Arthroscopic surgery (or microsurgery) is a significant breakthrough in treating knee injuries. Its applications range from basic diagnosis to arthroscopic menisectomy, although its use in some procedures is still highly controversial. Many surgeons perform the diagnostic procedure, but follow this with the conventional surgical approach. Therefore, if arthroscopic surgery is being considered, the surgeon's plans and capabilities should be understood beforehand. The arthroscopic approach can be superior to traditional knee surgery because there is significantly less damage done to the joint and the recovery time is cut in half. Not all surgical procedures can be accomplished via the arthroscope; some that can be performed are menisectomy, debridement, and chondroplasty. Further information can be obtained from the American College of Orthopedic Surgeons. (DC)
