Meniscus sewing | surgery
The first thing we need to do when sewing meniscus is to perform standard access to a knee joint – we cut skin in two places. All internal elements of the joint are examined thoroughly – medial meniscus, lateral meniscus, joint cartilages and ligaments. Magnetic resonance showed the damaged spot, we confirm it during arthroscopy. In the medial section the meniscus is damaged. We use a hook to expose the damage. The meniscus base capsule damage portends well as far as sewing is concerned. We specify its size and then we take a decision on which repair method will be optimal. The surgery is intended to save a meniscus. We implant a stitch which is supposed to bring the damaged fragment to the joint capsule, as well as allow adhesion and generation of a meniscus. We use special tools to scarify meniscus tissue to increase healing process. Once we have developed the damaged place, we introduce the stitch through the special chute. It is a surgical suture combined with two anchors. A proper position of anchors in the meniscus allows inter-joint sewing. Once it has been sewed up, the surplus of suture is cut off. Another stage of the surgery is concerned with inspecting the meniscus stability. We see that the meniscus is well-attached to the joint capsule. Then we apply previously taken bone marrow which is rich in stem cells and growth factor. Thanks to saturation of the meniscus tissue with the preparation, the healing potential substantially increases. At the final stage we rinse and sew up the skin cuts.
