How can photobiomodulation relieve inflammatory knee pain?

Photobiomodulation (PBM) is a technique that uses light to help manage a variety of conditions, including inflammatory knee pain. This non-invasive method does not require the use of medication, and is becoming increasingly popular due to its many benefits.

What is photobiomodulation?

Photobiomodulation, also known as PBM, is a form of light therapy that uses light-emitting diodes (LEDs) and lasers to stimulate our body's cells.

The light used in PBM penetrates the skin and reaches the underlying tissues, where it acts on the cells to improve their function and promote regeneration.

Definition and basic principles

Photobiomodulation is based on the application of light at specific wavelengths, generally between 600 and 1000 nanometers. These wavelengths are chosen for their ability to penetrate tissues and be absorbed by mitochondria, the cellular structures responsible for energy production.

Mechanisms of action

The photobiomodulation process begins with the absorption of light by chromophores, molecules present in cells. This absorption triggers a series of biochemical reactions, including :

• Increased ATP production: by stimulating mitochondria, PBM increases cellular energy production, helping cells to function more efficiently.
• Reduced inflammation: light at specific wavelengths reduces inflammatory markers, thereby reducing tissue inflammation.
• Stimulation of blood circulation: PBM improves local blood circulation, which helps deliver oxygen and nutrients to damaged tissue.

The effects of photobiomodulation on inflammatory knee pain

Inflammatory knee pain can be caused by a variety of conditions, such as osteoarthritis, tissue damage or intense exertion. Photobiomodulation is a method for :

1. Reduce inflammation: photobiomodulation reduces inflammatory markers in knee tissue, helping to reduce swelling and pain.
2. Pain relief: among other things, by increasing endorphin production, PBM helps relieve knee pain.
3. Improved mobility: by reducing inflammation and pain, photobiomodulation improves knee mobility.

Photobiomodulation and various knee problems

Osteoarthritis

Osteoarthritis is one of the main causes of inflammatory knee pain. Photobiomodulation can help manage osteoarthritis symptoms by reducing inflammation and promoting cartilage regeneration.

Tendonitis

Tendonitis is inflammation of the tendons, often caused by intense exertion. Photobiomodulation helps to reduce tendon inflammation and accelerate healing, enabling a quicker return to activity.

Bursitis

Bursitis is inflammation of the bursae, the fluid-filled sacs that cushion the joints. Photobiomodulation can reduce the inflammation and pain associated with this problem.

How is a photobiomodulation session performed on the knee?

A photobiomodulation session performed on the knee consists of several stages:

1. Preparation: the patient is comfortably seated with the knee area exposed.
2. Light application: a device emitting light from LEDs and/or lasers is placed close to the knee. The light penetrates the skin and reaches deep tissue.
3. Duration: each session lasts between 15 and 30 minutes, depending on the severity of the problem and the practitioner's recommendations.
4. Frequency: for optimum results, several sessions may be required. The frequency and duration of sessions depend on the condition of the individual's knee and the intensity of the pain.

Results and benefits of photobiomodulation for knee pain

The results of photobiomodulation on inflammatory knee problems can vary depending on several factors, such as the severity of pain and individual response to treatment. However, many individuals report significant improvements after just a few sessions.

Thanks to photobiomodulation, it is possible to :

• Long-lasting pain relief: photobiomodulation offers long-lasting pain relief, helping to improve quality of life.
• Improve joint function: by reducing inflammation and increasing mobility, PBM contributes to better joint function.
• Improving general well-being: by helping to manage pain and inflammation, photobiomodulation improves people's general well-being.
