknowingly pick shoes based on comfort alone, not biomechanics. - 5. Reduced Mobility
Tight quads, calves, or hips can pull the knee joint into disadvantageous positions during movement, increasing friction and pain.
Symptoms of Runner’s Knee
Most runners describe:
- A dull ache at the front of the knee
- Pain when running, squatting, walking stairs, or sitting for long periods
- Clicking or grinding behind the kneecap
- Pain that warms up slightly but flares again after activity
If you’ve been training around the coastal paths at Glenelg or pushing long runs through the linear trails near Modbury and the knee starts to ache, it’s likely PFPS.
How We Diagnose Runner’s Knee at Pod Fit Podiatry
A thorough assessment is everything. At Pod Fit Podiatry we don’t guess, we measure.
Your appointment includes:
1. A Full Lower Limb Assessment
We look at mobility, strength, joint control, and your injury history.
2. Pressure Plate & Zebris Treadmill Running Assessment
This is where we shine. Our Zebris treadmill is the only one of its kind in South Australia and gives us data no regular treadmill can provide. You’ll run while thousands of sensors measure:
- Step length
- Impact forces
- Load distribution
- Cadence
- Foot strike patterns
- Left–right asymmetries
- Timing differences through the gait cycle
This detailed insight helps us pinpoint exactly why your knee is under stress.
3. Footwear Review
We look at your current running shoes and how they influence your movement.
No guesswork. No outdated tests. Just precision biomechanics and hands-on clinical experience.
How to Recover From Runner’s Knee
The good news? With proper management, runner’s knee recovers well, and most Adelaide runners return to full training without long-term issues.
Here’s how we guide you back.
1. Load Modification
You don’t always need to stop running entirely. We help you adjust:
- Mileage
- Frequency
- Intensity
- Hills and speed sessions
This keeps you moving while reducing irritation.
2. Targeted Strengthening
Strength is the foundation of recovery. We prescribe exercises specific to what your assessment shows, typically including:
- Hip strength: glute med/min, external rotators
- Quadriceps strength: especially VMO and overall quad capacity
- Calf strength: improves propulsion and reduces overloading up the chain
- Core stability: improves running alignment
These are practical, running-specific movements (not generic rehab exercises you can find on Google).
3. Running Technique Improvements
This is where Adelaide runners get their biggest wins. Using the data from your Zebris analysis, we may adjust:
- Cadence (often increasing steps per minute)
- Foot strike position
- Trunk lean
- Knee angle on landing
Even small tweaks can significantly reduce patellofemoral joint load.
4. Hands-On Treatment When Needed
For painful or tight tissues, we may use:
- Dry needling
- Shockwave therapy
- Deep tissue release
- Mobilisation
These reduce symptoms while the real fix, strengthening and technique, does the long-term work.
5. Footwear and Orthotic Guidance
If your biomechanics contribute to excess knee load, supportive footwear or custom orthotics may help redistribute force. Custom devices can be especially helpful for runners training for events like the Adelaide Marathon, City to Bay, or Yurrebilla Ultra.
6. A Clear Return-to-Run Plan
We don’t just fix the pain, we guide your return to running with:
- Progressive loading
- Measurable strength milestones
- Step-by-step run–walk programmes
- Performance goals tailored to your event
This prevents flare-ups and gives you confidence moving forward.
How Long Does Recovery Take?
Most runners improve within 4-6 weeks with correct management. More persistent cases may take 8-12 weeks, especially if strength deficits or movement issues have been present long-term. The biggest predictor of fast recovery? Accurate diagnosis and a structured plan, not resting and hoping for the best.
When to See a Podiatrist
If your knee pain:
- Has lasted longer than a week
- Is affecting your training consistency
- Feels worse with stairs or sitting
- Keeps flaring up after runs
- Has started limiting speed or distance
Final Thoughts
Runner’s knee can be frustrating, especially if you’re building toward an event like the Adelaide Marathon or just love the mental clarity of your coastal loop runs. The key is understanding why it’s happening and treating the root cause, not just the symptoms. At Pod Fit Podiatry Glenelg, Findon, and Modbury, we specialise in running injuries and use technology like the Zebris treadmill to give you the most accurate diagnosis and personalised plan possible.
If your knee has been holding you back, book a running assessment and let’s get you back on track stronger, more efficient, and pain-free.
