Arthroscopic all-inside meniscus repair.

The all-inside arthroscopic meniscal repair technique allows placement of vertically oriented sutures, which have the strongest pullout strength, across difficult-to-access posterior horn tears. These sutures are placed perpendicular to the tear, rather than obliquely, and without entrapment of the posterior capsule, resulting in a balanced anatomic repair. The posterior cannula allows excellent tear preparation and minimizes dissection. This may improve postoperative pain management and permit outpatient surgery. The all-inside technique minimizes neurovascular injury. This method has limited application and, therefore, requires that the surgeon learn more than one repair technique to repair tears anterior to the posterior horn. The main disadvantage is that advanced instruments (suture hooks and 70-deg lens) are required, as well as the surgical expertise to use them.
