[Arthroscopic surgery of the knee with CO2 laser surgery of the knee]

We present a preliminary report of our experience with the CO2 laser in arthroscopic surgery of the knee. Between August '94 and February '95 a total of 27 knee arthroscopies were done with the Sarplan 1030 30-watt CO2 laser for various knee problems, mostly degenerative arthritis. Complications such as subcutaneous emphysema and reactive effusion were noted, but no other significant problems. Although the arthroscopies were performed in a CO2 medium, which created some technical difficulties, the CO2 laser was very effective in neatly shaving the degenerative, articular cartilage, and in meniscal debridement. With the laser probe, some areas of the knee joint previously not accessible, can be reached and treated. Our impression is that with proper indications, laser arthroscopy has some advantages over traditional arthroscopy. Further technical improvement is needed before it is introduced for routine use.
