Laser therapy, sometimes referred to as photobiomodulation therapy (PBM), low-level laser therapy (LLLT), or soft laser therapy, is a non-invasive medical procedure that interacts with tissue by using particular light wavelengths. It is utilized to lessen inflammation, ease discomfort, and quicken the healing process of knee joint range.

When compared to no treatment, low-level laser therapy has been shown to demonstrate significant differences in knee function, ambulation duration, and pain severity at rest and during activity.

Types of Laser Therapy for Knee Pain:

1. Class IV Lasers: These are high-power lasers that can penetrate deeper into the tissue, providing quick relief for acute and chronic conditions.

2. Class III Lasers: Also known as cold laser therapy, these are lower-power lasers that promote tissue repair and are used for more superficial conditions. You can also purchase a cold laser device for home use, which may be more convenient.

How Laser Therapy Works:

Laser therapy works by emitting photons, or particles of light, which are absorbed by the cells in the body. This absorption stimulates the cells to produce more energy, which in turn accelerates healing, reduces inflammation, and relieves pain. The process is painless and non-invasive, making it an attractive option for those seeking alternative treatments for knee pain.

How Red Light Therapy Can Help with Knee Pain
