Abstract

ABSTRACT Operations to treat meniscal injuries rank among the most frequent procedures performed by orthopaedic surgeons. Ongoing research on the natural history, basic science, and biomechanics of meniscal injury has called attention to the importance of preserving the meniscus to maintain normal biomechanics and functioning of the knee. The arthroscopic inside-out suture repair is currently the criterion standard by which other techniques are judged. Although it is usually not possible to identify menisci that are amenable to repair preoperatively, an overall assessment of the different patient factors along with tear characteristics as determined by preoperative magnetic resonance imaging and intraoperative findings will aid in making the decision to repair or excise the meniscal tear. The key principles of surgical repair, stimulation of circulation and proper reduction of the meniscus, should be kept in mind. Equally important, the meniscal tear must have the characteristics that allow for successful repair, without evidence of fraying or degeneration. A detailed knowledge of anatomy, as well as careful dissection and needle placement, will help to minimize complications.
