Ortho Angle

Alison P. Toth, MD  |  Issue: August 2009  |  August 1, 2009

In summary, meniscus extrusion may occur with symptomatic knee arthritis, especially when radiographs show advanced joint space narrowing. Extrusion may be treated differently than arthritis alone, especially in the young or middle-aged patient who is not yet a candidate for arthroplasty.

Dr. Toth is director of the Women’s Sports Medicine Program and assistant professor of orthopaedic surgery at Duke University Medical Center in Durham, N.C.
