Why Knee Pain Is Common After 40?
Turning 40 doesn’t mean your knees suddenly stop working properly.
Yet for many Australians, this is around the time they begin noticing changes.
Perhaps your knees feel stiff after sitting for a while. Maybe stairs aren’t as comfortable as they used to be, or your knees ache after a weekend of sport or gardening.
These changes can be frustrating, particularly if you’re still active and don’t consider yourself “old”.
The good news is that knee pain after 40 has many possible contributing factors, and age is only one part of the picture.
Understanding what’s influencing your symptoms can help you make informed decisions about staying active and looking after your knees.
Why Do Knees Change Over Time?
Your knees experience thousands of movements every day.
Walking, standing, climbing stairs, squatting, running and getting in and out of a chair all place forces through the joint.
Over many years, the tissues around the knee naturally change.
However, age-related changes don’t automatically mean you’ll develop pain.
Two people of the same age can have very different levels of knee comfort and mobility.
Your activity levels, previous injuries, strength, body weight, work demands and movement patterns can all influence how your knees respond to everyday loading.
Previous Injuries Can Come Back Into the Picture:
An old sporting injury may seem like a distant memory.
Perhaps you injured your knee playing football in your 20s or had a fall while skiing years ago.
Even after recovering, an injury can sometimes influence how you move or load the joint later in life.
This doesn’t mean an old injury will inevitably cause future problems.
It simply makes your injury history useful information when assessing new symptoms.
You May Be Doing More Than You Realise:
Your 40s can be a busy decade.
You may be balancing:
- work
- parenting
- exercise
- household responsibilities
- travel
- recreational sport
Sometimes knee pain appears because your activity level has changed.
For example, you might spend most of the week sitting at work before playing a demanding game of sport on Saturday.
Your knees may be capable of handling the activity, but they may not have recently adapted to that level of loading.
Your Hips and Ankles Can Influence Your Knees:
It’s easy to focus entirely on the painful joint.
But your knee sits between the hip and ankle, so movement at either end can influence how the knee functions.
For example, reduced ankle mobility may affect how you squat or climb stairs.
Similarly, changes in hip strength or control may alter the way your knee moves during walking or exercise.
A useful assessment therefore looks beyond the knee itself.
Is Knee Pain After 40 Always Arthritis?
No.
Osteoarthritis becomes more common with age, but not every painful knee has arthritis.
Knee discomfort may also be associated with:
- muscle weakness
- tendon irritation
- previous injuries
- changes in activity
- reduced mobility
- movement patterns
- other musculoskeletal conditions
Even when osteoarthritis is present, symptoms can vary significantly between individuals.
An assessment can help determine what may be contributing to your particular symptoms.
Stiffness Doesn’t Mean You Should Stop Moving:
When your knees become uncomfortable, it’s tempting to reduce activity.
But avoiding movement completely can lead to reduced strength and confidence.
For many people, appropriate activities such as:
- walking
- swimming
- cycling
- strength training
- mobility exercises
can help maintain fitness and support healthy movement.
The right activity and intensity depend on your symptoms and overall health.
How Chiropractic Care May Help:
Following an appropriate assessment, chiropractic care may form part of a broader approach to managing some types of musculoskeletal knee pain.
Depending on your presentation, care may include:
- manual therapy where appropriate
- soft tissue techniques
- mobility exercises
- strengthening recommendations
- movement retraining
- activity modification advice
- assessment of hip, ankle and lower-limb movement
The aim is to understand the factors contributing to your symptoms and develop a plan suited to your individual needs.
FAQ
Is knee pain normal after 40?
Knee pain becomes more common with age, but persistent pain shouldn’t simply be dismissed as a normal part of getting older. There are many possible contributing factors.
Why do my knees hurt when I climb stairs after 40?
Stairs place greater demands on the muscles and joints around your knees than level walking. Changes in strength, mobility or movement patterns may contribute to discomfort.
Can exercise make knee pain worse after 40?
A sudden increase in exercise or training load may aggravate knee symptoms. Gradually increasing activity and allowing adequate recovery may help your body adapt.
Does knee pain after 40 always mean arthritis?
No. Arthritis is one possible cause, but knee pain can also be influenced by previous injuries, muscle weakness, tendon problems, mobility restrictions and changes in activity.
Can chiropractic care help with knee pain after 40?
Following an appropriate assessment, chiropractic care may help support knee and lower-limb mobility, movement quality and musculoskeletal function as part of an individualised management plan.
