Management of Meniscal Pathology: From Partial Meniscectomy to Transplantation.

Meniscal pathology is one of the most common structural knee issues seen and managed by the orthopaedic surgeon. An ever-evolving armamentarium of management options exists that are geared toward the elimination of symptoms and restoration of normal knee function. A common theme among these management options is to preserve meniscal tissue whenever possible through repair or minimization of meniscal excision, as the literature has shown that the loss of meniscal tissue can significantly alter the distribution of forces and contact stresses on knee articular cartilage, thus predisposing the joint to degenerative osteoarthritis. In the setting of meniscal injuries or insufficiency, various advances in repair techniques, use of meniscal allografts, and use of biologic adjuvants have been reported to help preserve and/or attempt to restore the native kinematic properties of the knee. It is important to explore meniscal function, its associated pathologies, and currently available treatment options that are supported by short-term and long-term clinical data.
