Knee Osteoarthritis Physiotherapy — Erina & Central Coast
A deep ache in the knee, stiffness that's worse in the morning, and a gradual reduction in how far you can comfortably walk are all common signs of knee osteoarthritis. It's a genuinely common and manageable condition, and while it can't be reversed, the right approach makes a real difference to how it affects your daily life.
What Is Knee Osteoarthritis?
Osteoarthritis involves gradual wear of the cartilage that cushions the knee joint, along with changes to the surrounding bone and joint lining over time. This can lead to pain, stiffness, and sometimes a grinding or catching sensation with movement. It tends to develop gradually over years, and the degree of change on an X-ray doesn't always match how much pain or limitation someone actually experiences.
This last point genuinely matters — some people with significant changes on imaging have relatively mild symptoms, while others with milder imaging findings are more limited in daily function. It's part of why we focus so heavily on your actual movement, strength, and goals during assessment, rather than treating a scan report as the whole story.
What Causes It?
Knee osteoarthritis is more common in people over 50, and risk is increased by previous knee injury, particularly ligament or meniscus injuries, family history, and higher body weight, which increases load through the joint over time. Occupations or sports involving heavy or repetitive loading of the knee, particularly kneeling and squatting, can also contribute to changes developing earlier than they otherwise might.
Common Symptoms
A deep ache within the knee joint
Stiffness, particularly first thing in the morning or after sitting
A grinding or catching sensation with movement
Gradually reduced walking tolerance or difficulty with stairs
Occasional swelling around the joint during flare-ups
How We Diagnose It
Diagnosis is based on your history, the pattern of your symptoms, and a hands-on assessment of your knee's movement and strength. X-rays can help confirm the diagnosis and give a sense of severity, though we focus heavily on your actual function and goals rather than the image alone, since these don't always correlate closely.
How Physiotherapy Helps
While osteoarthritis can't be reversed, physiotherapy makes a genuine difference to how it affects your day-to-day life. Treatment typically includes a targeted strengthening program for the muscles supporting the knee, particularly the quads and glutes, along with gentle range of motion work to manage stiffness and practical strategies for pacing activities to reduce flare-ups without unnecessarily limiting what you do.
We'll also help you understand your specific flare-up pattern — what tends to aggravate things and what settles them — so you have a clear, practical plan for managing symptoms yourself between flare-ups. For more advanced or persistent cases significantly affecting function, we can discuss further options with your GP, including referral to a specialist if joint replacement becomes a relevant conversation down the track.
Self-Care While You Wait For Your Appointment
Gentle, regular movement tends to help more than rest for arthritic joints, even though it can feel counterintuitive when the joint is stiff and sore. Heat can be helpful for easing morning stiffness, while ice is often more useful after a flare-up from overuse. Pacing heavier or repetitive tasks across the day, rather than doing them all at once, can also help reduce the intensity of flare-ups.
Frequently Asked Questions
Can knee osteoarthritis be cured?
No, but it can be well managed. Most people maintain good function and manageable pain levels long-term with the right combination of strengthening, activity pacing, and flare-up management.
Will exercise make my arthritis worse?
The right type and amount of exercise generally helps rather than harms an arthritic joint, by maintaining strength and movement. We'll guide you on what's appropriate for your specific knee.
Will I eventually need a knee replacement?
Not necessarily. Many people manage well long-term without surgery. It's occasionally considered for more advanced cases significantly affecting function and quality of life, and we can help guide that conversation if it becomes relevant.
