Move to Improve: Why Exercise Takes the Lead in Managing Knee Osteoarthritis, Leaving Injections and Surgeries Behind
The vital role of exercise and lifestyle interventions in preventing total knee replacement (TKR) surgeries for knee osteoarthritis is often understated. Knee osteoarthritis (OA) is a chronic degenerative joint disease affecting millions of individuals worldwide. It is a leading cause of pain, physical disability, and reduced quality of life. While TKR surgeries are commonly performed to alleviate symptoms and improve functionality, the significance of exercise and lifestyle interventions in preventing the need for such invasive procedures cannot be overstated. In this blog, we will explore the importance of exercise and lifestyle interventions in managing knee osteoarthritis and their potential to reduce the reliance on TKR surgeries (which continues to rise as a burden on the healthcare system), supported by evidence from recent research.
Knee osteoarthritis in Australia: A 20-year case study of funding-system failure with poor outcomes.
The study highlights the failures of the current healthcare funding system in Australia and its impact on knee osteoarthritis management. It emphasizes the need for a shift towards non-surgical interventions such as exercise and lifestyle modifications. The research suggests that the reliance on TKR surgeries has increased over the years due to limited access to effective conservative treatments. This finding underscores the importance of exploring alternative approaches to knee osteoarthritis management.
Viscosupplementation for knee osteoarthritis: systematic review and meta-analysis Viscosupplementation involves the injection of hyaluronic acid into the knee joint to alleviate pain and improve joint function. The systematic review and meta-analysis evaluated the efficacy of viscosupplementation as a treatment option for knee osteoarthritis. The study found that viscosupplementation leads to a small reduction in knee osteoarthritis pain compared with placebo, but the difference is less than the minimal clinically important between-group difference. Strong conclusive evidence indicated that viscosupplementation was also associated with an increased risk of serious adverse events. The findings do not support the broad use of viscosupplementation for the treatment of knee osteoarthritis. This suggests that non-surgical interventions, such as exercise and lifestyle modifications, should be considered as first-line approaches for managing knee osteoarthritis.
The Role of Exercise: Regular exercise plays a pivotal role in managing knee osteoarthritis. Scientific evidence consistently demonstrates its effectiveness in reducing pain, improving joint function, and enhancing overall well-being. The following types of exercises have proven beneficial:
Aerobic exercises: Low-impact activities such as swimming, cycling, and brisk walking improve cardiovascular health, aid in weight management, and enhance joint flexibility.
Strength training: Targeted exercises to strengthen the muscles surrounding the knee joint, including the quadriceps and hamstrings, help to support the joint.
Range-of-motion exercises: Gentle stretching exercises increase joint flexibility, reducing stiffness and improving overall functionality.
Lifestyle Modifications: In addition to exercise, certain lifestyle modifications can significantly contribute to the prevention of TKR surgeries for knee osteoarthritis. Consider the following interventions:
Weight management: Maintaining a healthy weight can be beneficial for individuals with knee osteoarthritis. Weight loss through a combination of diet and exercise can alleviate pain and slow disease progression. However, it is important to note that this is not the be-all and end-all to improving knee OA
Education and self-management: Empowering individuals with knowledge about knee osteoarthritis, its symptoms, and appropriate self-management strategies can lead to better outcomes. Encouraging the adoption of self-care techniques, such as heat/cold therapy, rest, and activity modification, can effectively manage pain and maintain joint function.
Knee osteoarthritis is a prevalent condition that can significantly impact an individual's quality of life. While total knee replacement surgeries are often necessary for advanced cases, exercise and lifestyle interventions play a crucial role in the overall management and treatment of knee OA, offering numerous advantages over injections and surgeries.
By prioritizing exercise as a primary approach, individuals with knee OA can experience a wide range of benefits. Regular physical activity helps to reduce pain, improve joint function, enhance flexibility, and strengthen the muscles surrounding the knee joint. Additionally, exercise promotes weight management, cardiovascular health, and overall well-being, addressing key factors that may contribute to the progression and severity of knee osteoarthritis.
In contrast, injections such as viscosupplementation, while offering short-term pain relief, may not provide long-term benefits or significant improvements in functional outcomes. Their efficacy remains uncertain, highlighting the need for more reliable and sustainable solutions like exercise.
Moreover, lifestyle modifications in combination with exercises can help to prevent further deterioration of the knee joint and alleviate symptoms. These interventions empower individuals to take control of their condition, promoting self-management and reducing reliance on invasive procedures.
In summary, exercise emerges as the preferred and evidence-backed option for managing knee osteoarthritis. It offers a holistic approach that not only targets pain relief and improved joint function but also enhances overall health and well-being. While surgeries and injections have their place in advanced cases, the emphasis on exercise and lifestyle interventions can potentially prevent or delay the need for such invasive procedures, allowing individuals to lead active, fulfilling lives free from the limitations imposed by knee osteoarthritis.
Remember, it is always advisable to consult with a healthcare professional or a qualified physical therapist to design a personalized exercise program tailored to individual needs and capabilities. Together, we can embrace the power of exercise and lifestyle interventions to overcome the challenges posed by knee osteoarthritis and regain control over our joint health.
