Good news for those suffering from pain in their knees due to arthritis. A study recently published in The BMJ, of a sweeping review from over 200 studies involving over 15,000 participants, has revealed the best exercises to help ease knee arthritis pain (osteoarthritis). The findings indicate that walking, cycling, or swimming tops the list as being the best medicine for aching osteoarthritic knees, being the most effective at easing pain, improving movement, and enhancing overall quality of life.
Knee osteoarthritis develops when the cartilage cushioning the ends of bones wears down, leading to swelling, stiffness, and discomfort. It can affect any joint, but the knees are most commonly impacted. Around 30% of adults over the age of 45 show signs of knee osteoarthritis on X-rays, with about half of them experiencing significant pain and mobility problems.
If knee osteoarthritis is left untreated, it will likely worsen, leading to increased pain, stiffness, and loss of mobility, potentially causing disability and making daily activities difficult. Physical consequences can include joint deformity, fractures, and the erosion of tendons and ligaments, while mental health can be affected by anxiety and depression.
Physical Consequences
- Increased pain and stiffness: As the joint cartilage wears down, it can lead to severe pain and make it difficult to bend or straighten the knee.
- Loss of mobility: The ability to perform daily activities like walking or climbing stairs can become significantly impaired.
- Joint damage: Untreated osteoarthritis can lead to bone-on-bone friction, bone spurs, fractures, and the breakdown of tendons and ligaments.
- Joint deformity: The knee joint can become misshapen over time, such as developing a bow-legged appearance.
- Increased fall risk: Poor balance and weakness from pain can increase the risk of falling, which can lead to serious injuries like fractures.
Mental and Emotional Consequences
- Anxiety and depression: Chronic pain and reduced mobility can significantly impact mental well-being.
- Sleep disruption: Pain and discomfort can lead to poor sleep quality.
- Reduced quality of life: The combination of physical and emotional symptoms can lead to a significant decline in overall quality of life.
Other Health Complications
- Metabolic diseases: Untreated osteoarthritis may increase the risk for conditions such as obesity, heart disease, and type 2 diabetes.
- Weight gain: Reduced mobility can lead to a more sedentary lifestyle, which can contribute to weight gain.
Evaluating Knee Arthritis Pain Relief, Function, and Mobility
This study compared different types of exercise and aerobic training evidence across short and long-term outcomes. While all forms of exercise were found to be safe, based on their findings, the researchers recommend making aerobic activity the foundation treatment for arthritis knee pain.
Although exercise is the cornerstone of osteoarthritis care, many medical guidelines do not provide a clear direction on which kinds of exercise could be the most beneficial, specifically for knee osteoarthritis. This study set out to fill in the gap with evidence-based recommendations by analyzing the effectiveness and safety of several exercise approaches, drawing on 217 randomized clinical trials that involved 15,684 participants that compared multiple exercise categories, including aerobic, flexibility, strengthening, mind-body, neuromotor, and mixed programs against control groups.
Aerobic Exercises Deliver the Most Benefits
According to the researchers, across these studies, aerobic exercise was found to consistently rank the highest in improving participant outcomes among all of the exercise types tested.
Compared to the control groups, aerobic exercise effectively reduced short- and mid-term knee pain as well as improved function in both the short and long term. It also enhanced gait performance and quality of life over short and mid-term periods.
However, it was not the only form to show value; mind-body workouts likely provided a notable improvement in short-term function, neuromotor exercises likely boosted short-term gait performance, and strengthening or mixed routines improved function in the mid-term.
Additionally, it was noted that none of the exercise types resulted in more adverse events the the control groups, suggesting that they were generally safe as therapies.
The researchers did acknowledge some study limitations, but despite these, they describe their work as one of the most complete and current evaluations of exercise for managing knee osteoarthritis pain and believe it will help clinicians make more targeted recommendations.
Based on their work, the researchers advise aerobic exercise “as a first line intervention for knee osteoarthritis management, particularly when the aim is to improve functional capacity and reduce pain,” and suggest that if aerobic exercise is not possible owing to individual limitations, “alternative forms of structured physical activity may still be beneficial.”
