Overview
Osteoarthritis is the most common form of arthritis and often affects the knees. As the protective cartilage wears down, the bones rub together, causing pain and stiffness. Treatment can relieve symptoms and help you stay active.
Symptoms
- Knee pain that worsens with activity, stairs or kneeling
- Stiffness, especially after rest or in the morning
- Swelling
- A grating or cracking sensation
- Reduced movement or a feeling of instability
Causes and risk factors
- Older age
- Excess body weight
- A previous knee injury
- Female sex
- A family history of osteoarthritis
Diagnosis
Diagnosis is based on symptoms, examination and X-rays of the knee.
Treatment
Treatment includes exercise and physiotherapy, weight loss, pain relief and walking aids. Injections may help some patients. Knee replacement surgery may be recommended for severe arthritis when other treatments no longer help.
When to see a doctor
See a doctor if knee pain limits your daily activities or does not improve. Seek care promptly for a hot, very swollen knee, especially with fever.
