Introduction
Knee arthritis is a widespread condition affecting millions of people worldwide, significantly impacting mobility and quality of life. Whether you’re newly diagnosed or have been living with arthritis for years, you may have many questions about managing pain, staying active, and protecting your knees for the long term.
In this comprehensive guide, we’ll address 10 of the most frequently asked questions about knee arthritis, helping you gain clarity and take control of your health.
1. What Are the Early Signs of Knee Arthritis?
Knee arthritis often develops gradually, with subtle signs that can be easy to dismiss in the early stages. Key symptoms include:
- Stiffness – Often noticeable in the morning or after prolonged periods of inactivity.
- Mild swelling – The knee may appear slightly puffy or swollen due to inflammation.
- Aching pain – This discomfort often worsens with activity and improves with rest.
- Grinding or clicking sensations (crepitus) – A feeling of friction within the joint when moving.
- Decreased flexibility – You may find it harder to fully bend or straighten your knee.
Recognising these early warning signs allows you to take proactive steps to slow progression and protect your knee health.

2. What Causes Knee Arthritis?
Knee arthritis can develop due to several contributing factors, including:
- Age – Wear and tear accumulate over time, increasing the risk.
- Previous injuries – Old injuries, such as ligament tears or fractures, can lead to arthritis later.
- Genetics – If knee arthritis runs in your family, you may have a higher risk.
- Obesity – Carrying excess weight increases stress on the knee joints.
- Repetitive stress – Occupations or activities that involve excessive knee use can accelerate cartilage breakdown.
Understanding these risk factors can help you take preventive measures to slow the onset and progression of arthritis.
3. What Are the Best Exercises for Knee Arthritis?
Exercise is crucial for maintaining knee function and managing arthritis symptoms. However, finding the right balance is key, as certain exercises can aggravate your condition.
Here are some effective exercises that strengthen your knee without causing flare-ups:
- Quadriceps Strengthening – Leg lifts and wall sits improve knee support.
- Low-Impact Cardio – Walking, swimming, and cycling keep joints mobile.
- Stretching Exercises – Gentle hamstring and calf stretches enhance flexibility.
