In a 2015 study, researchers were trying to determine if the application of Cold Laser Therapy could successfully postpone the need for knee joint replacement. They took 100 elderly patients with symptomatic osteoarthritis and divided them into two groups. One group received protocol A which consisted of conventional physical therapy. The second group received protocol B which included the same physical therapy as in the protocol A group, but with the addition of Cold Laser Therapy. During a follow-up 6 years after the treatment, patients who received protocol B clearly benefited from the addition of Cold Laser Therapy, as only one knee needed joint replacement surgery. However, nine of the patients in the protocol A group that didn’t receive Cold Laser Therapy needed replacement surgery.
