See how osteoarthritis affects the knee and why tailored strengthening and everyday movement are central to care.
What is it?
Knee osteoarthritis affects the whole joint, including cartilage, bone and surrounding tissues. Pain may fluctuate rather than worsen steadily. A scan does not tell the whole story: your symptoms, function and goals help guide treatment.
- Pain with walking or stairs
- Stiffness after sitting
- Occasional swelling or reduced movement
How physiotherapy may help
Strengthen the leg
Select knee and hip exercises that are achievable now and progress over time.
Keep active
Find aerobic activity you enjoy, such as walking, cycling or water-based exercise.
Manage flare-ups
Adjust the load, pace demanding tasks and plan a gradual return.
Everyday approach
Exercise may initially feel uncomfortable, but a tailored plan can improve pain and function. If weight management is relevant, seek supportive advice rather than extreme diets. A walking aid may help when walking is difficult.
What to keep in mind
Physiotherapy does not regrow cartilage or guarantee avoidance of surgery. If pain substantially affects life despite appropriate non-surgical care, discuss further options with your GP. Treatment choices should fit your needs and preferences.
