Published: Last updated:

Knee osteoarthritis is a degenerative joint disease causing cartilage breakdown, pain, stiffness, and reduced mobility. It affects over 250 million people worldwide and is the leading cause of disability in older adults.

Prevalence: Affects approximately 10% of men and 13% of women over age 60

How Red Light Therapy Helps

Red light therapy reduces synovial inflammation, decreases pain signaling, and may support cartilage health. The WALT guidelines provide standardized protocols with strong clinical evidence supporting NIR wavelengths applied to specific joint points.
