Morphologic Changes of Articular Cartilage after Surgical Affect by Laser Ray

Abstract

Influence of laser ray on the articular cartilage was studied in animal experiment (24 rabbits). Damaging affect of laser ray was directed to articular cartilage of knee joint and subchondral bone of the distal femur. Loading surface of internal condyle and nonloading surface of patellofemoral region were subjected to the affect of laser ray. All procedures were performed in aerial medium. For the detection of the value of laser damaging affect on surrounding tissues maximum working power of set «Lamin-1»- 70V was use. After laser affect the animals were killed on week one, two and three. Histologic examinations showed that under used power of the set laser affect effectively and maltraumatically dissected articular cartilage and subchondral bone.
