Nine participants undergoing primary TKA submitted to spinal anesthesia, sedation, ultrasound-guided obturator and Femoral nerve Block analgesia, and photobiomodulation Therapy (FBMT) were evaluated regarding postoperative pain and morphine consumption. FBMT sessions were performed in the Immediate Postoperative period (IPO) and after 24 hours. Participants received 16.7±15 mg of morphine up to the third postoperative day. At IPO, mean pain score was 4.8±3.2 and 5.6±3.5, at rest and on movement, respectively. Photo biomodulation therapy can be considered an option for mitigating pain for patients undergoing TKA.

Série de nove pacientes submetidos a ATJ primária sob raquianestesia e sedação, bloqueio do nervo obturatório e femoral guiados por ultrassom, analgesia e fotobiomodulação terapêutica (FBMT) foram avaliados quanto a dor e consumo de morfina. As sessões de FBMT foram realizadas no pós-operatório imediato (POI) e após 24 horas. Os pacientes receberam 16,7±15 mg de morfina até o terceiro dia de pós-operatório. A dor em repouso foi em média 4,8±3,2 e a dor em movimento foi 5,6±3,5 no POI. A fotobiomodulação pode ser uma ferramenta para reduzir a dor em pacientes submetidos a ATJ.
