An original all-arthroscopic technique for bony fixation of lateral meniscus allograft via four tibial tunnels: A cadaver study.

Bone fixation of the two roots improves meniscal allograft positioning as compared to simple meniscal peripheral wall fixation. An all-arthroscopic 4-point bone fixation technique could provide rigid primary fixation and a more stable allograft. The technique was implemented on 8 fresh cadavers, under arthroscopy, via tibial bone tunnels at the posterior root, popliteal hiatus, anteromedial segment and anterior root, with cortical buttons for tibial graft fixation. Mean surgery time was 65±5minutes (range, 55-80min). The main difficulty lay in creating the tunnel to fix the anterior horn, which sometimes required an additional lateral portal. This 4-point bone fixation technique proved feasible and reproducible, and offers a novel means of stable primary fixation. LEVEL OF EVIDENCE: IV, cadaver study.
