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.
Patients aged over 20 after Total Knee Arthroplasty in our institution would be candidate for recruitment. The patients will be randomized to receive routine post operative care or photobiomodulation therapy. The swelling extent and subjective outcome will be recorded.

bioimpedance of the surgical site will be measured for evaluation of swelling change
Time frame: the bioimpedance measured once daily since post operative day1 to day6 and at 2 weeks
pain score (visual analogue score)
patient reported pain score, from 0 to 100 points
Time frame: once daily since post operative day1 to day6

active range of motion of knee
Time frame: once daily since post operative day1 to day6
2 minute walk test
