Arthroscopic Medial Meniscus Posterior Horn Direct Anchor Root Repair: Transtibial Approach With Knotless Adjustable Aperture Fixation

The integrity of the posterior meniscus root attachment is vital for the preservation of knee joint biomechanics. Meniscus root tears treated nonoperatively or with meniscectomy lead to poor functional outcomes and progressive knee degeneration. Repair returns knee biomechanics back to the intact state and has an established record of positive mid-term to long-term results. Although transtibial pullout repair has been the gold standard, innovation is needed to overcome the limitations inherent to traditional approaches. The latest generation of transtibial pullout repair devices is adjustable, permits suture anchor placement directly into the root footprint, and has demonstrated encouraging early results in biomechanical analysis. This Technical Note describes an arthroscopic technique for medial meniscus posterior root repair that uses a knotless adjustable implant (SutureLoc; Arthrex) for aperture fixation via a transtibial approach with intratunnel soft anchor direct fixation and rip-stop suture configuration.
