Endoscopic knee operations have become increasingly accepted during the last years. Meniscectomy is the most important of the endoscopic operations. The technique, developed in Linköping/Sweden, makes it possible to perform partial, subtotal or total meniscectomy according to what is needed to treat the patient appropriately. The technique involves the use of a pump system to distend the joint with saline, a mechanical assistant, a special knife with retractable blades, a grasping and a basket forceps. This very simple and inexpensive equipment makes all kinds of endoscopic meniscus surgery possible. The results of endoscopic meniscectomy have been rewarding. The time for sick leave is very short and the operation can be done on out-patients. Athletes ae back to sport usually within 4 weeks. There have been no complications.
