Paper Abstract

The use of monopolar radiofrequency energy for thermal modification of tissue has expanded considerably since its rudimentary beginnings in the 1 9th century. It has been used in a number of medical fields and recently has been explored hi the orthopaedic arena. Monopolar radiofrequency energy mediates its effects through thermal tissue modification. It has been determined that type I collagen undergoes permanent structural modification between 60 and 80°C. Understanding of the mechanism of action of monopolar radiofrequency energy and the thermal properties of collagen has led to a number of clinical and basic research investigations into the use ofmonopolar radiofrequency energy to modifyjoint capsular tissue and thereby stabilize joints with excessive laxity. The technology has also been applied to ligamentous tissue. Recently, we have explored the effect of monopolar radiofrequency energy on the fibrocartilagenous structure of the meniscus. Thermal modification of musculoskeletal tissue has the potential to become a prominent modality for the treatment ofjoint disorders. It must be emphasized, however, that thermal treatment does have initial detrimental effects on tissue mechanical properties, and that long-term results have yet to be evaluated. Further controlled clinical and scientific studies should further clarify the advantages and disadvantages ofthis technique.
