Knotless Medial Meniscus Posterior Root Repair

Medial meniscus posterior root tears are common injuries, especially in the Asian world. This injury must be repaired where indicated to restore knee biomechanics and prevent arthritis. Suturing the meniscus using suture tapes provides good hold of the tissue. The use of a 70° arthroscope and creation of a transseptal portal improve visualization of the posterior compartment. Creation of a high posteromedial portal achieves the correct trajectory for the suture anchor insertion. A knotless suture anchor can be used to fix the posterior root at its anatomic attachment site. This obliterates the need for transtibial drilling for a suture pull-out repair or for knot tying and suture shuttling as for a conventional suture anchor.
