|All-inside meniscal repair on MRI. Suture tracks and anchors, new findings in the evaluation of meniscal repair.|
Menisci have a crucial role in knee biomechanics and the preservation of the integrity of the joint surface. Currently, the key to meniscal injuries treatment is the preservation of as much meniscal tissue as possible, to reduce osteoarthrosis .
Late generations of the all-inside suture technique are the most used nowadays because they are easy to use, avoidance of an accessory incision, shorter operating times and less risk of neurovascular injuries . The ideal tear to be repaired with sutures is a vertical, longitudinal, in the red-red zone of the posterior horn, with a length between 10 to 25 mm .
There are numerous different devices, but the later generation of all-inside meniscal repair technique uses an arthroscopic needle through the meniscus tear which deploys implants that serves as anchors at the outer surface of the meniscus/capsule, with a pre-tied intraarticular sliding-locking knot that compresses the tear (Fig. 1 , Fig. 2 and Fig. 3 ) [4,5].
Because of the circumferential orientation of the collagen fibers on the meniscus, the vertical sutures are more durable than the horizontal type, as this type of sutures does not cause any cleavage force on the circumferential fibers as the horizontal suture does [6,7,8].
Meniscal healing can take up to 4–6 months [9,10].
