Knee Osteoarthritis.How we help.
Knee osteoarthritis builds up slowly, and it often shows up first in ordinary moments. Getting up from the floor after sitting cross-legged, the first few steps after a long sit, the stairs up to your flat or a walk round a Jaipur market. One knee may be involved, or both. Some days feel easy and others feel stiff and sore. What an X-ray shows does not always match how much your knee hurts.
How we help
- An assessment of knee movement, thigh and hip strength, and how far you can currently walk, stand and manage stairs
- A graded strengthening programme for the thigh, hip and calf muscles that support the knee
- Practice with the movements that have become awkward: stairs, getting out of a chair, squatting, getting up from the floor
- A plain explanation of what osteoarthritis means for your knee, so you know which activities to keep and how to pace them
What to expect
Your first visit starts with a conversation about which activities have become hard and what you want to get back to, followed by a check of knee movement, lower-limb strength, walking, stairs and balance. Your physiotherapist explains in plain language what the examination found, then sets out a starting programme and how it will be progressed as your knee responds. Where it suits your case, they may also suggest options such as TECAR, Class IV laser, dry needling or cupping, and will talk you through what each one involves before you decide.
What knee osteoarthritis is
The knee is formed by the femur, the tibia and the patella, and it is supported by cartilage, ligaments, tendons, muscles and other joint tissues.
Osteoarthritis involves the whole joint rather than cartilage loss alone. Changes can occur in the articular cartilage, the bone underneath it, the joint lining and the surrounding tissues. The joint may gradually become less tolerant of certain physical loads, and that can show up as pain, stiffness and reduced function.
It can develop gradually and may affect one knee or both. Symptoms can fluctuate over time, with spells when the knee feels reasonably comfortable and spells when pain or stiffness increases. Osteoarthritis can affect other joints too. What follows is about the knee.
The amount of structural change visible on an X-ray does not always correspond to the amount of pain you feel. Some people have substantial changes on imaging with few symptoms. Others have significant pain alongside comparatively modest imaging findings. That is why management looks at symptoms, strength, movement, physical capacity and quality of life, rather than at the appearance of the joint alone.
A diagnosis of knee osteoarthritis does not automatically mean the joint will deteriorate to the point where surgery is required. Many people can manage symptoms through exercise, physical activity, weight management where appropriate and other conservative strategies.
Why it develops
Knee osteoarthritis develops through a combination of biological, mechanical and individual factors rather than one single cause. The factors associated with its development or progression:
- Age. The likelihood of osteoarthritis increases as we get older.
- A previous knee injury. ACL injuries, meniscal injuries, fractures and other significant knee trauma can increase the long-term risk.
- Repeated joint loading. Certain occupational or sporting demands may contribute to cumulative stress on the knee.
- Reduced muscle strength. Lower levels of lower-limb strength can reduce the ability of the knee to tolerate everyday physical demands.
- Body weight. Higher body mass can increase the mechanical demands placed on the knee during weight-bearing activities, and may also influence joint biology.
- Genetic and biological factors. Individual susceptibility can influence how joint tissues respond to ageing and to mechanical loading.
- Previous surgery. Certain knee operations, particularly after a significant injury, may influence the longer-term development of joint changes.
It helps to put aside the phrase bone on bone. Osteoarthritis is more complicated than inevitable joint destruction, and the presence of structural change does not determine how active or how capable you can remain.
How symptoms show up day to day
Symptoms can vary considerably from one person to the next. The ones commonly reported:
- Knee pain while walking, and pain climbing or descending stairs.
- Discomfort when squatting or kneeling, and pain after prolonged activity.
- Stiffness, particularly after a period of sitting still, and swelling around the knee.
- Reduced knee movement, difficulty getting up from a chair, and reduced walking tolerance.
- Weakness in the thigh or lower limb, and clicking or other joint sounds.
- Less confidence using the knee, and difficulty taking part in activities you used to enjoy.
Some people have relatively mild symptoms despite significant joint changes, while others may have substantial pain and functional limitation. Symptoms can also shift with activity, physical capacity, sleep and general health, which is why a bad patch does not always mean the joint itself has changed.
A few things sit outside that range of ordinary variation. Persistent or significant swelling, substantial instability, locking, unexplained severe pain, or symptoms accompanied by fever or systemic illness should have appropriate medical assessment.
How rehabilitation is built
An osteoarthritic knee is not treated here as a damaged joint that has to be shielded from movement. The starting questions are what your knee currently tolerates, what it needs to tolerate, and what you want to be able to do again.
The assessment takes in pain behaviour, knee movement, lower-limb strength, functional capacity, activity levels, previous injuries and your own goals. The programme is built from that, then progressed as your symptoms and your capacity change.
Where you want to stay active, that may mean building strength and returning gradually to walking, running, gym training or recreational sport. Where osteoarthritis is affecting everyday life, the emphasis may shift to walking capacity, stairs, balance, strength and independence.
A good part of the work is simply understanding the condition. An osteoarthritis diagnosis does not mean your knee is fragile or that movement should be avoided. The aim is to build capacity, confidence and independence while respecting what the knee will take today.
Diagnosis, imaging, medication, injections and any decision about knee replacement surgery rest with a doctor or an orthopaedic surgeon. Physiotherapy sits alongside that decision, before it and after it, rather than in place of it.
Common questions
Should I see a physiotherapist for knee arthritis?
It is a reasonable place to start when pain or stiffness is limiting your walking, your stairs or your daily activities. A physiotherapist can assess your pain, knee movement, strength and walking, then build an exercise plan around what your knee tolerates and what your day asks of it.
Is there a single best treatment for knee osteoarthritis?
No single treatment is established as the best one. Management usually combines exercise, activity modification, weight management where appropriate, pain management and physiotherapy. Which mix suits you depends on how severe your symptoms are and what your daily activities ask of the knee.
What does physiotherapy for knee osteoarthritis involve?
An assessment comes first. What commonly follows is strengthening for the quadriceps, hamstrings, hip and calf muscles, along with low-impact aerobic exercise and mobility work, progressed gradually. Which of those suit you comes out of the assessment rather than a standard sheet, and they are reviewed as your knee responds.
Should I keep walking if I have knee osteoarthritis?
In most cases regular walking is worthwhile if the knee tolerates it. Start at a comfortable level and build the duration gradually while watching pain and swelling afterwards. Your physiotherapist can help you pick a starting point and a rate of increase that fits your current capacity.
Can physiotherapy help me avoid a knee replacement?
Physiotherapy works on pain, strength, movement and function, and for some people that may be enough to delay or avoid an operation. It is not something anyone can promise you, and it is not a call physiotherapy makes. Either way the work is useful, both while surgery is being considered and after it.
Does knee osteoarthritis always get worse?
Not automatically. A diagnosis does not mean the joint will inevitably deteriorate to the point where surgery is required, and the amount of change on a scan does not decide how active you can be. Symptoms can fluctuate, with easier spells and harder ones.
