Abstract

Different assemblies have endeavored to develop arthroscopic laser surgery. Various lasers have been tried in the treatment of orthopaedic problems, and the most useful has turned out to be the Hol-YAG laser 2.1 nm which is a near- contact laser. By using the laser as a powerful tool, and cutting back on the power level, one is able to better achieve the desired treatment effect. Clinical studies to evaluating the role of the laser in different arthroscopic knee procedures, comparing to conventional techniques, showed that the overall outcome attains a momentous confidence level which is shifted to the side of the laser versus the conventional for all maneuvers, barring meniscectomy where there is not perceiving disparity between laser versus the conventional. Meniscectomy continues to be one of the most commonly performed orthopaedic procedures. Laser provides a single tool which can ablate and debride meniscal rims with efficiency and safety. Chondroplasty can also be accomplished with ease using defocused laser energy. Both lateral release and soft tissue cermilization benefit from the cutting effect of laser along with its hemostatic effect. Synovial reduction with a defocused laser is also easily accomplished. By one gadget, one can cut, ablate, smooth, coagulate, congeal and with authentic tissue depth control The future of laser arthroscopic surgery lies in its ability to weld or repair tissues. Our research study has shown that laser activated photoactive dyes can produce a molecular bonding of collagen fibers, and therefore a repair 'weld' can be achieved with both meniscal tissues and with articular cartilage lesions.
