摘要:

Summary:Since the early 1980s, different groups of researchers have tried to develop arthroscopic laser surgery. Laser technology may be ideal for use in arthroscopic surgery, because laser instruments are extremely small but remain powerful. Currently, the 2.1-μm holmium:YAG laser and the 1.44-μm neodymium: YAG laser are considered to be the systems that provide better results: Postoperative bloody effusions have been reduced and recovery times have been improved. Laser meniscectomy has been compared with conventional meniscectomy in several clinical studies, including the prospective study of the International Musculoskeletal Laser Society (IMLAS) knee research group. No studies have yet shown whether results are significantly improved by the use of a laser. As a single instrument, lasers can cut, coagulate, and ablate, depending on the method by which the laser energy is applied. It is the instruments themselves, not the procedure, that represent the most significant improvement. When used properly, lasers offer the arthroscopic surgeon the potential to decrease hemarthrosis, iatrogenic articular damage, and postoperative morbidity. Nevertheless, laser enthusiasts must exercise caution and specific procedures must be analyzed before arthroscopic laser surgery can be deemed better than conventional arthroscopic surgery. This is the aim of the IMLAS and its scientific board, under whose jurisdiction prospective studies are being conducted.

摘要:

Summary:Since 1989, we have been treating intervertebral disc prolapses with the method of percutaneous laser disc decompression (PLDD). We have also been conducting lengthy and detailed research to optimize parameter values. In this article we describe the results of our clinical trials (n=234). Furthermore, we describe the results of our basic research and provide a list of indications for patient selection and a summary of our clinical procedures for PLDD.

摘要:

Summary:Holmium-YAG laser surgery with noninvasive distractors for ankle arthroscopy, treatment of articular cartilage lesions, soft tissue ablation, and removal of loose bodies or bone fragments confers significant advantage. The small laser probe is easily maneuvered in the ankle joint. Laser decreases portal-related complications and postoperative pain, bleeding, and effusion; enhances surgical precision; minimizes damage to normal tissue; and appears to accelerate healing and rehabilitation. The operating time required with use of laser is approximately the same as that required with use of mechanical instruments.

摘要:

Summary:There are more CO2lasers currently in use in hospitals than all other “orthopaedic lasers” combined. This article discusses indications and contraindications, equipment, personnel, positioning and setup, and procedures for CO2laser surgery in the knee, along with laser-specific techniques, cautions, and postoperative care.

摘要:

Summary:Despite advances in rehabilitation and arthroscopy, few orthopaedic surgeons use the laser for arthroscopic synovectomy. The CO2laser, when used correctly, can be of great advantage to the orthopaedic surgeon when performing arthroscopic synovectomy.

摘要:

Summary:The holmium:YAG (Ho:YAG) laser has been utilized in the temporomandibular joint (TMJ) for ~4 years and has performed surgical technical procedures safely and efficiently. This laser was compared with the older mechanical instruments and found to be more precise and less traumatic to the joint soft tissues. In comparison to the neodymium:YAG laser, it was found to be safer and more precise, and it produced less soft tissue destruction. The currently performed Ho: YAG laser TMJ surgical procedures, treating articular disc dislocations, articular disc perforations, arthrofibrosis-fibrous ankylosis, and osteophytes of the mandibular condyle and/or the articular eminences, are technically described and the results are discussed.

摘要:

Summary:The 1.44-micrometer (μm) neodymium: YAG laser has been used for operative arthroscopic surgery since 1992. It has proven to be as effective as the 2.1-μm holmium:YAG laser.

摘要:

Summary:Over the last decade the free beam 1.06-μm neodymium:YAG, the 10.6-μ m CO2, the contact 1.06-μm neodymium:YAG, the 2.l-μm holmium: YAG, the 0.308-μm excimer, and the 1.44-μm neodymium:YAG lasers have been used clinically on patients for arthroscopic surgery. Serious complications have been attributed to the bare fiber delivery of the free beam of the 1.06-μ m neodymium: YAG (YAG) and the 10.6-μ m CO2lasers. Recently, avascular necrosis of bone has been implicated with the use of one type of a 1.06-μm neodymium:YAG (YAG). Over a decade ago, large postoperative hemarthroses were reported with the 10.6-μm CO2laser but have not been recorded since. These complications, as well as others, could have been avoided if the surgeons understood the potential hazards, as well as the expected tissue effects, proper energy settings, and surgical techniques. Even though serious complications have yet to be reported with the proper use of the 2. l-μm holmium: YAG, two recent misleading claims have been made. Nevertheless, any laser used improperly can lead to serious complications. Fortunately, proper training, knowledge, and technique can prevent serious problems.
