The study evaluates whether the addition of low-level laser therapy into standard conventional physical therapy in elderly with bilateral symptomatic tri-compartmental knee arthritis can successfully postpone the need for joint replacement surgery. A prospective randomized cohort study of 100 consecutive unselected elderly patients with bilateral symptomatic knee arthritis with each knee randomized to receive either treatment protocol A consisting of conventional physical therapy or protocol B which is the same as protocol A with added low-level laser therapy.
The mean follow-up was 6 years. Treatment failure was deﬁned as breakthrough pain which necessitated joint replacement surgery. After a follow-up of 6 years, patients clearly beneﬁted from treatment with protocol B as only one knee needed joint replacement surgery, while nine patients treated with protocol A needed surgery.
It must be concluded that low-level laser therapy should be incorporated into standard conservative treatment protocol for symptomatic knee arthritis.
