Radial Tear of the Midbody in Complete Discoid Lateral Meniscus: A Case Report.

To the best of our knowledge, there are no reports on the results of the repair of radial tears of the midbody of the complete discoid lateral meniscus (DLM). A 14-year-old female underwent meniscal replacement with autologous tendon transplantation for early re-tear after repair of the radial tear in the midbody of complete DLM. Two years after the tendon transplantation, there was no effusion or swelling, and the patient was able to exercise completely without symptoms. Repair without saucerization did not allow the placement of multiple sutures at the periphery and allowed destructive forces from the lateral femoral condyle to impact the tear site. Therefore, meniscectomy of the medial zone might be necessary to repair the radial tear of the midbody of complete DLM. Further follow-up is needed to conclude whether the tendon graft can replace the meniscus in the long term.
