Knee Osteoarthritis Physiotherapy
Structured physiotherapy to help manage knee osteoarthritis symptoms and support joint function.
Knee osteoarthritis can lead to stiffness, aching and reduced confidence in daily movement. Physiotherapy aims to help manage symptoms, build supportive strength around the joint, and may help delay or reduce the need for surgery in some people, depending on individual circumstances.
Overview
What Is Knee Osteoarthritis Physiotherapy?
Osteoarthritis of the knee is a condition in which the cartilage cushioning the joint gradually changes over time, which may lead to pain, stiffness and swelling, particularly with weight-bearing activities. It is one of the most common causes of knee discomfort in older adults, though it can also affect younger people, particularly after previous joint injury.
Symptoms often develop gradually and can fluctuate, sometimes feeling worse after periods of activity or inactivity. While the joint changes associated with osteoarthritis cannot be reversed, physiotherapy focuses on what can be influenced: muscle strength, joint mobility, movement patterns and overall function.
A personalised physiotherapy programme, combined with appropriate activity and lifestyle adjustments, may help many people manage symptoms and remain active. Treatment depends on the individual, including the severity of joint changes, general health and personal goals.
Signs to notice
Common Symptoms & Signs
Not everyone experiences all of these, and similar symptoms can have different causes. An assessment can help determine what is relevant for you.
Knee stiffness
Stiffness that is often most noticeable first thing in the morning or after periods of sitting.
Aching pain
A deep ache around the knee that may worsen with activity such as walking or climbing stairs.
Swelling
Mild to moderate swelling around the joint, particularly after increased activity.
Reduced range of movement
Difficulty fully bending or straightening the knee compared with before.
A grinding or catching sensation
Some people notice a grinding, clicking or catching feeling with movement.
Reduced walking tolerance
A sense that walking distances or standing for long periods has become more difficult.
Understanding it
Why Does This Happen?
Knee osteoarthritis is generally understood to develop from a combination of factors including age-related joint changes, previous injury, repetitive joint loading, body weight and genetic predisposition. Over time, changes in the joint cartilage and surrounding structures may alter how the joint moves and tolerates load.
Muscle weakness, particularly around the thigh, can also influence symptoms, as reduced muscular support may increase strain on the joint itself. This is one of the key reasons targeted strengthening forms a central part of physiotherapy management.
Contributing factors
Common Causes & Contributing Factors
Age-related joint changes
Natural changes in cartilage and joint structures over time are commonly associated with osteoarthritis.
Previous knee injury
Earlier ligament, meniscus or joint injuries may increase the likelihood of developing osteoarthritis later.
Repetitive joint loading
Occupations or activities involving repeated kneeling, squatting or heavy loading may contribute over time.
Muscle weakness
Reduced strength around the knee, particularly in the thigh muscles, may increase joint strain.
Body weight and general health
Higher body weight can increase load through the knee joint, potentially contributing to symptom progression.
Suitability
Who May Benefit From This Service?
Older adults
Individuals experiencing gradual knee stiffness and aching associated with age-related changes.

Timing
When Should You Consider Physiotherapy?
- Ongoing knee pain or stiffness affecting daily activities.
- Difficulty with stairs, walking or standing for extended periods.
- Swelling that recurs after activity.
- A feeling of the knee being less stable or reliable than before.
- You are considering knee surgery and want to explore other options first.
- You have been advised you may need surgery in the future and want to optimise strength beforehand.
- Symptoms are limiting participation in activities you enjoy.
- You want guidance on safe exercise given your joint symptoms.
An assessment can help determine whether physiotherapy is appropriate for your situation, or whether another form of medical review would be more suitable first.
Treatment options
How Can Physiotherapy Help?
Physiotherapy for knee osteoarthritis generally focuses on strengthening the muscles supporting the joint, improving mobility, and helping you manage symptoms during daily activities.
Comprehensive assessment
Evaluating knee movement, strength, gait and overall function to guide the plan.
Targeted strengthening
Exercises focused on the thigh and hip muscles to help support the knee joint.
Range of movement exercises
Gentle mobility work aimed at maintaining or improving joint flexibility.
Pain management strategies
Techniques and advice that may help manage day-to-day symptoms.
Gait and movement retraining
Guidance on walking patterns and movement mechanics to reduce unnecessary strain.
Weight-bearing activity advice
Recommendations on suitable low-impact activities such as swimming or cycling.
Education on the condition
Clear explanation of osteoarthritis and realistic expectations for management.
Support for pre- or post-surgical care
Guidance for those preparing for or recovering from knee surgery, if relevant.
Not every patient receives every technique — the plan depends on assessment findings, personal goals and how you respond over time.
Step by step

In practice
What Your Rehabilitation May Involve
- Quadriceps and hamstring strengthening exercises.
- Hip strengthening to support overall knee alignment.
- Gentle range of movement exercises for the knee joint.
- Balance and proprioception exercises where appropriate.
- Low-impact aerobic conditioning such as cycling or swimming.
- Gait retraining and walking aid advice if needed.
- Guidance on pacing activity to avoid symptom flare-ups.
- A structured home exercise programme.
Rehabilitation differs from person to person; pace and content are adjusted to your condition, comfort and progress.
Risk reduction
How Can You Reduce the Risk of This Problem?
- Maintain regular low-impact physical activity.
- Build and maintain thigh and hip muscle strength.
- Manage body weight through activity and diet where relevant.
- Avoid prolonged periods of complete inactivity.
- Use supportive, well-cushioned footwear.
- Address minor knee symptoms early rather than pushing through pain.
- Warm up before exercise and progress activity levels gradually.
- Attend regular check-ins if you have known joint changes.
Sensible prevention can lower risk, but it cannot remove it entirely — symptoms that return or persist are worth having reviewed.

Good to know
Why Professional Assessment Matters
Because knee osteoarthritis can vary widely in severity and presentation between individuals, professional assessment can help determine an appropriate and realistic management plan tailored to your specific joint findings and goals.
Physiotherapy assessment can also help identify when further medical input, such as imaging or specialist referral, may be appropriate alongside ongoing rehabilitation.
When Should You Seek Medical Attention?
Physiotherapy is not a substitute for urgent medical evaluation. Please contact a doctor or emergency service if you notice:
- Sudden, severe knee pain and swelling following an injury.
- Inability to bear any weight on the leg.
- Signs of infection such as redness, warmth, fever or feeling generally unwell.
- Significant knee deformity or locking of the joint.
- Rapidly worsening pain not explained by recent activity.
Questions
Frequently Asked Questions
Physiotherapy may help manage symptoms by improving strength, mobility and movement patterns around the joint. It does not reverse joint changes, but many people find it supports better function and comfort, depending on individual factors.
Appropriately guided exercise is generally considered supportive rather than harmful for most people with knee osteoarthritis. A physiotherapist can help tailor activity levels to your specific joint and symptom pattern.
For some people, physiotherapy may help delay or reduce the need for surgery by improving strength and function, though this depends on the severity of joint changes and individual response to treatment. It is not guaranteed for everyone.
Low-impact activities such as swimming, cycling and walking are often well tolerated, though suitability varies between individuals. A physiotherapist can advise on activities appropriate for your specific situation.
Not necessarily. Many people begin physiotherapy based on clinical assessment, though imaging may sometimes be recommended by your doctor if symptoms are unclear or not responding as expected.
This varies between individuals depending on symptom severity, consistency with exercise and overall health. Some people notice gradual changes over several weeks of a structured programme.
Walking is generally not considered harmful and can be a useful low-impact activity for many people, though pacing and appropriate footwear may help manage comfort during longer distances.
Yes, physiotherapy also plays a role in post-surgical rehabilitation, focusing on restoring movement and strength after the procedure, guided by your surgical team's advice.
