Summary
Depending on the outer meniscus lesion, the surgical technique is selected. In most cases, an attempt will be made to reattach the tear in the outer meniscus using a meniscus suture in the OR. This reduces the formation of knee joint arthrosis.
In some cases, however, meniscal suturing is not possible. In these cases, the outer meniscus is partially or completely removed in the operation. A partial removal often leads to knee joint arthrosis, as the cartilaginous surface of the knee joint is destroyed.
For this reason, implantation of an artificial outer meniscus or a donor meniscus is often performed. The results of an implantation with biological materials show good results, whereas published data are not yet available for the implantation of an artificial meniscus.
