The best treatment for knee arthritis combines physiotherapy, exercise, EMS and laser therapy. Strength training around the knee improves joint support, while weight management and low impact modalities reduce inflammation. Non-invasive treatments like EMS and cold laser offer additional pain relief and tissue healing, making them ideal supplements to exercise. For many, this approach can delay or even eliminate the need for surgery.
Knee arthritis is a common condition that affects millions of people around the world. It occurs when the cartilage in the knee joint breaks down, leading to pain, stiffness, and reduced mobility. There are different types of knee arthritis, but the most common is osteoarthritis, which is often linked to aging, injury, or being overweight.
With so many treatment options available, it can be hard to know what works best. This blog looks at some of the most effective treatments for knee arthritis in simple terms, including some newer therapies like Electrical Muscle Stimulation (EMS) and laser therapy.
Understanding Knee Arthritis
Knee arthritis usually develops over time. The symptoms include:
- Pain when walking or standing
- Swelling around the joint
- A crunching feeling or sound
- Difficulty bending or straightening the knee
As the condition progresses, it can become harder to stay active and enjoy daily life. That’s why finding the right treatment is important.
What Are the Best Treatment Options?
There is no single ‘cure’ for knee arthritis, but many treatments can help manage the symptoms and improve quality of life. The most effective approach often involves a combination of methods.
1. Exercise and Physical Therapy
Exercise might seem like the last thing you want to do when your knee hurts, but it can help a lot. Strengthening the muscles around the knee supports the joint and reduces pain. Physical therapists can design a plan tailored to your needs.
2. Weight Management
Extra weight puts more pressure on your knees. Even losing a small amount of weight can make a big difference. Studies show that losing 10% of your body weight can reduce knee pain by up to 50% (1).
3. Medications
Over-the-counter pain relievers like acetaminophen or ibuprofen are often used. In more serious cases, doctors may prescribe stronger drugs or even injections like corticosteroids to reduce inflammation.
What About EMS and Laser Therapy?
Newer, non-invasive treatments like EMS and laser therapy are gaining popularity.
4. Electrical Muscle Stimulation (EMS)
EMS uses electrical pulses to make muscles contract. This can be especially helpful for people with knee arthritis because it strengthens the muscles without putting stress on the joint. Stronger muscles mean better support for the knee.
Some research shows that EMS can reduce pain and improve function in people with knee osteoarthritis (2). It’s often used along with exercise or physical therapy, not as a replacement.
5. Laser Therapy
Laser therapy, also called low-level laser therapy (LLLT) or cold laser therapy, uses light energy to reduce inflammation and promote healing in tissues. The light penetrates the skin without causing heat or damage.
Several studies have found that laser therapy can help relieve pain and improve movement in arthritic knees (3). It’s painless, non-invasive, and can be used along with other treatments.
Other Treatments to Consider
Some people also explore options like:
- Assistive devices, such as knee braces or walking sticks
- Supplements like glucosamine and chondroitin (though the evidence is mixed)
- Surgical options like knee replacement, usually as a last resort
Final Thoughts
Knee arthritis doesn’t have to take over your life. With the right combination of treatments, including newer options like EMS and laser therapy, many people find relief and return to the activities they love.
It’s always a good idea to talk to a healthcare professional before starting any new treatment, especially if you’re dealing with long-term pain or mobility issues.
