Knee Osteoarthritis: Causes, Symptoms, and Effective Management with Physiotherapy

What is Knee Osteoarthritis?

Knee osteoarthritis (OA) is a degenerative joint condition that affects millions of people worldwide. It occurs when the protective cartilage that cushions the knee joint wears down over time, leading to pain, stiffness, and reduced mobility. While OA can affect anyone, it is more common in older adults, individuals with previous knee injuries, and those who are overweight or obese.

Causes and Risk Factors of Knee Osteoarthritis

Several factors contribute to the development of knee OA, including:

• Age: The risk increases with age as joint cartilage naturally wears down.

• Obesity: Excess weight puts additional stress on the knee joints, accelerating cartilage breakdown.

• Previous Injuries: Knee injuries, such as ligament tears or fractures, can increase OA risk.

• Genetics: A family history of osteoarthritis may make individuals more susceptible.

• Repetitive Stress: Jobs or activities that involve repetitive knee movements can contribute to OA.

• Muscle Weakness: Weak muscles around the knee fail to provide adequate joint support.

Symptoms of Knee Osteoarthritis

The symptoms of knee OA can vary in severity but typically include:

• Knee pain that worsens with activity and improves with rest

• Stiffness, especially after sitting or sleeping

• Swelling and tenderness around the knee

• Decreased range of motion

• A grinding or clicking sensation in the knee joint

How Physiotherapy Helps in Managing Knee Osteoarthritis

Physiotherapy is one of the most effective, non-surgical treatments for knee osteoarthritis. A physiotherapist will create a tailored treatment plan to reduce pain, improve function, and strengthen the knee.

Benefits of Physiotherapy for Knee OA

• Pain Relief: Targeted exercises and manual therapy can help reduce knee pain.

• Improved Mobility: Stretching and strengthening exercises enhance flexibility and movement.

• Increased Strength: Strengthening the muscles around the knee provides better joint support.

• Better Balance & Stability: Physiotherapy can help prevent falls and further joint damage.

• Avoiding Surgery: Consistent physiotherapy input can delay or even prevent the need for knee replacement surgery.

Common Physiotherapy Techniques for Knee Osteoarthritis

• Strengthening Exercises: Focus on the quadriceps, hamstrings, and calf muscles to support the knee.

• Range of Motion Exercises: Stretching and joint mobilization techniques to improve flexibility.

• Low-Impact Activities: Swimming, cycling, and walking to maintain fitness without stressing the knee.

• Manual Therapy: Hands-on techniques to reduce stiffness and pain.

• Bracing & Support: Knee braces can provide additional stability.

The Role of Weight Loss in Knee Osteoarthritis Management

Maintaining a healthy weight is crucial for managing knee OA. Excess weight increases stress on the knee joints, worsening pain and accelerating cartilage damage.

Benefits of Weight Loss for Knee Osteoarthritis

• Reduced Joint Stress: Every extra kilogram of body weight adds about 4kg of pressure on the knees.

• Pain Reduction: Studies show that losing as little as 5-10% of body weight can significantly reduce knee pain.

• Improved Mobility: Lighter body weight makes it easier to move and exercise

Lifestyle Tips for Managing Knee Osteoarthritis

• Stay Active: Engage in regular, low-impact exercise to keep the joints moving.

• Eat an Anti-Inflammatory Diet: Include foods rich in omega-3s, antioxidants, and fiber.

• Use Supportive Footwear: Well fitting anf supportive shoes can reduce stress on the knees.

• Move! : Avoid prolonged sitting or standing in one position.

• Consider Physiotherapy: Regular sessions with a physiotherapist can help manage symptoms effectively.

Conclusion

Knee osteoarthritis can significantly impact daily life, but with the right management strategies, you can reduce pain and improve mobility. Physiotherapy offers a non-invasive, effective way to strengthen the knee and enhance function, while weight loss plays a key role in reducing joint stress.
