Photobiomdoulation is the use of near-infrared light to relieve pain, stimulate healing and reduce inflammation. Swelling and inflammation is a common condition after orthopedics surgeries over extremity and spine. This study aim to evaluate the effect of photobiomodulation over patients after Total Knee Arthroplasty.
