Your Knee Pain Isn't Going to Sort Itself Out. Here's What's Actually Going On
Knee pain has a way of quietly taking over your life. Getting up from a chair becomes a mission. Stairs feel like a test. You find yourself favouring one leg without even thinking about it. If that sounds familiar, you are not alone — and more importantly, there is usually a very clear reason it is happening.

Why Knee Pain Is So Common
The knee is one of the most used joints in the body. It bears your full body weight with every step, bend, and twist. It relies on a complex system of cartilage, tendons, ligaments, and muscles all working in coordination. When any part of that system is under stress or not working properly, the knee is usually the first place you feel it.
What makes knee pain so frustrating is that it rarely stays the same. It might ease off during a walk and then spike when you sit down for too long. It might be fine at rest but unbearable on stairs. That inconsistency is actually a clue to what is happening — and it is exactly the kind of information a physio uses to work out what is going on.
Common Symptoms of Knee Pain
Knee pain presents differently depending on the cause. Common symptoms include:
- Pain at the front of the knee, particularly when climbing stairs or after sitting for long periods
- Aching or stiffness inside or outside the joint
- Swelling or a feeling of the knee being puffy or full
- Clicking, grinding, or locking sensations
- Pain that is worse first thing in the morning and improves once you get moving
- A feeling of instability or the knee wanting to give way
- Pain during or after exercise that settles with rest
What Causes Knee Pain?
There is no single cause of knee pain. The most common causes we see at PHYZFIT include:
Patellofemoral Pain (Runner's Knee)
Pain at the front of the knee around or behind the kneecap is extremely common, especially in people who run, cycle, or spend long periods sitting. It is often caused by how the kneecap tracks through its groove, which is influenced by hip strength, quad function, and foot mechanics.
IT Band Syndrome
The iliotibial band is a thick band of tissue running down the outside of the thigh to the knee. When it becomes irritated, it causes sharp or burning pain on the outer side of the knee, typically during running or walking downhill. It is often linked to weakness in the hip rather than a problem in the knee itself.
Meniscus Irritation or Injury
The menisci are C-shaped pieces of cartilage that cushion the knee joint. They can become irritated through repetitive load or damaged through sudden twisting movements. Symptoms often include pain on twisting, difficulty fully straightening or bending the knee, and sometimes clicking or locking.
Osteoarthritis
Knee osteoarthritis involves the gradual wearing of the cartilage that cushions the joint. It tends to cause stiffness and aching that is worse in the morning, improves with movement, and then flares again after prolonged activity. It is more common from middle age onward, but it is not a life sentence — physiotherapy has strong evidence for helping manage symptoms and improve function.
Patellar Tendinopathy
The patellar tendon connects the kneecap to the shinbone and plays a critical role in jumping, running, and squatting movements. When it is overloaded — usually through a sudden increase in training load — it becomes painful and stiff, particularly first thing in the morning or at the start of activity.
Struggling with knee pain?
Our physio team at PHYZFIT can assess what is actually driving your symptoms and build a plan to support your recovery. No referral needed.
Book an AssessmentWhen the Knee Is Not Really the Problem
This is one of the most important things to understand about knee pain: the knee is often not where the problem starts. The knee is caught between the hip above and the ankle and foot below, and weakness or stiffness anywhere in that chain can change how force travels through the knee joint.
Weak glutes, poor hip control, or altered foot mechanics can all place extra stress on the knee even when you are just walking. This is why treating only the knee often does not resolve the problem long term — a thorough assessment needs to look at the whole lower limb.
This is also why knee pain can seem to come out of nowhere. You have not done anything unusual, but small imbalances or weaknesses that were previously being compensated for have finally reached a tipping point. Once we identify where the load is coming from, it gives us a clear direction for treatment.
How We Treat Knee Pain at PHYZFIT
Our approach starts with understanding exactly what is happening in your specific case. We assess not just the knee but everything that influences it — your hip strength, movement patterns, footwear, activity levels, and history. From there, we build a plan that is specific to you.
Treatment may include hands on therapy to address joint stiffness and reduce irritation, a targeted strengthening program to address the underlying cause, guidance on load management so you can stay as active as possible while your knee settles, and if needed, advice on footwear or orthotics.
What to Expect When You Come In
We assess your knee, hip, and lower limb mechanics to understand exactly where the load is coming from and what is driving your pain.
Manual therapy to address joint stiffness, reduce irritation around the knee, and restore movement that has been restricted by pain or inflammation.
A progressive exercise program targeting the muscles that support and protect the knee, with a focus on the hips and glutes as well as the quads and calves.
A clear plan for returning to the things you want to do — sport, exercise, work, or just getting through the day without your knee holding you back.
What You Should Not Do With Knee Pain
- Do not ignore it and push through training as normal — loading an irritated knee without addressing the cause tends to make things worse
- Do not rest completely for weeks on end — the muscles that support the knee quickly weaken with inactivity, which can slow your recovery
- Do not assume it is just your age — knee pain at any age is worth understanding properly
- Do not rely solely on anti-inflammatories or ice as a long term strategy — these can help manage symptoms but do not address the underlying cause
- Do not avoid activity altogether — staying gently active with appropriate guidance is almost always better for knee recovery than complete rest
⚠️ Seek Urgent Medical Attention If You Experience:
- Significant swelling that develops suddenly after a knock or fall
- A loud pop followed by immediate inability to bear weight
- The knee locking completely and being unable to straighten
- Severe bruising, deformity, or intense warmth around the joint
- Knee pain accompanied by fever or feeling unwell

How long does knee pain take to get better with physio?
It depends on what is causing your knee pain and how long it has been going on. Acute pain from a recent irritation often responds quickly, sometimes within a few sessions. Chronic issues or structural changes like osteoarthritis take longer to manage, but most people see meaningful improvement within 6 to 8 weeks of consistent treatment and exercise. Your physio will give you a clearer picture at your first appointment.
Should I rest completely when my knee is sore?
Not usually. Complete rest tends to weaken the muscles that support the knee, which can actually slow recovery. The goal is to find the right level of activity for where your knee is right now — staying as active as you can within a comfortable range, while reducing activities that aggravate symptoms. A physio can help you work out exactly what that looks like for your situation.
Can physio help with knee osteoarthritis?
Yes. Physiotherapy is one of the most well supported approaches for managing knee osteoarthritis. Exercise-based treatment — particularly strengthening the muscles around the knee and hip — has strong evidence for reducing pain and improving day to day function. It will not reverse cartilage changes, but it can significantly improve what you are able to do and how you feel.
Do I need an X-ray or MRI before seeing a physio?
In most cases, no. A thorough clinical assessment gives us a lot of information without imaging, and most knee pain does not require a scan before we can start treatment. If imaging is needed, your physio will advise you and can refer you to a GP for the appropriate request. You do not need a referral to see us — just book directly.
Can I keep exercising with knee pain?
Often yes, but it depends on what is causing the pain. Some activities may need to be modified or temporarily reduced while others are perfectly fine to continue. A physio can advise you on exactly what to keep doing, what to change, and what to avoid for now — so you can stay active and support your recovery at the same time.
Does Medicare cover physiotherapy at PHYZFIT?
Yes, if you have a Chronic Disease Management (CDM) plan from your GP, you may be eligible for Medicare-rebated physiotherapy sessions. We also accept most private health funds. Contact us at admin@phyzfit.com.au or call (02) 8021 0969 and we can help you work out what you are covered for.
