Knee Pain When Walking:
Understanding Knee Osteoarthritis: Causes and Physiotherapy Treatment
Knee pain is one of the most common reasons for reduced mobility, and when that pain occurs specifically during walking, it is often linked to Osteoarthritis (OA). As a “wear and repair” condition, it can make simple daily tasks feel daunting, but with the right clinical approach, you can maintain an active lifestyle.
What is the Condition?
Knee Osteoarthritis is a degenerative joint condition where the protective cartilage that cushions the ends of your bones gradually wears down. Over time, this can lead to the bones rubbing against each other, causing inflammation, bony growths (osteophytes), and discomfort. While it is often associated with aging, it is a manageable condition rather than an inevitable decline.
Common Causes
Osteoarthritis isn’t caused by a single factor but rather a combination of variables:
Age: The risk increases as we get older and our tissues’ ability to repair slows down.
Joint Injury: Previous ligament tears or fractures can lead to OA later in life.
Mechanical Stress: Prolonged repetitive strain or carrying excess body weight increases the load on the joint surface.
Genetics: A family history of joint issues can make some individuals more susceptible
Symptoms to Watch For
The symptoms of knee OA often develop slowly and worsen over time:
Pain during activity: Particularly when walking long distances, climbing stairs, or standing up from a chair.
Joint Stiffness: Most noticeable first thing in the morning or after sitting for long periods.
Crepitus: A grinding, creaking, or popping sensation when moving the knee.
Reduced Range of Motion: Feeling as though you cannot fully bend or straighten your leg.
When to See a Physiotherapist
If your knee pain is dictating your schedule or causing you to avoid activities you love, it’s time for an assessment. You should specifically seek help if:
The pain is becoming more frequent or intense.
Your knee feels “weak” or unstable during walking.
You are relying on over-the-counter painkillers daily to stay mobile.
Physiotherapy Treatment
Physiotherapy is considered a first-line treatment for managing Osteoarthritis symptoms. A clinical plan typically involves:
Joint Loading Management: Learning how to stay active without overloading the joint.
Manual Therapy: Techniques to improve joint lubrication and flexibility.
Soft Tissue Release: Addressing tightness in the hamstrings and calves that often accompanies OA.
Education: Understanding how to “pacing” your activities to prevent flare-ups.
Exercises
Note: Consult a professional to ensure these exercises are appropriate for your specific stage of OA.
Inner Range Quads: Place a rolled-up towel under your knee. Squeeze your thigh muscle to lift your heel off the floor while keeping the back of the knee on the towel.
Seated Leg Extensions: Sitting in a chair, slowly straighten one knee, hold for 3 seconds, and lower it back down.
Clamshells: Lie on your side with knees bent. Lift your top knee while keeping your feet together to strengthen the hip muscles that support the knee.
Take Control of Your Mobility
Osteoarthritis may be a permanent change in the joint, but the pain doesn’t have to be. With a tailored physiotherapy plan, you can strengthen the supporting structures of your knee and get back to walking with confidence.

FAQ
1. Is walking actually good for my knees if I have osteoarthritis?
Yes, movement is essential. Walking helps circulate synovial fluid, which acts as a lubricant for the joint. The key is “motion is lotion”—regular, low-impact walking strengthens the muscles supporting the knee and prevents the joint from becoming even stiffer.
2. Why does my knee feel stiffer in the morning?
This is known as “gel phenomenon.” When the joint is at rest, the lubricating fluid thickens. As you start moving in the morning, the fluid warms up and becomes more viscous, which is why osteoarthritis stiffness typically eases after 10–15 minutes of activity.
3. Will I eventually need a total knee replacement?
Not necessarily. Surgery is usually a last resort. Many people successfully manage osteoarthritis for decades through targeted physiotherapy, weight management, and activity modification, maintaining a high quality of life without ever needing an operation.
4. Can I still exercise if my knee is clicking or popping?
In most cases, yes. If the clicking (crepitus) is not accompanied by sharp pain or sudden swelling, it is generally harmless. It is simply the sound of soft tissues moving over bony surfaces or air bubbles shifting within the joint fluid.
5. Should I use a knee brace for walking?
A brace can be a helpful tool, especially an “unloader” brace designed for osteoarthritis. However, it should be used alongside an exercise program. Relying solely on a brace can cause the supporting muscles to weaken over time.
6. Why does the weather seem to affect my knee pain?
Changes in barometric pressure (often before rain or cold snaps) can cause the tissues within the joint to expand and contract. In an osteoarthritic knee, where nerves are already sensitive, these subtle shifts can lead to increased discomfort.
7. Is cycling better than walking for osteoarthritis?
Cycling is an excellent low-impact alternative because it strengthens the quadriceps without the repetitive “pounding” or vertical impact of walking. Many patients find a combination of both activities provides the best results for joint health.
8. Can physiotherapy actually “regrow” my cartilage?
While physiotherapy cannot regrow worn-out cartilage, it can significantly improve the “environment” of the joint. By strengthening the muscles around the knee, we reduce the amount of direct pressure placed on the remaining cartilage, which slows down further wear.
9. How do I know if I’ve done too much exercise?
A good rule of thumb is the “2-hour pain rule.” If your knee pain is significantly worse two hours after finishing your walk or exercise—or if it is worse the following morning—you likely over-loaded the joint and should adjust your intensity next time.
10. Does losing weight really help knee pain?
Weight management is one of the most effective treatments for knee OA. For every pound of body weight lost, there is a four-fold reduction in the load exerted on the knee joint with every step you take.
