Effects of Photobiomodulation Therapy (PBMT) in Total Hip Arthroplasty
Effects of Photobiomodulation Therapy (PBMT) in Total Hip Arthroplasty
Osteoarthritis (OA), a chronic degenerative muscle disease characterized by cartilage wear,
 causes progressive joint deformity and loss of function leading to the indication of total
 hip arthroplasty (THA), when conservative treatments fail. Surgical trauma leads to pain and
 induces an immune response. Photobiomodulation therapy (PBMT) has proven effective in tissue
 repair by modulating the inflammatory process and promoting pain relief. It can therefore be
 part of the treatment. This study aims to analyze the effect of PMBT on inflammation and pain
 of patients who underwent total hip arthroplasty. The study consisted of eighteen patients
 who underwent hip arthroplasty and they received phototherapy in a period from 8 to 12 hours
 after surgery. We divided the patients into two groups (n=9 each) placebo and effective
 phototherapy. The patients were evaluated before and after phototherapy with 9 diodes,
 applied to 5 points along the scar (1 laser 905nm, 4 LEDs 875nm and 4 LEDs 640nm, 40.3J
 total), by visual analogue scale (VAS) and blood collection for analysis of the levels of the
 cytokines TNF-α, IL-6 and IL-8.
