Infrared Diode Laser In Low Reactive-Level Laser Therapy (LLLT) For Knee Osteoarthritis

M. A. Trelles, J. Rigau, P. Sala, G. Calderhead and T. Ohshiro

Degenerative joint disease in particular in the knee is difficult to, cure successfully, at present often requiring surgical intervention. In addition the chronic degenerative joint disease patients often exhibit symptoms of both a physiological and psychological nature. A study is presented using high reactive-level laser therapy (LLLT) with an 830 nm infra red continuous wave gallium aluminum (or aluminium) arsenide (GaAlAs) diode laser with an output power of 60 mW. in light contact Laser therapy for a population of 40 patients (power density of approximately 3 W/cm²). Four points around the patella (knee cap) were irradiated for 60 s each (energy density of 18 J/cm² per point. total of 72 J/cm² per session) two sessions per week for eight weeks. Radiological, pain score and joint mobility assessments were made before the first session, immediately after at 4 months after the final LLLT session. All other medication and physical therapy was discontinued at least 15 days prior to the first treatment session. Thirty-three patients (82%) reported significant removal of knee pain and recovery of articular joint mobility. The remaining seven patients felt there was no significant effect following LLLT and returned to their original pre-therapy medication. The side effects were minimal. Low Level Laser Therapy is concluded to be safe, effective and non-invasive alternative to conventional surgical and medical treatment modalities for degenerative joint disease patients.
