Clinical Trial Summary

Osteoarthritis (OA) is a degenerative disease affecting joint cartilage and its surrounding tissue. It is the leading cause of disability in the elderly. The treatment of this disease remains limited to symptomatic relief and, ultimately, joint replacement. Despite the progress made in understanding the pathophysiology of OA, effective disease-modifying drugs are still lacking.

Low-level laser therapy (LLLT), also known as Photobiomodulation therapy, is a non-ionizing optical radiation in the visible or near infrared range of the spectrum. LLLI has been used widely for alleviation of pain, reduction of inflammation, and acceleration of wound healing. Specifically, it has been shown to reduce pain in chronic inflammatory related knee pathologies in pre-clinical and clinical studies. However, the recommended treatment protocol requires frequent treatments that translates to frequent visits at the clinic. Such a treatment regimen is difficult for Knee OA (KOA) patients and demanding of the clinical staff. Since the treatment itself can be self-applied easily, a home-use device would enable frequent treatments thereby improving patient adherence to the treatment.

In a pilot study, Kruglova et al [4] reported that 2 weeks of daily treatments with the home use B-Cure laser significantly reduced pain and increased flexibility in 20 elite athletes with KOA.

The purpose of the current study is to determine if B-Cure laser treatments, applied at home, by the patient or personal caregiver in a real-life situation, can reduce pain and improve functionality in patients with osteoarthritis of the knee.
