Summary

Knee osteoarthritis (KOA) is one of the most common health problems around the world. According to this, several interventions have been used to treat this group of patients including pharmacological and non-pharmacological management such as weight reduction, behavior modification, and physical therapy. Recently, high-intensity laser therapy (HILT) has been used to treat patients with KOA. The results of previous studies showed that HILT could help to reduce pain as well as improved function in patients with mild to moderate KOA. However, there were still no standardized guidelines for HILT treatment in KOA. Also, no previous studies evaluated the efficacy of HILT in patients with severe KOA. The present study, therefore, recruited not only mild to a moderate degree but also severe degree. The study aim was to determine the efficacy of HILT in terms of pain relief in patients with mild, moderate, and severe KOA. The hypothesis was HILT would effectively reduce pain in patients with KOA compared to sham laser plus conservative treatment.

Conditions

Interventions

DEVICE

High-intensity laser therapy (HILT)

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.

DEVICE

Sham laser

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.
