Cold Laser Studies Prove Positive Results for Knee Pain and Cartilage Regeneration
Studies on Cold Laser Therapy and its Effects on Cartilage Regeneration
By Dr Schnee · July 12, 2010
Over the years, several studies have been performed to determine the effects of cold laser therapy on cartilage regeneration.
One study took a cartilage sample from the right knee of a 19 year old patient. Chondrocytes (cartilage cells) were isolated and suspended for cultivation, and cultures were incubated for 10 days. The cultures were then separated into 4 groups. The first three groups of cultures received cold laser treatments for 10 minutes for five consecutive days. Each culture had different laser parameters assigned to it. Group 4 was the control group and did not receive any treatments. The Groups that were treated with laser showed great results in terms of cell viability and higher levels of Calcium and alkaline phosphate as compared to the untreated group. This study concluded that laser therapy improved chondrocyte activity without causing any damage to the cell.
And in a separate study published in Biotechnology cold laser therapy was performed on holes drilled in mice’s ears to determine if cartilage would grow back. Mice were chosen as the subject because the chondrocytes (cartilage cells) in mice’s ears are similar to those in human cartilage. In the study, holes were drilled in both ears. The left ear was treated with cold laser therapy while the right ear was left untreated. The results indicated thatafter two days only the treated ear showed clear evidence of perichondrium (precursor to cartilage) while the untreated ear showed NONE. After four days the treated ear had significant ingrowth of perichondrium into the holeversus the control group were there was only an active perichondrium zone. Macroscopical and histological examinations revealed that cold laser therapy had a direct effect on cartilage regeneration.
Dr. Schnee’s Cold Laser Knee Program helped patients who were diagnosed with ‘bone on bone’ knee pain, and osteoarthritis of the knee experience knee pain relief so that they could avoid knee surgery.

Cold Laser Research
Here are just a handful studies that show how effective cold laser treatment for knee pain is:
There are over 35 years of worldwide clinical success, 2,500 published papers and 120 randomized, controlled trials for cold lasers. It is the only therapeutic modality with a cumulative effect on cells and tissues. Both NASA and the US Defense Advanced Research Projects Agency have engaged in cold laser therapy research over the last decade, with noteworthy success.

…We achieved significant improvement in pain relief and quality of life in 70% of patients.
Positive Outcomes for Infrared diode laser in low reactive-level laser therapy (cold laser) for knee osteoarthritis.
M.A. Trelles, J.Rigau, P. Sala, G. Calderhead, T. Ohshiro. Laser Therapy, (1991): 3(4): 149-153.
82% reported significant removal of pain and recovery of joint mobility. Cold Laser Therapy is concluded to be a safe effective and noninvasive alternative to conventional surgical and medical treatment modalities for DJD patients.
The Influence Of Low Level Infra Red Laser Therapy On The Regeneration Of Cartilage Tissue.
P. Lievens, Ph. Van der Veen.Abstract from Laser Florence 2002. Laser in Medical Science. 2002:17(4).
This study concerns the influence of Laser treatment on the regeneration process of cartilage tissue. There is no need saying that the regeneration of cartilage tissue is a very big problem in rheumatic diseases for example. The lack of blood supply is one of the most important factors involved. Lots of previous publications give us proof of the regeneration capacities of Laser Therapy. In this study we have chosen to experiment on cartilage tissue of the ear of mice….Microscopic as well as histological evaluations were performed on the cartilage regeneration of both ears… After the second day, only in the irradiated group there is a clear activation of the perichondrium (the connective tissue surrounding cartilage).
Beneficial Effects of Laser Therapy in the early stages of Rheumatoid Arthritis onset
Ailioaie C, Lupusoru-Ailioaie LM. Laser Therapy (1991) 11(2); 9-87
The purpose of this study was to determine the effects of laser therapy in pain reduction and /or recovery of patients at the onset of Rheumatoid Arthritis, comparatively with the traditional non-steroidal anti-inflammatory drugs (NSAIDS). Group 1 received laser therapy, Group 2 received placebo laser therapy, Group 3 was treated with only NSAIDS….The overall efficacy rate in these studies was 86% in the first group (who just had laser), 50% in the placebo group, and 40% in the NSAIDS treated group. After 4 months of treatment, our investigations showed the laser therapy group promoted the restoration of function, relieved pain and limited the complications of Rheumatoid Arthritis.
Improvement of Pain and disability in elderly patients with degenerative osteoarthritis of the knee treated with low power light therapy (cold laser therapy)

Low power light therapy (Cold laser therapy) is effective in relieving pain and disability in degenerative osteoarthritis of the knee.
Cold Lasers, Electrical Stimulation Curb Knee Pain
Boggs, Will MD. BMC Musculoskeletal Disorders. (June 22, 2007).
People with knee pain caused by osteoarthritis may find relief with… electrical nerve stimulation, (and) low-level laser therapy (cold lasers), research shows.
…Electrical stimulation and low-level laser therapy have fewer and less severe side-effects than NSAIDS, and unlike oral drugs they seem to… maintain the positive effect for some weeks after treatment has stopped…
Dr. Bjordal, MD said, “In our opinion, there is currently more short-term potential in refining these safe treatment methods for osteoarthritis than there are for drugs.”
Laser Therapy More Effective than Medication?
…From the findings of a recent Norwegian Health Technology Assessment Report, laser therapy was given the potential of becoming at least twice as effective as NSAIDS(non-steroidal anti-inflammatory drugs), if applied with optimal dose and energy… Although the number of laser trials is still smaller than for NSAIDS, the unequivocal scientific findings so far, has earned cold laser therapy a top spot in levels of evidence and treatment recommendations for knee osteoarthritis issued by the Norwegian Drug Agency.
Non-Drug Alternative for the Management of Chronic Pain

Most dramatically and recently, Australian researchers have identified a direct effect on the flow of cellular materials down the long axon that makes up the “wiring” of nerve cells. Researchers have discovered that laser-induced neural blockade is a consequence of such changes and provides a mechanism for…laser induced pain relief. The application of low level laser therapy for chronic pain may provide a non-drug alternative for the management of chronic pain.
Breakthrough in the Relief of Chronic Pain Without Drugs!
Goepp, Julius MD. Life Extension. October 2008: 63-70.
Dr. Norquist discusses his clinical outcomes for patients that received low-level laser treatments. “Out of 300 patients more than 90% have reported total pain relief. And more than half the others have experienced at least partial relief of their pain after 10 full treatments. Only about 2-3% of patients have truly had no beneficial effects.”
Cold Laser Research for Knee Pain
These are overwhelmingly positive results from various Cold Laser Therapy Studies on the Treatment of Knee Pain. Knee pain doctors continue to use Cold Laser Therapy to Relieve Knee Pain with great success. Many individuals report getting their own Scalar Wave Laser and using it at home to accomplish similar or better results due to the ease and convenience of getting more cold laser therapy treatments more often.
