Short Term Efficacy of High-intensity Laser Therapy in Patients With Knee Osteoarthritis

"HILT was done by Multiwave Locked System (MLS) laser therapy combining 2 laser wavelengths (808 and 905 nm) in order to strengthen the effects of HILT. The laser was applied on medial, lateral and posterior parts around the knee joint. The total energy per session was 562.5 Joules (J) which was done 2-3 times a week for a total of 10 sessions.~Additionally, the participants received conservative treatment for knee OA such as education about the disease, proper activities, and exercise."

The control group received a sham laser (2-3 times a week for a total of 10 sessions) plus conservative treatment as in the intervention group. The laser machine was the same as in the intervention group; however, the laser was applied without releasing laser energy to the knee joint.
