Over the past decade, there has been an increased awareness of the recognition and treatment of medial meniscus posterior root tears. Recent systematic reviews and meta-analyses have shown that surgical repair of medial meniscus posterior root tears is effective in improving patient-reported outcome measures and decreasing the progression of osteoarthritis when compared with nonoperative treatment or meniscectomy. The available techniques currently consist of transosseous suture fixation and direct suture anchor fixation, with transosseous repairs being the most frequently performed. Transosseous fixation relies on indirect fixation on the anterior tibial cortex, which may predispose to gap formation at the repair site. On the other hand, suture anchor fixation is technically demanding with arthroscopic placement of the anchor perpendicular to the tibial plateau at the posterior medial root insertion. Furthermore, re-tensioning of the construct is not possible with the current techniques. In this technical note, we present a knotless re-tensionable direct fixation technique using an anterior tibial tunnel, which has the advantages of direct fixation, a rip-stop suture configuration, a reproducible surgical technique, and the possibility of re-tensioning of the repaired meniscal root.
