An individual's meniscus (cushion in the knee) is one of the most important ligaments in the leg providing stability, load bearing and preservation of the knee joint. It is also one of the most easily injured areas and difficult to fully heal. Researchers presenting their study at today's Specialty Day meeting of the American Orthopaedic Society for Sports Medicine (AOSSM) utilized MRI data to determine the potential for biologic healing following a meniscus tear.
"Little is currently understood about the healing of meniscus tears when a root repair is performed via the pullout technique," said Matthew D. Pepe, MD, one of the study's authors from the Rothman Institute of Orthopaedics in Philadelphia, PA. "Our study provides new insight into how this may occur."
Ten patients were identified for investigation, having undergone a medial meniscus root repair. There were five females and five males in the study group with an average follow-up time of 30 months following surgery. MRI evaluations demonstrated a new tear medial to prior repair in four of nine patients. These four patients show a lack of biologic healing of the root attachment. This indicates significant stress on the area following the repair. Similar findings have also been shown in studies evaluating rotator cuff repair.
"My colleagues and I hope that more fully investigating how meniscus tears heal will lead to improved clinical outcomes for our patients," said Pepe.
