Repair of a complete radial tear in the midbody of the medial meniscus using a novel crisscross suture transtibial tunnel surgical technique: a case report.

Complete radial meniscus tears have been reported to result in deleterious effects in the knee joint if left unrepaired. An emphasis on meniscal preservation is important in order to restore native meniscal function. In this case report, a complete radial tear of the medial meniscus midbody was repaired using a novel crisscross suture transtibial technique. This technique secured the anterior and posterior meniscal horns, which were released from their extruded and scarred position along the capsule, using crisscrossing sutures passed through two transtibial tunnels and secured over a bone bridge on the anterolateral tibia. In addition, the repair was supplemented with the injection of platelet-rich plasma and bone marrow aspirate concentrate to promote the healing of the meniscal tissue. Complete healing on second-look arthroscopy is presented, including in the previously unreported white-white meniscal zone.
