Knee osteoarthritis is a degenerative condition that affects millions of people worldwide. When diagnosed with knee osteoarthritis, it is natural to feel concerned and wonder if engaging in physical activity is still possible. Although this condition can be limiting, staying active and performing appropriate exercises can be beneficial in improving mobility and reducing pain. In this article, we will address the relationship between knee osteoarthritis and physical activity, the recommended exercises, and the considerations to maintain an active and healthy lifestyle.
What is Knee Osteoarthritis?
Knee osteoarthritis, also known as knee osteoarthrosis, is a degenerative disease that affects the cartilage covering the knee joints. Over time, the cartilage wears away, causing the bones to rub against each other, leading to pain, stiffness, and inflammation in the knee.
This condition can be caused by various factors such as aging, wear and tear from repetitive use, previous knee injuries, or genetic factors. Knee osteoarthritis can affect the quality of life of those who suffer from it, limiting their ability to perform everyday activities and sports.
Can I Engage in Physical Activity with Knee Osteoarthritis?
The answer is yes, but it is essential to do so with caution and by adapting physical activity to individual needs and capabilities. Although knee osteoarthritis may limit mobility and cause pain, staying active can have several benefits for those who have the condition.
- Muscle Strengthening: Performing strength exercises can help improve knee stability and support, reducing pain and enhancing mobility. Strong leg muscles can better absorb impact and protect the knee joint.
- Maintaining Flexibility: Knee osteoarthritis can lead to joint stiffness, making mobility challenging. Regular stretching exercises can help maintain flexibility and improve the range of motion in the knee.
- Weight Management: Maintaining a healthy weight is crucial in reducing pressure on the knees. Regular physical activity combined with a balanced diet can help control body weight, which can alleviate the load on the affected knee.
- Emotional Benefits: Physical activity can release endorphins, the so-called “happiness hormones,” which can improve mood and help reduce stress associated with pain and limited mobility.

Recommended Exercises for Knee Osteoarthritis
It is essential to consider that not all exercises are suitable for individuals with knee osteoarthritis. Some high-impact exercises or those involving abrupt movements can exacerbate the condition. Here are some recommended exercises for knee osteoarthritis:
1. Walking:
Walking is an excellent low-impact activity that helps improve knee mobility and strengthens leg muscles.
2. Swimming:
Swimming is a low-impact exercise that works the entire body without putting pressure on the joints. Swimming or performing aquatic exercises can be beneficial in enhancing knee flexibility and strength.
3. Cycling:
Cycling on a stationary bike or a leisure bike is a low-impact option that allows for improved knee range of motion.
4. Strengthening Exercises:
Exercises such as squats, leg lifts, and knee extensions can be useful in strengthening leg muscles and improving knee support.
5. Stretching Exercises:
Gentle stretches like quadriceps stretches and hamstring stretches can help maintain knee flexibility.
Care During Physical Activity with Knee Osteoarthritis
It is always essential to consider some care while engaging in physical activity with knee osteoarthritis:
1. Consult with a Healthcare Professional:
Before starting any exercise program, it is essential to consult with a doctor or physical therapist to obtain an evaluation and specific recommendations for your case.
2. Proper Warm-up:
Perform warm-up exercises before each exercise session to prepare the muscles and joints for the effort.
3. Avoid Overexertion:
Listen to your body and avoid exercises or activities that generate intense pain or discomfort in the knee.
4. Gradually Increase Intensity:
Always increase the intensity and duration of exercises gradually to prevent injuries.
5. Rest and Recovery:
Give your body time to recover after each exercise session. If you experience pain or swelling, rest and apply ice to the affected area.

Conclusions
Knee osteoarthritis can be a challenging condition, but it does not mean you have to give up physical activity. Staying active with knee osteoarthritis can have multiple benefits, such as muscle strengthening, flexibility improvement, and body weight control. However, it is essential to do so with caution and following the recommendations of a healthcare professional.
Remember that each person is unique, and what works for one may not be suitable for another. Always consult with a doctor or physical therapist before starting any exercise program, and listen to your body during physical activity. With the right approach and proper care, you can continue to enjoy physical activity and maintain an active and healthy lifestyle despite knee osteoarthritis.
