With time, slight meniscal tears can heal by being treated with anti-inflammatory medicine, limited activity and physical therapy. Depending on the location of the tear, the torn portion of the meniscus may be either removed or repaired. Tears that are repaired with arthroscopic surgery are most successful in children and younger adults who have acute, traumatic tears. When this occurs, doctors use arthroscopy, a minimally invasive procedure, to make small incisions around the knee and insert a tiny camera to guide them through surgery. The meniscus can be repaired with sutures under arthroscopic guidance.
