Low level laser treatment of chondromalacia patellae

A randomized, double blind study of low level laser treatment of chondromalacia of the patella in 40 patients has been undertaken. Chondromalacia was established by arthroscopy and was related to subjective symptoms. Eight treatments were given during five weeks by a physiotherapist with the use of a GAAS pulsed laser, real or sham. Assessment of the location, quality and intensity of pain, and the influence on mood, gait, sleep, work, and sports was made before and after treatment including an eight to twelve week evaluation. No statistical difference was found between real and sham use of low level laser for the symptoms of chondromalacia of the patella.
